Clean Coal Technologies and Alternative heating

According to the World Coal Institute, reserves of coal worldwide top 847 billion tons; enough to last 130 years at the current rate of production and provide more than enough fuel for alternative coal heat. Contrast that with current oil and gas reserves (currently set to last 42 years and 60 years respectively) and it becomes clear that clean coal is a natural resource with enormous potential for the transition from fossil fuel to self-sustaining green energy. The hardest type of coal burns the cleanest and is called 'anthracite coal'. Rich reserves of anthracite coal can be found in Pennsylvania in the U.S., the Crow’s Nest Region of the Rocky Mountains in Canada, and in various spots in the Andes mountains in Peru. At the present time, most of the anthracite coal mined in North America comes from anthracite coalmines in Pennsylvania.
Softer grades of coal can also be burned as fuel, but are used less and less often because they produce substantial pollution in the form of sulfur and carbon dioxide. Even anthracite coal produces unacceptable levels of carbon dioxide when it is burned commercially. Clean coal technology refers to various attempts to reduce coal emissions so that the use of this plentiful natural resource does not contribute to global warming. Currently, electrical power plants burn the most coal and are the most heavily invested in clean coal. They also contribute most heavily to global warming.

Some Safer methods of cleaning up coal emissions:

GCC or Integrated Gasification Combined Cycle turns coal into gas before it is burned and removes the impurities so they don't end up in the atmosphere.
'Carbon capture' or carbon sequestration refers to a variety of experimental technologies that remove toxic gases from anthracite and softer grades of coal so they can be burned safely.
De-watering of lower grade coals removes moisture content so that low quality coal is more combustible and burns cleanly.

Clean coal technology is controversial. Many environmentalists point out that widespread application of IGCC and other carbon capture methods will not be possible until 2025 at the earliest, and require major monetary investment. Clean coal advocates point out the obvious need for a fossil fuel that can help the world transition to green energy, and to the fact that coal is still the most plentiful choice. A production infrastructure is also already in place. Alternative coal stoves for home use have existed for many years. Home coal burners can be a good option in regions where access to coal is easy and the grade of coal available is good. Coal stoves, like wood stoves require regular maintenance and an understanding of the technology in order to keep them operating safely. High efficiency alternative coal furnaces for home use are also available.
Today’s coal burning stoves and furnaces are cleaner than the home coal burners of the previous century, but alternative coal heat is not right for everyone. Consider the maintenance requirements, cost, and affordability of local coal in order to make an informed choice about whether alternative coal is right for you.

Choosing the Right Geothermal Heat Hump

A geothermal heat pump is a system of home heating in the winter and home cooling in the summer that uses the temperature of the earth itself to exchange both hot and cold air. Only volcanic areas of the world tap actual heat from underneath the ground, but because a heat pump uses the relatively constant temperature below the ground as a means to exchange heat rather than generate it, when underground conduits are combined with a heat pump, any part of the country can use the earth for home heating and cooling.

How does a geothermal heat pump work?

The ground just below the surface is warmer than the air above it in winter and colder than the air above it in summer. Underground temperatures stay fairly all stable year round. Although you might not be comfortable if you simply set your house to the underground temperature at any given moment, a geothermal heat pump can regulate the temperature of your house by exchanging cold temperatures for warm ones in winter and warm ones for cooler ones in summer, using the underground temperature as a constant. In other words, a geothermal heat pump uses the constant underground temperature of the earth to exchange heat with the ground, taking it out in winter and putting it back in summer. Unlike air-source heat pumps (such as those in air conditioners or refrigerators) that simply extract heat from the air and then expel it outdoors, geothermal heat pumps perform an actual heat exchange. Heat exchange uses less energy than heat extraction from the air.
A geothermal heat pump is an extremely energy efficient, cost-effective way to heat and cool a home. The same system does both and uses a much smaller amount of electricity to do it than any other conventional home heating and cooling system. When combined with solar panels to generate the electricity needed, a geothermal heat pump can for all practically purposes become a self-sustaining system that uses renewable energy only and leaves a minimal carbon footprint. A geothermal heat pump is affordable to operate but can be very expensive to install. For example, installation of a geothermal heat pump in an existing home can cost upwards of $11,000. Installation requires digging trenches for the underground exchange system, so the initial investment can be substantial.

Air conditioning with an air to water heat pump

However, the return on the installation of a geothermal heat pump is immediate and large. A new heat geothermal heat pump will save a family living in an average-sized home up to 75% a year on heating and cooling costs. So, for instance, if you spend $3600 a year on heating and cooling (not at all a usually high amount at today’s energy prices), you will save as much as $2700 a year right away. At that rate, you can expect to recoup your investment in four to five years. For 2009 and 2010, the U.S. government is providing a $1500 tax credit to homeowners who install a geothermal heat pump in order to encourage people to invest in renewable energy. If you go a step further and install a geothermal heat pump with solar panels to fuel it electrically, after about five years you will have a source of nearly cost-free heat and cooling for your home and family. For more information on geothermal heat pumps as well as links to various state and local programs that provide tax credits or help with installation.

Choosing a Floor Furnace - Home Heating Options

The installation of a floor furnace is a something you should consider if you are planning on revamping the heating system in your home or planning an addition to your living space. The benefits are considerable. A floor furnace is aesthetically pleasing, easy to control, energy efficient and economical and provides some health benefits as well. Floor furnaces have been in use for centuries, beginning in early Roman times, and is rapidly gaining popularity. They are typically installed in bathrooms and atriums since they provide heat to the room individually, but are a good choice for any room. They are ideal anywhere that space is limited or there is the need to eliminate wall mounted or baseboard heaters that can interfere with the visual appeal of a room. Since they are installed underneath the floor, they are virtually invisible.

A floor furnace is installed below the flooring of the room and is not supported by the ground. The piping system hangs from the floor and must clear the ground by a minimum of six inches. The furnace unit itself is also located below the floor and should maintain a minimum clearance on every side from any combustibles. A grate will be installed to allow for easy access to the furnace unit so that maintenance is possible. The grate should be at least six inches away from any walls and be a minimum of 24 inches away from any combustibles of 2 sides. The remaining sides of the grate should be a minimum of 12 inches any doors or other combustibles such as drapery or furniture. Also keep in mind that the grate should be more than 60 inches from any structures such as a stairway or bulkhead. Be sure that the floor furnace is installed in a configuration that will allow for servicing or replacement of any components of the heating unit. Check your local building codes to verify that installation of a floor furnace is permissible in your area; not all areas allow them.

The floor furnace has a boiler that is fueled with natural gas or propane. Water is heated by the boiler and then run through the piping system that is installed under the flooring. These pipes will transfer the heat to the room through warm air convection. The warmth of the floor creates this warm air convection, which provides a comfortable temperature. This exceptional method of heating a room is really very straight forward and effective. It tends create a "climate" through the even distribution of the heat. A wall thermostat is installed on the wall in the same room that the floor furnace is heating. It is best to install the thermostat in the same room in order to make it more convenient to regulate the temperature in the room. Other than the grate on the floor, this is the only part of the furnace that is visible. A floor furnace is available in different sizes, which will of course mean a range of prices. Models are available that use either natural gas or propane and range from 32,000 BTU to 65,000 BTU. They usually start at around $1000 and end up at around $1300. If you cannot find a floor furnace available locally, be prepared to pay extra for shipping the unit to your location.

The use of a floor furnace can provide an overall energy savings of 15-40% when compared to other methods. In addition to the energy savings, this form of heating will keep the moisture content in a room at a relatively low level. This is very beneficial to any members of your family that may suffer from asthma, allergies, or any breathing difficulties. Installing a floor furnace is a decision that will make you feel warm all over.

Air to water heat pumps home heating

The original heat pumps were air source heat pumps for addition to a furnace. Then came ground source heat pumps which could deliver heat to either ducted or in-floor hot water heating systems. These systems are a fair bit more efficient but much more expensive than an air source unit. But what about an air source heat pump for in-floor hot water heating systems?

Attempting to provide a more affordable heat pump system in a home with hot water heating, some contractors utilized a device called a desuperheater. It is basically a heat exchanger here the water in the system flows across the coils which carry refrigerant which has been heated by the outdoor unit. The outdoor unit would be a standard air source unit intended to be hooked up to a coil made to pass heat to air flowing through ductwork. Instead, it would be hooked up to the desuperheater. While this was a cheaper option, the outdoor unit was unfortunately not intended to fulfill the demands of a hot water heating system, which requires different levels of heating at different times.
Only recently have a few different manufacturers began to distribute air source heat pumps made specifically for in-floor hot water heating systems. These units are often called or reverse cycle chillers. The second name refers to their technological resemblance to water cooling machines, but they can now run in reverse to heat water also. Note that these units can only be used with in-floor heating systems. No type of heat pump can be used with baseboard heating systems because they require higher water temperatures that only a boiler can provide. In an air to water heat pump, the heated refrigerant does not enter the house. Instead, it is used to heat water inside the outdoor unit. The heated water is then pumped into the home, where it enters a second heat exchanger. In this heat exchanger, the water from the outdoor unit transfers its heat to the water flowing through the distribution system. If it is a very cold day, the heat pump may act as a pre-heater before the water enters the boiler. On mildly cool days, the boiler will be bypassed.

Air conditioning with an air to water heat pump

The piping of a hot water heating system is unsuitable to deliver cold water to provide air conditioning. This means that, with any type of heat pump, fan units must be installed in rooms where cooling is desired. Cooled water from the outdoor unit will be run through pipes to these units. These units are similar to room air conditioning units in appearance. Of course, if cooling is added to several rooms, this will entail a large increase in the cost of the job. So, adding a heat pump with whole house cooling will cost a fortune with an in-floor heating system, but in the end you’ll have the ultimate heating and cooling system: radiant heating comfort, heat pump efficiency, and air conditioning. An air to water heat pump should have an HSPF efficiency rating similar to air source units, or possibly a bit lower. You can read the article on air source heat pumps for a discussion on how to estimate energy savings with a heat pump.

Advantages of an Outdoor Corn Boiler

Have you considered getting an outdoor corn boiler? With heating costs rising and concern about use of petroleum for heat and energy production, it's no wonder that more people are beginning to wonder about alternative options for heating their homes. One lesser known heating method is the corn boiler. These outdoor heaters burn renewable fuels, such as wood pellets or feed corn, and offer a cost-effective, energy efficient, and safe alternative to standard heating methods. However, it's important to install and operate your furnace correctly and according to the recommendations of the manufacturer if you want to get these benefits. Operating an outdoor boiler inappropriately can lead to greater emissions and pollution. However, when installed and used correctly, this alternative heating option can offer significant benefits. For instance, since outdoor corn boilers are located outside, the risk of a fire inside the home is eliminated. As well, the possibility of smoke and carbon monoxide buildup that comes with indoor wood burning isn't a problem. Outdoor corn boilers are also inexpensive. People who own outdoor furnaces can find themselves paying a quarter to half as much for heat, depending on fuel cost. Most outdoor furnaces don't need to be loaded often. Once or twice a day is common for versions that burn wood, and those with corn hoppers can sustain their heat for days on one load of wood. Some people have even managed to maintain heat for two weeks without having to refill their outdoor corn boiler.

Outdoor furnaces also offer a more even heat than wood stoves. This is because a thermostat controls the heat they produce. Fireplaces and wood stoves are notorious for hot spots and cool spots. Using an outdoor corn boiler removes this problem entirely, as the heat from the furnace enters the home via water radiators or forced air. It's important to remember that even efficient methods of heating like outdoor corn boilers can be affected by outside factors. For instance, inefficient windows and doors, colder outside temperatures, cold air entering the furnace, and poorly insulated buildings are all capable of decreasing furnace efficiency. These problems can be rectified by insulating the buildings that are being heated, installing efficient windows and doors, and keeping cold air out of the furnace.
There are many myths about corn and wood furnaces that prevent people from using them. You might have heard that burning corn or wood is bad for the environment. In fact, these fuels are carbon neutral – burning them doesn't cause a net increase in greenhouse gas emissions. Heating with these resources also reduces our dependence on fossil fuels, such as oil, which do cause a net increase in emissions. Heating an average home with wood can save sufficient nonrenewable fossil to operate a car for a whole year. People have also said that outdoor furnaces provide a nuisance and have greater particulate emissions than regular wood burners. While this can be true if the owner of these stoves is irresponsible, the same can be said of cars and of standard wood stoves. A properly installed and operated outdoor corn or wood boiler has emissions that are comparable or less than wood stoves. New EPA guidelines mean that outdoor boilers are cleaner than ever.

This is in addition to Giza pyramids and the pyramids khuphura cepasa also known as the Pyramid. It has been created by the million blocks of stone. Khuphura Great Pyramid was created in 20 year and was created B.C 2560 jobs over complete. The height of 146.5 meters and about the first 3,800 years of human development as the world's top architecture was known. Egyptian pharaoh of the fourth emperor is khuphura burial. The Seven Wonders of the World is one. The ancient Egypt would rule pharaoh kings. The tomb is built on the grave as the pyramid templates. Misare chotabara have 75 pyramids. Giza is a large and most attractive of which khuphu Pyramid also known as the Pyramid. It was created about 5000 years BC. Its height is about 481 feet. It was established 755 square feet land. It took the time to create a new 20 years and handwork 1 million labors. Pyramid was built a huge part of stone. Volume was about 60 tons of stone, a weight and length of 30 to 40 appears.

It also has a half circle of playhouse where could sit together about 3000 visitor.  The city of Petra was defended and economically prosperous. All the side of Petra was a high hill and charming waterfall. The Petra would control all   main commercial ways which stands west of Gaza, North of Bosra and damaskas, beside of red sea of akuaba and liuse and North side of desert. During Roman rule, Petra quickly destroyed when they started trading centrally in ocean. In A.D 106 Romans were taken the provinces of comprising Arab Petra. The second and third centuries the importance of city reduces and takes mostly commercial areas Pamira city. In seventh centuries, Muslims take and the twelfth century it was occupied krusedara when it is destroyed. In 363 centuries, the earthquake destroyed the dalanagula and lost the run of the water system. In the middle age Petra ruins the central point. In the thirteen century to see Petra Egypt sultan Baibaras. After many years, this ancient city was discovering Swiss Paribrajak Johan Burkhardat in 1812. John William bargan said his description of Sanete Award winner famous “A rose-red city half as old as time”. But Bargan can not go Petra. Because, after First World War there could be on go Europeans and local people there were arms. UNESCO confirmed it as a global heritage place in 1985.

Grand Wall of China

Every one has a concept about the Great Wall of China. Of the world seven wonders is most magnificent place Great Wall of China. Actually, it’s made of man and its matter of joyful the strange plan many years active and made of many years ago. It’s very strange that how three dynasties are together the works was running. The wall is made about one-two million dead of Chinese. The wall has so far from of inhabitant’s area. It hears to people, if someone dead of working time that would cover down soil. The Chinese are so hard worker that are flourishing their vast working. The wall for resting has observed chair, reserved weapons, horse and army resident and would work sending alarm. Cantonment and academic centers are situated a long way. The greatest of wall boundary of solder was stronger to communicate and cautious about enemies monument. To show for an expedient hill and others high place was setup alarming tower. The Great Wall of China says Chinese language “sung son” which is made stone and soil a long row. These are made from B.C sixteen to B.C five for maintaining the north site of china. The same type of wall was made between B.C 220 and B.C 200 middle time of the china first sovereign khin-shi-huyaar was built the largest wall. At present, it’s situated of wall various far from north site and has very little remaining. Presently, the wall is built of the royal family. The greatest wall of world of china has made man’s hand masonry. The wall is about 5 to 8 meters high and 6532 kilometers long. It has started sanghipas and ended lopnur spot. The main part of wall construction was started about B.C 208.During the Construction work is starting choynic king emperor. The first sovereignty of china Qin shi Huang it use at first and build up a long wall to from enemies hand. Without natural restrictions of china others area for giving lookout and north of china the Hsiung Nu produced of opposite the first level secured.
