The energy efficiency of a conventional thermal power station is defined as saleable energy produced as a percent of the heating value of the fuel consumed. A simple cycle gas turbine achieves energy conversion efficiencies from 20 to 35%. Typical coal-based power plants operating at steam pressures of 170 bar and 570 °C run at efficiency of 35 to 38 %, with state-of-the-art fossil fuel ...
The AFUE rating for an all-electric furnace or boiler is between 95% and . The lower values are for units installed outdoors because they have greater jacket heat loss. However, despite their high efficiency, the higher cost of electricity in most parts of the country makes all-electric furnaces or boilers an uneconomic choice.
A fossil fuel power station is a thermal power station which burns a fossil fuel, such as coal or natural gas, to produce electricity.Fossil fuel power stations have machinery to convert the heat energy of combustion into mechanical energy, which then operates an electrical generator.The prime mover may be a steam turbine, a gas turbine or, in small plants, a reciprocating gas engine.

The Coal Gun is manufactured in Pennsylvania and burns anthracite coal. Although normally used in hydronic boiler applications, the Coal Gun can be adapted for use with forced hot air systems through the use of a water to air heat exchanger. With the optional steam control and fittings package, it can be used in steam heating applications as well.
Energy content of coal is given in terms of KiloJoules (kJ) per Kilogram (kg) of coal as the Gross calorific value (GCV) or the Higher Heating value (HHV) of coal. This value can vary from 10500 kJ/kg to 25000 kJ/kg depending on the quality and type of the coal. You should have an idea of the type of coal, or the source or mine from where the ...
• One million Btu's is the heat equivalent of approximately 7 gallons of No. 2 heating oil or kerosene, 293 kWh of electricity, 976 cubic feet of natural gas, 11 gallons of propane, 125 pounds of air-dried wood, 121 pounds of pellets, or 71 pounds of coal.
The coal hot water boilers from Keystoker make for a powerful heating option to use in your home, or commercial building. Using anthracite coal to burn, or oil if you purchase a dual fuel kit, this coal burning boiler can produce anywhere from 85,000 to 528,000 BTUs.
In the row corresponding to that coal price, you will find the prices that other heating fuels would have to be to match the heating value of coal. If coal costs $130 per ton, to get the same amount of energy for the same cost, heating oil would have to cost $0.65 per .
