Glossary - U.S. Energy Information Administration (EIA)

Heat content: The amount of heat energy available to be released by the transformation or use of a specified physical unit of an energy form (e.g., a ton of coal, a barrel of oil, a kilowatthour of electricity, a cubic foot of natural gas, or a pound of steam). The amount of heat energy is commonly expressed in British thermal units (Btu).

Steam locomotive - Wikipedia

How a steam locomotive works, in 100 words ; Coal or oil is directed into the firebox (item 27 in the large diagram below), where it burns at high temperature. The firebox is surrounded by water in the boiler, and many tubes (28) extend from the firebox's front along the boiler barrel (29). Very hot gases travel through these tubes and up the smokestack/chimney (33).

Life Cycle Assessment of Coal-fired Power Production

coal was performed in order to examine the environmental aspects of current and future pulverized coal boiler systems. Three systems were examined: 1) a plant that represents the average emissions and transformation of raw materials into useful products and the final disposal of all products and by- coal mine. For the Average and NSPS

Why I replaced my new gas boiler with a heat pump - Foresight

Jun 26, 2019 · My heat pump avoids 1313 kg CO2e a year. It means that after less than 1.5 years, a heat pump starts saving carbon compared to a gas boiler, even if the gas boiler is replaced before the end of its life. Hence, from a carbon perspective, it makes sense to replace a gas boiler
