Feedwater used in a steam boiler to transfer heat energy from the fuel burning area to mech. Energy of spinning steam turbine
Rectangular furnace, pulverized coal is blown in from fuel nozzles at 4 corners. The coal then burns quickly and forms a fireball at the center (seriously, a fireball!!!). Steam enters from the turbine generator and is pumped into the bottom of the condenser, where pumps recycle the condensed steam from the feedwater.
Power plants emit 40% of total U.S. carbon dioxide pollution, the primary global warming pollutant.
Although coal-fired power plants account for just over half of the electricity produced in the U.S. each year, they have been responsible for over 83% of the CO2 pollution since 1990.
