Aug 14, 2017 · To produce one ton of steam, You need 666000 kcal. To produce one ton of steam, and every one m3 of gas gives 9520 kcal. So, around 69 m3 of gas will produce 1 ton of steam.
Coal is burned in the boiler furnace to produce heat. Carbon in the coal and oxygen in the air combine to produce carbon dioxide and heat. Stage 2 is a thermodynamic process. The heat from combustion of the coal boils water in the boiler to produce steam. In a modern power plant, boilers produce steam at high pressures and temperatures.
This question cannot be answered as asked. It takes different amounts of energy to produce steam at different temperatures and pressures. If the steam is saturated (at boiling point for the pressure it is produced at), some water may be entrapped
The energy density of coal, that is its heating value, is roughly 24 megajoules per kilogram (approximately 6.7 kilowatt-hours per kg). For a coal power plant with a 40% efficiency, it takes an estimated 325 kg (717 lb) of coal to power a 100 W lightbulb for one year.
The amount of steam produced by 1 ton standard coal at a boiler depends on the coal consumption and electricity consumption and they are steam boiler energy consumption indicators. Units of measurement are kg standard coal / ton of steam and kWh / ton of steam.
