Answer (1 of 6): Amount of fuel required in 1 tph boiler depends on type of fuel used in boiler i.e. different fuel have different calorific value. Formula for calculating fuel: Fuel Consumption = steam quantity* latent heat / Efficiency * Calorific Value FOR EXAMPLE: For 1

2015/3/17 · Steam, Boiler, and Blowdown Pressure are the same. Combustion Efficiency is the % of fuel energy that is directly added to the feedwater and not otherwise lost or used. Blowdown Rate is the % of incoming feedwater mass flow rate that leaves the boiler as a saturated liquid at boiler pressure.

Answer (1 of 6): Water does not change its mass on going from liquid to gas, so to produce one ton of steam per hour you need one ton of water per hour, plus a safety margin to ensure that your boiler doesn't run dry.

Steam power generation Fuels such as heavy oil, LNG (liquefied natural gas) and coal are burned inside a boiler to generate steam at high temperature and high pressure. This steam is used to rotate the impeller of the steam turbine. This drives the power generators

Trevithick was the first to successfully use high-pressure steam (then known as "strong" steam). Until ca. 1800, the weakness of existing boilers coupled with the influence of James Watt had generally restricted steam boilers to very low pressures or "weak" steam.

Heat in the boiler boils the water into steam. The steam pressure turns the steam turbine and the generator generates electricity. A combined cycle power first generates gas by burning fuel in the compressed air. Pressure of the gas rotates the gas turbine and the generator creates electricity. Moreover, exhaust heat from gas turbine is
