Steam Calculators: Boiler Calculator

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 as a saturated liquid at pressure.

Scaling in boilers - Lenntech

Boiler scale is caused by impurities being precipitated out of the water directly on heat transfer surfaces or by suspended matter in water settling out on the metal and becoming hard and adherent. Evaporation in a causes impurities to concentrate. This interferes with heat transfers and may cause hot spots. Leading to local overheating. Scaling mechanism is the exceeding of the ...

How to Calculate the Coal Quantity Used in a Power Plant ...

Coal Quantity. Since coal has a heat value of 20000 kJ/kg for producing one kw.hr we require (10765 / 20000) 0.538 kg of coal. This translates to (0.538 x 100 x 1000) 53800 kg/hr (53.8 T/hr) of coal for an output of 100 MW. Cost. Basic cost depends on the market conditions.

How much CO2 and pollution comes from burning coal?

Coals most notorious byproduct is carbon dioxide (CO2). Every million BTUs released from burning coal releases an average of 208 pounds of CO2 (see note below). Since a ton of coal has 20.025 million BTUs that means it creates 4172 pounds of CO2 when it is burned. Running our 100-watt bulb for one year will produce 1670 pounds of CO2.
