how we calculate the coal consumed to generate xxx MW say 12 hrs or 24 hrs in CFBC boiler please help
Cfbc stands for circulating fludised bed combustion where as afbc is for atmospheric fluidise bed combustion afbc bed fluidising velocity is approx 4 m/s and in cfbc boiler fluidising velocity is 9-10 m/s. cfbc having low SOx & NOx comparative with afbc cfbc having higher efficiency up to 98.5 % then afbc boiler,cfbc boiler power consumption is more comparative to afbc.
afbc has high turn down ratio,burner arrangement is simple,low grade coal can be burnt efficiently,so2 emission can be controlled,
Well it depends on on the coal Gasification plant capacity i.e 1.3m 0r 1.8m The difference is that of Coal Gas generation /produed. Depend on the size of Boiler/Furance & various factor.
boiler+coal=steam engine
hi, Thermal based power plant have large type of coal consumption and secondly the cement and steel industries have large coal consumption
A boiler in a coal power station is responsible for converting water into steam. The coal is burned in the furnace of the boiler, producing heat which is used to generate steam. This steam is then used to drive a turbine, which spins a generator to produce electricity.
boiler + coal
First in order to calculate the heat content of a particular type of coal, an ultimate analysis must be done. Then the combustion efficiency of the coal must be calculated, the boiler efficiency is then determined by a boiler "acceptance test", or heat balance. The steam is then run through an engine driving a generator to determine the total plant efficiency thus determining how much coal is burned to produce a set amount of electricity. Several publications on Steam power plant operation explain these efficiency tests in more detail.

Boiler+Coal
Its Metal + Steam . That Is What Makes A Boiler . Sincerely -The Strange Answerer AKA Dgjojo2
