Natural Science Forum / Physics / General Physics / July 2008Calculate heat of coal fired boiler
Hello, can you recommend me useful links about informations on how to calculate heat of coal fired boiler. Boiler is with natural circulation with drum. It has 6 coal mills. I wonder if possible to calculate input heat to a boiler, and what variables I need? Thank you > Hello, > [quoted text clipped - 4 lines] > > Thank you In the absence of a better reply... The energy density of coal is between 13 and 30 MJ per kg... http://hypertextbook.com/facts/2003/JuliyaFisher.shtml So multiply by the number of kg per second burnt to get the input power in watts. This calculation is very crude because it doesn't tak into account how efficiently the coal is burnt. |
