Pulverised Coal - an overview | ScienceDirect Topics

Pulverized coal firing ensures complete combustion of coal, thus ensuring higher efficiency of steam generators. It is predominantly adopted in large coal-fired utility boilers. The finer the grinding of coal, the more efficient its combustion. The total time required from entry of a coal particle to a furnace to combustion of the particle is very short. This time, however, is dependent on various factors. The heart of a pulverized coal-fired boiler is the pulverizer…

16/02/2011· You can keep everything except the actual transducer heads out of the coal-side of the mill and the area above the seal and beneath the casting is about a clean as you'll find in the mill. Not sure how you can calibrate and whether the surface finish on the casting is good enough to allow for decent readings. The only other idea I have at the moment would be to monitor the upper shaft bearing ...
