Measurement of O2 Concentration in Exhaust Gases from Pulverize

Unlike oil, coal produces a large quantity of ashes when it is burned, necessitating pulverized coal-fired boilers to be equipped with an ash removal system such as a cyclone. Exhaust gases from these boilers contain a large quantity of dust (10 to 30 g/Nm³) and flow very fast as the result of the large volume of air being blown into the boiler.

Pulverised Coal - an overview | ScienceDirect Topi

Pulverized coal firing is the method of choice for large industrial boilers (e.g., > 250,000 lb steam/h) and coal-fired electric utility generators since pulverized coal-fired units can be constructed to very large sizes (i.e., up to 1300 MW or 9.5 million lb steam/h) and unlike stoker units, where some designs have coal restrictions, can accommodate virtually any coal with proper

Why Pulverized Coal is Used in a Power Pla

These unburned carbon particles go out with ash. This is a loss and could be in the range of 5 % or greater in the older grate-fired combustion. Modern boilers powder the coal to a very fine dust so that while burning, it is almost like a fluid stream. The size of the coal particles is in the range of 75 microns.
