Coal, when properly handled and combusted, is one of the cleanest fossil fuels available today.
Pulverized coal fired boilers the total losses account to about 12 to 14 %. Roughly 50% of the losses can be tuned to the optimum and the other 50 % is governed by fuel properties like hydrogen in fuel, moisture in fuel and ambient air conditions. The main two losses in boiler that can be tuned by operator are carbon loss and dry gas loss.

The Importance of Boiler Maintenance 2017-11-14 15:08:41. Industrial boilers play a crucial role in energy production and other industrial processes. Boilers are very valuable assets requiring routine maintenance and inspection. There are several reasons why good industrial boiler maintenance is so important.
Coal-fired boilers are mainly operated at either subcritical or supercritical conditions. From a thermo-physics perspective, two phase mixtures of water and steam are replaced by a single supercritical fluid when the boiler pressure increases above the critical pressure of 22.12 MPa and the corresponding saturation temperature of 374 °C (Shen and Cheng, 2004).
Most pulverized-coal-fired boilers have at least one extra pulverizer to allow routine maintenance to be performed without reducing the boiler load. Selection of the number of pulverizers needed to handle the desired load is based on the heat content and grindability of the coal because these charac- teristics affect pulverizer capacity.
