How to Run a Coal Fired Boiler at the Best Efficiency

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.

Pulverised Coal Combustion an overview ScienceDirect

Pulverised coal combustion in large utility boilers can result in the production of significant amounts of oxides of nitrogen (NOx principally NO in this type of plant). Although some of this NOx is formed from nitrogen in the combustion air, the principal source of NOx is generally the nitrogen contained in the coal itself since the latter is available in more reactive form.
