OPTIMIZATION OF COMBUSTION IN PULVERIZED COAL FIRED BOILER
the efficiency of existing coal fired plants. Operation of non-optimized boiler can lead to reduced boiler efficiency, increased excess air requirements, delayed combustion, increased heat loss, high CO and NOx emissions and many other. Optimization of combustion in pulverized coal fired boiler is very important today for every thermal power plant.

NOx Emissions control for coal-fired boilers
A pulverized coal-fired boiler is an industrial or utility boiler that generates thermal energy by burning pulverized coal (also known as powdered coal or since it is as fine as face powder in cosmetic makeup) that is blown into the firebox. Coal is one of the most vital and abundant energy sources in the world.

What Causes Clinkers in Coal Fired Boilers? | Hunker
Clinkers have been a recurring problem in all coal-fired boilers for as long as humans have operated coal boilers. Clinkers occur in small stoves used for heating a home and in giant commercial/industrial boilers. Clinkers, also known as slag, consist of the noncombustible elements and minerals found in coal that melt and fuse together as lumpy ashes from coal combustion. Boiler operators consider clinkers to be miserable stuff.
