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).
Coal boilers are commonly used to heat water and create steam for energy production. Coal-fired boiler efficiency can often provide lower operating costs in comparison to other fossil fuels – almost 75% less than oil or natural gas. Coal, when properly handled and combusted, is one of the cleanest fossil fuels available today.
Riley Power recently participated in field testing on a wall fired boiler rated at 1,779,000 lb/hr of main steam flow. The boiler is an opposed fired design with two (2) levels of burners on both the front and rear walls. The natural gas supply system to the boiler utilized a single flow control valve for all the burners.

Clinkers resemble volcanic ash and lava. They occur in the high-temperature furnace area of the boiler. Clinkers form as a result of interaction among coal quality, boiler design and boiler operation. Coal boilers draw their combustion air from the bottom, up through the combustion grate.
I have a Trianco coal fired boiler which works well most of time. However in very strong, prolonged winds ie force 6 or above it has overheated the complete system to boiling point. On shutting it down, including the fan, it continues to burn fiercely. The only way to stop it is to declinker to remove any embers.
