The variation in boiler furnace size can upset the performance drastically. Oil and gas fired units have more uniform sizes, but the coal fired units have large variation. High Ash Coals - A challenge to Power Plants - Optimisation of combustion in high ash coal fired boilers is of special interest due to the organic and inorganic mix up and
Our engineers developed an automatic stoker unit equipped with a coal hopper that held enough fuel for several days. This allowed the coal to be cleanly burned and without frequent maintenance. They then saw the need to make a hot water boiler specifically designed to burn coal and built them in multiple sizes to meet our customers’ needs.
Coal fired boiler furnace. The coal fired boiler furnace size is generally higher in volume by 20 to 35 %, depending on coal types, when compared to an oil fired boiler. The factors that increase the furnace size are many. The reactivity of coal is much lower than oil and hence need more residence time.

Coal is ground to the size of a fine grain into the boiler, mixed with air and burned in the flue gas flow. Biomass and other materials can also be added to the mixture. Coal contains mineral matter which is converted to ash during combustion. The ash is removed as bottom ash and fly ash. The bottom ash is removed at the furnace bottom.
