Pulverised Coal - an overview | ScienceDirect Topi

Pulverized-coal firing is especially suitable for very large boilers and cement kilns. A wide range of coals can be burnt, but coal preparation and gas cleaning are major cost items. 70% < 75 μm is required for bituminous coals, 80% for anthracite. Coal dried with air at 250–350°C for milling in low-, medium- or high-speed mills.

How to Run a Coal Fired Boiler at the Best Efficien

Boiler efficiency is mainly depended on the amount of losses in the system. In high capacity pulverized coal fired boilers the total losses account to about 12 to 14%. Roughly 50% of the losses are governed by fuel properties like hydrogen in fuel, moisture in fuel and ambient air conditions. The other 50% losses are carbon loss and dry gas loss.

Coal Burners in Large Thermal Power Plan

Coal burning in large power plant boilers takes place in different ways. By pulverizing to a fine powder and being piped into different burners placed in the furnace of the boiler. Large capacity power plant boilers use this method. By circulating fluidized bed where large coal particles spread on to the bottom of the furnace and the air pressure from the bottom keeps it floating to give good
