Coal Firing Nozzles
The coal nozzle in a boiler furnace can be a significant factor in the efficient operation of the boiler system. Selecting the proper nozzle is important to ensure optimal fuel combustion and prevent problems such as slagging and fouling. According to Beckett Corporation, the fuel supplied to the nozzle must be clean and air-free, and the pump pressure should be set correctly.
It is important to note that coal-fired boilers can be subject to slagging and fouling issues.
These issues can be caused by a range of factors, including low furnace excess oxygen, extreme stratifications of the FEGT flue gas lanes, high primary airflows, and more.
A proper understanding of these common causes can help identify and address slagging and fouling problems in coal-fired boilers.
