Chapter 1 Coal-fired Power Generation and Circulating

The high combustion temperatures in pulverised coal fired boilers can be the cause of slagging and fouling problems in the furnace, superheater and reheater sections depending on the coal quality. Therefore regular soot blowing is required to keep these areas clean. On the other hand, combustion temperature in CFBC boilers is low, around 900°C, which reduces slagging or fouling problems.
