Classification of coal fired boiler systems
Our company's coal fired boilers are mainly divided into two types:
1. Circulating fluidized bed (CFB) boilers: wide fuel adaptability, thermal efficiency as high as 89% and low NOx emission, which are comparable to gas boilers;
2. Chain grate boilers: the thermal efficiency can reach up to 82%, low investment, convenient operation and wide load adjustment range.
Both of these are widely applied coal fired boiler types.
