1. Many kinds of fuel are applicable, including high quality coal as well as inferior coal with low volatile and high ash.
2. Because of high combustion efficiency and full gas and solid state mixture, uncompletely burnt large particles can be circulated to the furnace for continuous burning.
3. The boiler has efficient desulfurating, low temperature combustion, and low discharge of nitrogen oxide.
4. Load can be adjusted in a wide range with a high speed.
5. By comparison with pulverized coal fired industrial boiler, the fuel preprocessing system is simple, which is easy to Implement comprehensive utilization of ash.
