Oxy-CFB combustion technology for use in power

2020-5-1 · Oxy-combustion of sub-bituminous coal demonstrated the most stable combustion. Because oxy-combustion involves existence of a high CO 2 partial pressure within the furnace, the CO concentration was controlled at 40 ppm or less, despite its increase being higher compared to that observed in air combustion, thereby achieving a combustion

A novel suspension-floating-circulating fluidized

A novel suspension-floating-circulating fluidized combustion technology is proposed for burning coal slurry fuel in traditional circulating fluidized bed boilers (CFBB). This technology can solve some existing problems in large-capacity CFBB burning coal slurry. The principles of the suspension-floating-circulating fluidized combustion technology were introduced in detail in this paper.
