Fluidization technology has evolved significantly over the past 100 years, following the development by Winkler in 1922 [1] of the first prototype for this modern concept. Since then, fluidization has found widespread applications in process industries, with coal/biomass combustion or gasification (, Refs.

WhatsApp: +86 18838072829The Winkler process for the gasification of coal has been in successful commercial operation since the middle 1920s. In the fluid bed of the gasifier coal reacts with a mixture of air or oxygen and steam. The gas leaving the gasifier is only a mixture of H2, CO, CO2, N2, and CH4. The basic process is discussed along with the heat and material balances and the advantages of the Winkler system.
