Combustion in fluidized beds

摘要: Circulating fluidized-bed (CFB) combustion systems have become popular since the late 1970s, and, given current level of activity in area,it is clear that this technology has a stable future boiler market. For standard coal applications, competition fierce with mature pulverized-fuel-based (PF) set to maintain strong profile. CFB systems, however, can be more cost effective than PF when emission control considered, as matures, it expected an ever-increasing proportion installations will utilize concept. advantages low-grade fuels such waste and biomass. In conventional bubbling beds, often demonstrates superior carbon burn-out efficiency. The key technique hydrodynamic behavior fluidized bed. This article begins description fundamental fluid dynamic system. followed by examination process environment discussion status major technologies.
