Modeling N2O Reduction and Decomposition in a Circulating

Jul 18, 1996 · The N 2 O concentration was measured in a circulating fluidized bed boiler of commercial size. Kinetics for N 2 O reduction by char and catalytic reduction and decomposition over bed material from the combustor were determined in a laboratory fixed bed reactor. The destruction rate of N 2 O in the combustion chamber and the cyclone was calculated taking three mechanisms into account: reduction …

Cost model of industrial fluidized bed boilers (Journal

Atmospheric fluidized-bed combustion (AFBC) boilers have developed rapidly over recent years and are now offered commercially in several different configurations. SO/sub 2/ reduction levels of 90% and above have been achieved by coal-fired AFBC boilers in the industrial size category.

Using fluidized bed boilers for burning refuse-derived

Abstract. Fluidized bed combustors, a popular combustion technology for low-grade fuels, have seen little use in burning municipal solid waste. Now, a new project being built in North Carolina, is leading the way toward a new generation of economical integrated resource recovery facilities that salvage recyclables and produce energy from municipal solid waste.

Mitsubishi Power, Ltd. | Circulating Fluidized Bed (CFB

Circulating Fluidized Bed (CFB) Boilers. A circulating fluidized bed (CFB) boiler features higher gas velocity (superficial flow velocity) in the furnace (combustor) compared with a bubbling fluidized bed (BFB) boiler. The boiler activates a mixture of particles and gas to improve combustion reaction. Moreover, the fluid sand and fuel issuing out of the furnace are collected in a cyclone and recirculated …
