富氧燃烧循环流化床锅炉炉内传热特性
Heat Transfer Characteristic in Oxy-fuel Circulating Fluidized Bed Boiler
摘要
Abstract
The heat transfer in oxy-fuel circulating fluidized bed boiler (CFBB) was investigated. A model which considers the influence of gases radiation on heat transfer coefficient was set. Take a 440t/h CFBB for example, the heat transfer in furnace was calculated and the results were compared with air-fired CFBB. The model shows the heat transfer coefficient is not be changed greatly in oxy-fuel combustion, because the heat transfer is dominated by the effect of particles, not depend on gases composition. The concept design of oxy-fuel CFBB was done at 30%, 50%, and 70% O2 concentration. It was found the higher concentration of oxygen the more necessary to set an external heat exchanger to keep a normal operation of the furnace.关键词
