摘要
Abstract
The influence of gas rate and circulation rate to particles contain rate in the cold riser and the thermal industrial circulating fluidized bed were investigated.The experimental results show under cold experimental condition,circulation rate is lower(20-250 kg/(m2 · s)),particles contain rate is lower than 0.12,particles contain rate decreases with the gas rate at the same circulation rate;under hot experimental condition,circulation rate is higher(200-450 kg/(m2 · s)),when gas rate is in the range of 10.50-13.20 m/s,particles contain rate is lower than 0.35,also get a associated formula about particle contain rate and the maximum particle contain rate under cold and hot experimental condition.Particles contain rate of hot experiment is greater than that of cold experiment under the condition of the same gas rate and circulation rate.关键词
