600MW超临界CFB锅炉炉内稀相区燃烧均匀性的实炉试验研究
Field Tests on Combustion Uniformity of the Dilute Phase in a 600MW Supercritical CFB Boiler
摘要
Abstract
Field tests were carried out on a 600MW supercritical circulating fluidized bed (CFB) boiler.The flue gas components at 25m and 38m above the air distributors and at the furnace outlets were obtained and analyzed after air optimization.Results imply that the distribution trend of coal gas is determined by the distribution of coal.The distribution of flue gas composition at the secondary air elevation has an important influence on that at the fumace outlets.When the standard deviation of oxygen concentration between the front wall and rear wall at 25m above the air distributors reaches 2.8％,this value would still be 1.8％ when flue gas flowed upward to 38m above the air distributors.When the boiler run between 60％ BMCR and 75％ BMCR,the oxygen consumption per unit height (1m) is about 0.13％ in the region from 25m to 38m above the air distributor.Through the supplementary test and the regression analysis,the correlation formula for the oxygen diffusion rate in the dilute phase of the fumace is obtained.关键词
