掺烧污泥煤粉锅炉燃烧特性的数值模拟
Co-combustion of sludge in a 100 MW unit coal-fired boiler:numerical simulation
摘要
Abstract
Numerical simulation using single-and double-mixture-fraction /PDF (Probability Density Function) transport model was carried out to evaluate the characteristics of coal burning alone and with domestic sludge on a 420 t/h tangentially coal-fired boiler.The flow,combustion and NOx emission properties were investigated.The sim-ulation results were consistent with the field test under the same working condition,when the coal was burned alone and the load is 70% and 1 00%.Under 1 00% load condition,the NOx emission reduced after co-combustion.With the increasing mass ratio of sludge,the burn out rate of coal decreased slightly.Temperature distribution and flue gas composition distribution in the furnace were roughly the same.All these above indicated that the co-combustion had little influence on characteristics of flow,combustion and NOx emission of this boiler.关键词
