摘　　要：根据某热电厂大比例掺烧烟煤存在的锅炉水冷壁超温、高温腐蚀等实际问题,通过数值模拟对燃烧器不同的相对位置及偏转角度对炉膛内速度场、温度场的影响进行探究,为解决锅炉水冷壁超温的问题提供理论依据。Based on the actual problems of boiler water-cooled wall overheating and high-temperature corrosion caused by the large-scale blending of bituminous coal in the a certain Thermal Power Plant,the influence of different relative positions and deflection angles of burners on the velocity and temperature fields in the furnace is explored through numerical simulation,providing a theoretical basis for solving the problem of boiler water-cooled wall overheating.
