摘　　要：在炉膛压力变化情况下,对增压锅炉相关热力计算参数的变化规律进行了系统分析,并针对某型增压锅炉进行了实例计算,得出了其烟气流速及炉膛黑度随压力的变化曲线。增压锅炉炉膛压力升高时,其容积热负荷和炉膛黑度将增大,炉膛出口烟温及线性流速等将减小,而烟气的对流换热系数等参数不变。Under the condition of the furnace pressure undergoing a change,systematically analyzed was the variation regularity governing the relevant thermal calculation parameters of a turbocharged boiler.A case calculation was performed of a certain type of turbocharged boiler and the curves of its flue gas flow velocities and furnace blackness changing with its furnace pressure were obtained.When its furnace pressure increases,its volumetric thermal load and furnace blackness will also increase.The flue gas temper...
