Through the flue gas and air characteristic analysis in supercharged boiler,the results showed that the value of parameters would increase with the increase of fuel consumption.And volume heat load of the furnace, fuel consumption, heat change between flue gas and convective heating surface and evaporation value would increase with the increase of compression ratio.The heat calculation would be different because of dissimilar thermal calculation in the turbo-compressor when the boiler load was changed.As the boiler load increased,heat loss in the turbo-compressor would increase and the efficiency of the boiler would decrease.The results of the boiler start-up simulation showed that the time of start-up would decrease with the increase of flue consumption ,but instantaneous pressure amplitude would increase.Steam water"s dymamic diversification would be more complex than flue gas"s,and dynamic characters of their parameters would be changed due to different boiler load and disturbance variable,which was shown by results of the simulation when boiler load was changed.

通过分析增压锅炉内的空气、烟气参数特性，发现随着锅炉负荷的增加，空气和烟气的各项参数值都相应的增加；炉膛容积热负荷、锅炉的燃料负荷随着增压比的提高成比例增加；随着增压比的增大，烟气与对流受热面的换热增加，蒸发量随之增加；由于涡轮增压机组在不同负荷下的热力计算不同而造成增压锅炉在不同负荷下的热平衡计算的不同；锅炉增压机组的总的热损失随着锅炉负荷的增加而增加，而增压锅炉的热效率随着锅炉负荷的增加而减少；锅炉启动模拟仿真结果中发现，锅炉启动时燃料量增加，锅炉的启动时间就会减少，但是瞬时升压速度会增加；而动态负荷变化模拟仿真结果中发现，锅炉汽水侧的变化相比烟气侧更为复杂，且在不同负荷和不同扰动量下，烟气侧和汽水侧的重要参数动态特性是不同的。
