摘　　要：应用直流锅炉汽压微分关系式,针对某1 000MW直流锅炉,定量分析了各影响因子在典型负荷下对汽压的影响,并绘制了影响因子强度图谱。发现输入热量、燃煤量、锅炉效率、给水焓、给水量对汽压的影响最大,而其他因素影响相对较小。所得结论可为超临界直流锅炉的控制研究提供理论依据及指导作用。Main Stream pressure of supercritical boiler differential relation is used to calcula- tion a 1 000 MW unit. Quantitative analysis the influence of different impact factor at differ- ent load. Finding that, heat input, coal combustion quantity, boiler efficiency, feed water en- thalpy and feed water quantity has a great influence on Main Stream pressure, meanwhile other factor affect much smaller. Conclusions get from this passage can be a guide line of su- percritical boiler control and operation.
