h 汽包水位偏离正常水位的值，mm; P对应汽包水位的差压值，mmH2O; s饱和蒸汽的密度，kg*103=/m3;w饱和水的密度，kg*103=/m3; a参比水柱的密度，kg*103=/m3;上式中，H、A和B都是常数；w、s是汽压的函数，在特定汽压下均为定值；平衡容器内汽水的密度a与其散热条件和环境温度有关。在锅炉启动过程中，水温略有升高，压力也同时升高，这两方面的变化对a的影响基本上抵消，可以近似认为a是恒值。根据（1）有如下：h = A-P*/(w-s)+H*(a-w)/ (w-s) =A-(P-H*(a-w)* /(w-s) (3)令F1(X)=(a-w)；F2(X)=1/(w-s)；二、补偿逻辑框图：PXhHXF1(X)F2(X)AP三、F1(X)/F2(X)参数表：单室平衡容器汽包压力(MPa)F1（x）F2（x）001.010.1005749611.14028116120.1364474431.1958769930.163784021.24393479840.187009151.2893729560.2270438271.37975473780.2627263991.476356555100.2964214751.585724387120.3296781491.716322335140.3636855731.881343919160.4001311122.107555006180.4418569032.460268331区域为：区间4;
