,摩爾基準(zhǔn)時(shí)的焓：,,,

,計(jì)算公式：,,,

,i=(6.97+2.90x)t+(10710+8.51t)H,,,

,i……=焓（kcal/kmol干氣）,,,

,t……=煙氣溫度（℃）,,,

,x……=干氣中CO2，SO2，CH4等的比率（CO2，SO2，CH4等，kmol/kmol干氣）,,,

,H……=摩爾濕度（kmolH2O/kmol干氣）,,,

,反應(yīng)器進(jìn)口煙氣焓值：,,,

,I1=((6.97+2.90x)t+(10710+8.51t)*H)*1323631,,kcal/kmol*Nm3/h,

,為簡(jiǎn)化計(jì)算，設(shè)反應(yīng)器為絕熱增濕過(guò)程：,,,

,所以反應(yīng)器出口煙氣焓值=,2850340333,kcal/kmol*Nm3/h,

,((6.97+2.90×0.1647)×80+(10710+8.51×80)×h1)×1323631=2850340333.4467,,,

,求得：h1=,0.1367,kmolH2O/kmol干氣,

,所以脫硫噴水量為=,（0.1367-0.0989）*1323631/22.4*18/1000,,
