,組分,單位,濕態(tài)數(shù)據(jù),干態(tài)數(shù)據(jù)

,N2,%,14.95,16.43

,CO2,%,14.21,15.62

,SO2,%,0.78,0.86

,H2O,%,9.00,0.00

,O2,%,6.76,6.76

,干煙氣量：,1323631,Nm3/h,

,煙氣相對(duì)濕度=,水蒸氣體積/干煙氣體積,,

,=,9/(100-9),,

,=,0.0989,,

,干煙氣中SO2和CO2體積份額=,(0.85+15.61)/100,,

,=,0.1647,,

,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,

,((6.97+2.90×0.1647)×132+(10710+8.51×132)×0.0989)×1323631,,,

,=,2850340333,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,

,"設(shè)反應(yīng)器出口煙氣的相對(duì)濕度為h1,則",,,

,((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,,

,=,40.2496,t/h,

,2）不脫硫時(shí)耗水,,,

,反應(yīng)器進(jìn)口溫度℃,反應(yīng)器出口溫度℃,,

,132,140,,

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

,"設(shè)反應(yīng)器出口煙氣的相對(duì)濕度為h2,則",,,

,((6.97+2.90*0.1647)*140+(10710+8.51*140)*h2)*1323631=2850340333.4467,,,

,求得：h1=,0.0933,kmolH2O/kmol干氣,

,所以脫硫噴水量為=,（0.0933-0.0989）*1323631/22.4*18/100
