7.1.1.2 The flue gas desulfurization process choosing
Install 6 1190t/h boiler in this issue of project, synchronous requiring construction flue gas desulfurization device, it is 0.64% to design the sulfur content of the coal, it is 0.82% to check the sulfur content of the coal. The flue gas desulfurization of this issue of project belongs to the large capacity unit desulfurization, the cigarette is large-minded, desulfurization efficiency is expected much. Consider that electricity factory director one operates coal-fired sulfur content change, the desulfurization is should be sure abundant degree, design sulfur content to design according to 0.82% in desulfurization.
目前，全世界脫硫工藝共有200多種，按其燃燒的過程可分為：燃燒前脫硫、燃燒中脫硫、燃燒后脫硫（煙氣脫硫）。
經(jīng)過幾十年不斷地探索和實踐，在火電廠上應用的脫硫工藝僅有10種左右，其中使用較多的煙氣脫硫工藝有：石灰石—石膏濕法煙氣脫硫工藝、循環(huán)流化床干法煙氣脫硫、海水脫硫、旋轉(zhuǎn)噴霧半干法煙氣脫硫工藝、爐內(nèi)噴鈣加尾部煙道增濕活化脫硫工藝、電子束煙氣脫硫工藝、以及濕式氨法煙氣脫硫工藝等。
At present, there are more than 200 kinds of desulfurization processs in the whole world, can be divided into according to its course of burning: Desulfurization, desulfurization, desulfurization after burning in burning before burning (flue gas desulfurization).
Explore and practise constantly through decades, the desulfurization process used on the thermal power plant is only about 10 kinds, among them use more flue gas desulfurization processs and have: Lime stone - Gypsum wet law flue gas desulfurization process, the circulation fluidized bed is done the flue gas desulfurization of the law, sea water desulfurization, rotate and spray the flue gas desulfurization process of the half-dried law, gush out the calcium to add the tail flue and increase and activate desulfurization process, electron beam flue gas desulfurization process, and wet type ammonia law flue gas desulfurization process,etc. wetly in the stove.
干法脫硫如爐內(nèi)噴鈣加尾部煙道增濕活化脫硫工藝、旋轉(zhuǎn)噴霧半干法脫硫工藝等均不適用于火電廠大容量機組脫硫。理由是這幾種工藝國內(nèi)目前僅應用于中、小型機組上，效率較低，在國內(nèi)外都沒有300MW單機容量的運行業(yè)績。旋轉(zhuǎn)噴霧半干法脫硫方案由于煙氣系統(tǒng)調(diào)整復雜，技術(shù)發(fā)展基本停滯，且在300MW機組上應用尚不太多，因此不予推薦。爐內(nèi)噴鈣—尾部加濕活化法經(jīng)濟上不是最好，從技術(shù)上講還會造成鍋爐效率降低約1%左右，且對鍋爐有磨損并對燃燒有影響，因而也不予推薦。
Do law desulfurization if stove gush out calcium add tail flue increase wet to activate desulfurization process, is it spray half-dried law desulfurization process,etc. Suitable for thermal power plant large capacity aircrew to rotate reason is that these kinds of processs are domestic while only applying to at present, on the small-scale aircrew, efficiency is relatively low, there is not a operation performance of 300MW unit's capacity at home and abroad. Rotate and spray the desulfurization scheme of the half-dried law and adjust the complicatedness because of the flue gas system, technology is it stay cool basically to develop, use yet not many at 300MW aircrew, so refuse to give a recommendation. Gush out the calcium in the stove - France is not economically best that the tail humidification is activated, will also speaking from the technology cause boiler efficiency to reduce about 1%, and wear and tear the boiler and to burning influence, therefore refuse to give a recommendation.
電子束法和濕式氨法煙氣脫硫工藝目前在國際上應用不多，該法受液氨來源及副產(chǎn)品銷路的限制，很難在電廠應用。電子束法由于其業(yè)績少，進口設(shè)備多、投資高、廠用電高、脫硫劑的來源及副產(chǎn)品銷售較難解決，無300MW以上機組脫硫業(yè)績，因而不予推薦采用。濕式氨法煙氣脫硫工藝國際上應用不多，該法受液氨來源的限制，國內(nèi)目前尚未有電廠建設(shè)運行。
The law of electron beam and wet type ammonia law flue gas desulfurization process are not used more in the world at present, this law is restricted by the ammonia source of the liquid and by product sale, difficult in power plant application. Electron beam law because performance their little, import equipment more, invest in high, factory with electricity high, source and by product, desulfurization of pharmaceutical sell difficult to solve, have 300MW above aircrew desulfurization performance, therefore will not recommendation adopt. The wet type ammonia law flue gas desulfurization process is not used more in the world, this law is restricted by ammonia source of the liquid, has not had construction of power plant that has run domestically yet at present.
煙氣循環(huán)流化床干法脫硫適用于中小機組脫硫，其脫硫效率可達85～90％，但隨著機組容量的增大，吸收劑耗量會隨之增大，運行成本較高。從電廠的實際情況看，由于機組容量大，要求的脫硫效率相對較高，該方法也無法滿足排放要求。此外干法脫硫吸收劑一般為CaO，脫硫過程采用的Ca/S比較大，吸收劑耗量大，導致脫硫劑成本高，脫硫廢渣也相應大，且廢渣利用價值低。
The circulation fluidized bed of flue gas is done France's desulfurization applies to the desulfurization of the medium and small unit, its desulfurization efficiency can be up to 85- 90, but with increase, unit of capacity, absorbent person who dawdle can thereupon increase, relatively high operating cost have. By the look of actual conditions of the power plant, because the unit is large in capacity, the desulfurization efficiency required is relatively high, this method is unable to meet the requirements of discharging. In addition do the law the desulfurization absorbent is generally CaO, Ca/S that the desulfurization course adopts is bigger, the absorbent is big in dawdling amount, it is with high costs to cause the desulfurization pharmaceutical, the desulfurization waste residue is corresponding and big too, and waste residue value is low.
