7.1.1.2 烟气脱硫工艺选择
本期工程安装6台1190t/h锅炉，同步配套建设烟气脱硫装置，设计煤种含硫量为0.64%，校核煤种含硫量为0.82%。本期工程烟气脱硫属大容量机组脱硫，烟气量大，脱硫效率要求高。考虑到电厂长期运行燃煤含硫量变化，脱硫应有一定裕度，脱硫设计含硫量按0.82%设计。
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，全世界脱硫工艺共有200多种，按其燃烧的过程可分为：燃烧前脱硫、燃烧中脱硫、燃烧后脱硫（烟气脱硫）。
经过几十年不断地探索和实践，在火电厂上应用的脱硫工艺仅有10种左右，其中使用较多的烟气脱硫工艺有：石灰石—石膏湿法烟气脱硫工艺、循环流化床干法烟气脱硫、海水脱硫、旋转喷雾半干法烟气脱硫工艺、炉内喷钙加尾部烟道增湿活化脱硫工艺、电子束烟气脱硫工艺、以及湿式氨法烟气脱硫工艺等。
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.
干法脱硫如炉内喷钙加尾部烟道增湿活化脱硫工艺、旋转喷雾半干法脱硫工艺等均不适用于火电厂大容量机组脱硫。理由是这几种工艺国内目前仅应用于中、小型机组上，效率较低，在国内外都没有300MW单机容量的运行业绩。旋转喷雾半干法脱硫方案由于烟气系统调整复杂，技术发展基本停滞，且在300MW机组上应用尚不太多，因此不予推荐。炉内喷钙—尾部加湿活化法经济上不是最好，从技术上讲还会造成锅炉效率降低约1%左右，且对锅炉有磨损并对燃烧有影响，因而也不予推荐。
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.
电子束法和湿式氨法烟气脱硫工艺目前在国际上应用不多，该法受液氨来源及副产品销路的限制，很难在电厂应用。电子束法由于其业绩少，进口设备多、投资高、厂用电高、脱硫剂的来源及副产品销售较难解决，无300MW以上机组脱硫业绩，因而不予推荐采用。湿式氨法烟气脱硫工艺国际上应用不多，该法受液氨来源的限制，国内目前尚未有电厂建设运行。
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.
烟气循环流化床干法脱硫适用于中小机组脱硫，其脱硫效率可达85～90％，但随着机组容量的增大，吸收剂耗量会随之增大，运行成本较高。从电厂的实际情况看，由于机组容量大，要求的脱硫效率相对较高，该方法也无法满足排放要求。此外干法脱硫吸收剂一般为CaO，脱硫过程采用的Ca/S比较大，吸收剂耗量大，导致脱硫剂成本高，脱硫废渣也相应大，且废渣利用价值低。
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.
据资料介绍，该脱硫技术可配锅炉容量为5～300MW，脱硫效率为80～90%，国外有170MW燃煤电厂的业绩，国内有广州恒运电厂210MW燃煤电厂已投运，华能榆社电厂二期2×300MW已投运，连云港电厂2×300MW已投运。目前国内采用烟气循环流化床脱硫最大机组容量为华能邯峰电厂一期2×660MW机组烟气脱硫技改工程。邯峰一期2×660MW机组烟气脱硫装置在2008年12月10日已顺利通过168小时试运行，且脱硫率稳定在90％以上，说明CFB-FGD工艺在“单塔处理大烟气量”以及“一炉两塔”获得成功的应用。

In recent years, with the updating and simplifying of this processing system, the operation and maintenance is becoming more and more convenient and the manufacturing cost is drop further. This process has more successful performance in China.
石灰石—石膏湿法烟气脱硫工艺是目前世界上应用最广泛、技术最为成熟的脱硫技术。该工艺采用石灰石作为脱硫吸收剂，石灰石磨制后形成石灰石浆液，利用石灰石浆液吸收烟气中的SO2。该系统脱硫效率可达到95%以上，是目前国内外300MW以上的燃煤机组中应用最为成熟的烟气脱硫工艺系统，国外已有单台1200MW机组的运行业绩，国内已有单台1000MW机组的运行业绩，其吸收剂石灰石价廉易得及副产品石膏能够综合利用。因此从技术成熟可靠、吸收剂（石灰石）价廉易得、副产品能够综合利用等方面考虑，对于本工程1190t/h大容量锅炉烟气脱硫，推荐采用石灰石—石膏湿法烟气脱硫工艺。
The Energy Center FGD Process is the most extensive and desulfurization technology in the world at present. This process applies the lime stone as the desulfurization absorbent, obtains the lime stone fluid after milling process, and utilizes lime stone fluid to absorb SO2 in the flue gas. The desulfurization efficiency of this system may reach 95% above. It is the most sophisticated flue gas desulfurization process system in the coal-fired300MW above in the world at present. There already has the single operation performance of 1200MW unit abroad, and has the single operation performance of 1000MW unit in China. The absorbent lime stone is so cheap and easily available, and the by-product gypsum can be utilized synthetically. Therefore, considering the benefits of the sophisticated and reliable technology, absorbent (lime stone) is cheap and easily available, and the by-product can be synthetically utilized, as for the 1190t/h large capacity boiler flue gas desulfurization of this project, we recommend to apply the Energy Center FGD Process.
