【摘要】：水泥熟料是主要的CO_2排放源,其排放系數(shù)受原料種類和品質(zhì)、生產(chǎn)工藝、生產(chǎn)規(guī)模等多種因素的影響。分析中國各地區(qū)熟料排放的差異性、減排潛力和策略選擇,可以為區(qū)域降低熟料排放的方法和政策選擇提供決策支持。本文以全國22省市中182條新型干法生產(chǎn)線和75條立窯生產(chǎn)線為樣本,對中國水泥熟料排放系數(shù)差異性進(jìn)行了分析,結(jié)論認(rèn)為:(1)生產(chǎn)工藝的排放差異:立窯熟料排放系數(shù)高于新型干法;(2)生產(chǎn)規(guī)模的差異:隨著生產(chǎn)規(guī)模的增加,燃料排放、電力排放呈現(xiàn)降低的趨勢,而工藝排放則不受此影響;(3)熟料排放系數(shù)呈現(xiàn)從東部沿海向西部內(nèi)陸逐漸增加的態(tài)勢,從熟料排放系數(shù)構(gòu)成來看,熟料高M(jìn)gO含量將導(dǎo)致高的工藝排放,原料替代減排主要集中在鋼鐵和磷生產(chǎn)集中的華北和西南地區(qū);高寒區(qū)域和西南地區(qū)也是高能源強(qiáng)度和高燃料排放的區(qū)域。論文進(jìn)一步分析了工藝替代、規(guī)模生產(chǎn)和原料替代三種方式在調(diào)研省區(qū)的減排潛力,根據(jù)各種方法減排量所占份額,將驅(qū)動區(qū)域減排的方式選擇歸納為單因素、雙因素和均衡發(fā)展三種類型。文章認(rèn)為調(diào)研區(qū)域應(yīng)根據(jù)三種方式的份額,有目的地選擇減排方式和設(shè)計相應(yīng)的減排政策。
[Abstract]:Cement clinker is the main CO_2 emission source, and its emission coefficient is affected by various factors, such as the type and quality of raw material, production process, production scale, etc. The differences of clinker emissions, the potential of emission reduction and the selection of strategies are analyzed. In this paper, 182 new dry process production lines and 75 shaft kiln production lines in 22 provinces and cities of China are taken as samples to analyze the difference of cement clinker discharge coefficient in China. The conclusions are as follows: (1) the difference of production process emissions: the discharge coefficient of clinker in shaft kiln is higher than that of the new dry process (2) the scale of production is different: with the increase of production scale, the emission of fuel and electric power is decreasing. However, the discharge coefficient of clinker increased gradually from the east coast to the inland of the west. According to the composition of the clinker discharge coefficient, the high MgO content of clinker will lead to high process discharge. The emission reduction of feedstock substitution is mainly concentrated in North and Southwest China, where iron and steel and phosphorus production are concentrated; the high cold region and southwest region are also high energy intensity and high fuel emission regions. According to the share of emission reduction amount of various methods, the way of driving regional emission reduction is summed up as a single factor according to the scale production and feedstock substitution in the study of the potential of emission reduction in the provinces and regions. The paper points out that the research area should choose the emission reduction mode and design the corresponding emission reduction policy according to the share of the three ways.
