Project information 項(xiàng)目信息 Project name 項(xiàng)目名稱: AF belt drying by hot gas from clinker cooler 臺(tái)泥貴港廠利用窯頭廢熱烘干替代燃料項(xiàng)目 Year 購(gòu)買年份: 2021 背景介紹 As competition on cement market drives plants further development, each cement factory searches for new solutions, which could allow them to low operating cost, one of the solutions in the cement plants is reduction of primary fuel (pulverized coal) use, which increasing use of alternative fuel. 水泥行業(yè)的競(jìng)爭(zhēng)推動(dòng)了水泥工廠加速可持續(xù)發(fā)展,為了減少運(yùn)行成本,各個(gè)水泥工廠都在尋求最優(yōu)的解決方案,其中之一就是在水泥行業(yè)減少初級(jí)能源(煤粉),增加替代燃料的利用率。 圖2:臺(tái)泥貴港綠色工廠 Taiwan cement corporation (TCC) has been committed to promote energy transformation and carbon emission reduction, especially in the collaborative disposal of cement kilns and the development of green revewable energy. Alternative fuels are used to help achieve the target of "carbon peaking and carbon neutrality", while practicing the new function of "a good helper of the government and a excellent purifier of the city" as well. TCC continues to research and develop the use efficiency of alternative fuels, plant to substitute up to 80% of kiln heat demand by utilization of alternative fuels. Since many year TCC has been implementing multiple modernization projects resulting in better efficiency and automation. Use of RDF fuel is not only reduced carbon emissions during producing. but also reduce the cost of primary fuel. 臺(tái)泥集團(tuán)致力于推動(dòng)能源轉(zhuǎn)型和減碳事業(yè),特別是在水泥窯協(xié)同處置、綠色再生能源發(fā)展方面也有諸多實(shí)踐,其中通過替代燃料助力實(shí)現(xiàn)“雙碳”目標(biāo),同時(shí)也踐行“政府好幫手,城市凈化器”的新職能。臺(tái)泥集團(tuán)持續(xù)研發(fā)替代燃料的使用效率,希望實(shí)現(xiàn)工廠80%的窯爐熱能來自于替代燃料。多年前臺(tái)泥集團(tuán)就開始執(zhí)行這項(xiàng)決策,在多個(gè)現(xiàn)代化項(xiàng)目中實(shí)現(xiàn)了更高的效率和自動(dòng)化,不僅降低了生產(chǎn)中的碳排放,還減少了燃料成本。 項(xiàng)目進(jìn)展 Our customer Taiwan cement Guigang city in Guangxi Province, China, the assembly of belt dryer with hot gas piping has been complete in 25/9/2022 on time, the commissioning has been complete in 15/12/2022. 位于中國(guó)廣西的臺(tái)泥貴港工廠按時(shí)在2022年9月25日完成烘干機(jī)及熱風(fēng)管道的安裝,于2022年12月25日完成調(diào)試并順利交付。 圖3:替代燃料烘干系統(tǒng)框架結(jié)構(gòu) The high demand for alternative fuel is influencing quality deviations in deliveries, which forces TCC plant to utilize high moisture materials, to reach Alternative Fuel rate target. That’s the idea behind the installation of stela dryer. 對(duì)替代燃料的高標(biāo)準(zhǔn)要求是影響運(yùn)輸質(zhì)量的一個(gè)重要因素,迫使臺(tái)泥工廠不得不利用一些濕度更高的原料,從而達(dá)到替代燃料利用率目標(biāo)要求,這就是配置施德蘭烘干機(jī)的思路。 This drying system is integrated into the newly planned alternative fuel system which uses waste hot gas from grate cooler of kiln No.3 and No.4. 烘干系統(tǒng)集成在新建替代燃料系統(tǒng)中,利用3號(hào)和4號(hào)線篦冷機(jī)后的窯頭熱風(fēng)。 圖4:替代燃料烘干系統(tǒng)及風(fēng)管 The successfully implemented commissioning and optimization of stela alternative fuel drier capable of utilization of sawdust, bark, wood chip and waste cloth. With maximum moisture content of 55%(50 as average) and corresponding input capacity of 21 t/h of wet product. Drier’s maximum capacity is approx. 12.4 t/h with 15% water content in dried material. 成功完成調(diào)試并優(yōu)化施德蘭替代燃料烘干機(jī)能夠利用最大濕度為55%(平均50%)的木屑,樹皮以及廢紡等替代燃料,相應(yīng)的濕料喂入量為21噸/小時(shí),最大出料量濕度約15%,12.4噸/小時(shí)的干料。 戰(zhàn)略目標(biāo) First of all, the main task of build stela drying system to replace coal fuel with refuse-derived fuel (RDF) and wood chips and achieve substantial savings in clinker manufacturing costs; 首先,采用施德蘭烘干機(jī)的首要任務(wù)是采用替代燃料和木屑來取代煤炭,并大幅節(jié)省熟料生產(chǎn)成本; Secondly, improving use of alternative fuel by utilization of waste hot gases volume to obtain a higher specific calorific value of the alternative fuels and a possibility to substitute more expensive pulverized coal; 其次,通過窯頭廢熱蒸發(fā)改善替代燃料的利用,以獲得更高的替代燃料比熱值,并有可能替代更貴的煤粉; Thirdly, acquire a constant source of alternative fuels supply at competitive prices in comparison to the prices offered by other suppliers; 再次,通過提供比其它水泥工廠更具有競(jìng)爭(zhēng)力的價(jià)格來獲取替代燃料的穩(wěn)定供貨。 Finally, implement the first step to a long-term goal for TCC set up in the strategy in terms of using Alternative Fuel, i.e., achieve 50% Alternative Fuel substitution rate in heat consumption. 最后,在使用替代燃料方面,實(shí)施臺(tái)泥戰(zhàn)略中設(shè)定的長(zhǎng)期目標(biāo)第一步,即在熱耗方面實(shí)現(xiàn)50%的替代燃料利用率。 圖5:替代燃料烘干系統(tǒng)全景鳥瞰
