【導(dǎo)讀】塊狀原料煤一般用固定床氣化爐。下向上逆流通過。燥，產(chǎn)生焦油和酚混在煤氣中，使凈化困難；轉(zhuǎn)動爐箅；操作周期短、維修費用大。豐富運行經(jīng)驗、適用。混合燃料-垃圾衍生燃料，細(xì)煤粉宜用沸騰床氣化。爐子構(gòu)造簡單、投資少?；曳譃?0%的煤也能運行。熔點，灰中含C量高。高溫法壓力提高到1MPa，很細(xì)的粉塵煤用氣流床氣化。用加壓氣化法提高生產(chǎn)能力。因為必須采用很高。干法固態(tài)顆粒連續(xù)清除。二段式設(shè)計，提高了氣體的熱含量和能效，也提升了氣化。也能處理低反應(yīng)能力的石油焦給料。根據(jù)美國能源技術(shù)實驗室于2007年8月做出的獨立。由此報告可以看出，E-Gas技術(shù)在投。資，效率，操作成本上實現(xiàn)了非常優(yōu)化的平衡。
