摘要:
介绍了山东新汶矿业集团在所辖的两个煤矿井进行的地下煤炭气化工艺流程、气化气态产物的主要成分和热值测定结果.地下煤炭气化的气态产物经过净化后,除了供给矿区25000户居民作为家庭用燃料以外,还作为内燃机发电机组的发电燃料,内燃机发电机组的单机额定发电功率为400kW.实际运行结果表明,机组的发电燃料单耗由于燃烧控制系统不能保证燃料充分燃烧造成气缸积炭而增加了15%～20%.为此提出了地下煤炭气化气体产物有效的净化流程,并对发电机组的运行参数、机组出力的影响规律和地下煤炭气化内燃机发电机组的运行特性进行了研究,得出了地下煤炭气化的气态气化产物的收到基低热值在5.72～16.161MJ/Nm3范围内,气缸正常运行时的壁温范围为370～420℃.地下煤炭气化内燃机发电机组的正常连续运行时间超过4500h,为地下煤炭气化发电机组的推广应用提供了可靠的技术依据.
Abstract:
Th is paper introduces the techn ica l flow o f the underground coa l gasification( UCG), the ma in com ponents of the gas produc ts and the ir heat va lues measured in UCG wh ich is carr ied out by two coa lm ines belong ing to Shandong X inw en Coa lm inesG roup. Not on ly are the c leaned UCG gas products used as househo ld fue l for the 25 000 families liv ing in them in ing area, but a lso as fue l fo r pow er generation of the genera to r set w ith the in ternal combustion eng inewhose sing le rated pow er is 400 kW. Practical operating results indicate that the fue l consumption increases by 15% ~ 20% due to carbon deposit caused by insufficien t combustion in the cy linders. H ence, th is paper puts fo rw ard an effective c lean ing flow fo rUCG, studies the im pac ts o f the operating pa rame ters o f the generator set on its ou tput and the opera ting features of theUCG pow er gene ration system s. A conclusion is draw n that theUCG interna l combustion eng ine generators can run over 4 500 hours continuously when the low hea t-value in rece iv ed standard, Qarl of the UCG gas products, rang es from 5. 72M J/Nm3 to 16. 161M J/Nm3 and the tem pe ra ture on the cy linder under regular operating s ituation v aries from 370℃to 420℃ . And a re liab le technical support is prov ided for the gene ra liza tion and application o f the g enerator se t of the underground coal gasification.
