民用清洁煤技术的定量评价与筛选

选用合适的民用清洁煤技术是提高居民生活用煤能源利用效率、减少环境污染的重要途径之一，本文利用笔者提出的清洁煤技术定量评价方法对民用清洁煤技术进行了定量评价与筛选，评价结果表明，在标准状态下各种民用适用清洁煤技术的单位综合成本分别为选煤48元/GJ，民用型煤45.73元/GJ，炼焦制气28.53元/GJ，加压气化联产甲醇54.73元/GJ，加压气化联产油蜡50.71元/GJ，两段炉气化88.66元/GJ，直立炉气化38.84元/GJ，其中炼焦制气是单位综合成本最小的民用清洁煤技术．敏感度分析表明，煤气化将是民用清洁煤技术的主要发展方向

Quantitative assessing and screening on clean coal technologies suitable for resident

It is an mportant route to increase efficiency and reduce pollutants on coal using for resident that clean coaltechnologies suitable for resident is to be chosen and used. In this paper, a quantitative assessing method on clean coaltechnologies us is used to assess and screen clean coal technologies suitable for resident. Integrated cost for unit energyproduction on various clean coal technologies suitable for resident is coal cleaning 48.37 yuan/GJ,coal molding for resident 45.37 yuan /GJ,coking 28.53 yuan/GJ,coal pressurized gasification combined with methanol 54.73 yuan/GJ,coalpressurized gasification combined with oil and 50.71 yuan/GJ,coal two-segment stove gasification 88.66 yuan/GJ,erectionstove gasification 38.84 yuan /GJ. Integrated cost for unit energy production on coking is the least. Sensitivity analysis oncoal sulfur and charge for SO2 shows coal gasification is the main development direction for clean coal technologiessurtable for resident.
