京津冀民用煤污染控制技术评估

Technology Assessment on Civil Coal Pollution Control in Jing-Jin-Ji Area

摘要: 为助力解决京津冀地区民用煤污染问题，研究根据民用煤污染控制技术的特点，构建了民用煤污染控制技术评价指标体系。结合当前京津冀地区民用煤污染控制技术的推广使用情况，筛选出5种待评价技术，采用多级模糊综合评价法对待评价技术开展综合评价，研究结果显示：从经济、技术、环境3方面综合考虑，5种待评技术的优选次序为：空气源热泵、燃气壁挂炉、蓄热式电采暖、太阳能 + 空气源热泵、型煤替代，评估结果与京津冀地区实际情况相符。

Abstract: The civil coal pollution in Jing-Jin-Ji area becomes a serious problem remained to be controlled and solved urgently. In order to change this terrible situation, one scientific and workable assessment indicator system is put forward coupled on the pollution characteristics of the civil coal after the field survey. In the meanwhile, it filters out five projects to be assessed finally after all civil coal pollution control technologies are investigated in study area nowadays. On this basis, five projects are evaluated comprehensively from different aspects with the fuzzy comprehensive evaluation. Results show that if it takes technology, economy and environment into account together, the preferred projects are in this order: first choice as air source heat pump, to gas hanging stove second choice, third choice as storage-type electric heating, then as air source heat pump combined with solar energy, finally as coal briquette replaced. The evaluation result is consistent to the actual situation and this assessment indicator system has a certain value for generalization. The result also reveals that under multi-constraint conditions just like technology, economy and environment, the air source heat pump is the best one. Concerning the demand of the reality, gas hanging stove and storage-type electric heating should also be considered as available technology to help solve the serious air pollution problem in study area during the heating season.
