摘要
利用生命周期评价方法分析对比再生水源热泵和燃煤锅炉在原材料生产、机组生产、运输、热量生产及废弃物处理整生命周期过程的能源消耗及SO2、总悬浮颗粒物(TSP)排放。结果表明在生产1GJ热能的情况下,再生水源热泵比燃煤锅炉节能约1GJ,减排SO20.7kg,减排大气TSP 7.2kg。热量生产阶段是耗能及污染物排放的关键环节,超过99%的能源消耗和污染排放在这一环节产生。在供暖季节,如果沈阳市现有和规划污水处理厂的再生水应用再生水源热泵替代燃煤锅炉供暖,在每年的供暖期里可为沈阳市节能11×106GJ(折合标煤37.5×104t),减排SO275.9t,减排TSP 775.4t。
The energy consumption and SO2 and TSP emission reduction of regenerated water source heat pump（RWSHP） and coal-fired boiler（CFB） during the process of life cycle stages,including the raw material production,machines manufacture,transportation,heat production,and waste disposal,were analyzed and compared using the Life Cycle Assessment（LCA） method.The results show that the RWSHP can save 1GJ heat energy and reduce 0.7kg SO2 and 7.2kg total suspended particulates（TSP） compared to CFB when producing 1GJ heat energy.Heat production is the critical stage of energy consumption and pollutants emission,and more than 99% energy consumption and pollutants emission emerge in this stage.If the regenerated water from existing and planned sewage treatment plants of Shenyang city is applied RWSHP to replace CFB heating in heating season,which can save 11×10^6GJ heat energy（converting into 3.75×10^6t standard coal） and reduce 75.9t SO2 and 775.4t TSP.
