分布式供暖的经济分析——以西安思源学院四号锅炉房供暖区为例

Economic Analysis of Distributed Heating—Taking the Heating Area of the No.4 Boiler Room of Xi’an Siyuan University as an Example

摘要: 西安思源学院四号锅炉房供暖区采用分布式供暖，工程总支出为370.125万元。其中87%为燃气建设费用，13%为燃气建设均摊费。燃气建设费用主要有锅炉设备与安装费(86%)、锅炉房土建费(10%)和报警器费用(4%)。计算结果表明：分布式供暖的每年收益约为37.2万元；节约能源、节约人工和节能减碳三项收益分别占全年总收益的44.28%、51.63%和4.09%，需要10年才能收回成本。天然气价格和二氧化碳排放费用的涨价趋势对分布式供暖的前景影响很大，应尽早做分布式供暖。

Abstract: The heating area of the No.4 boiler room of Xi’an Siyuan University adopts distributed heating, and the total expenditure of the project is 3,701,250 yuan, of them, 87% for gas construction costs, 13% for the cost of sharing gas construction equality. Gas construction costs mainly include boiler equipment and installation cost (86%), and boiler room civil cost (10%) and alarm cost (4%). The calculation results show that annual revenue for distributed heating is about 372,000 yuan. The three proceeds of energy saving, labor saving, and carbon dioxide reduction accounted, respective-ly, for 44.28%, 51.63%, and 4.09% of the total annual income; it will take 10 years to recover costs. Price increasing of natural gas and CO2 emissions fees has big impacts on the prospects of distrib-uted heating. The rising trend of natural gas price and carbon dioxide emission cost has a great im-pact on the prospect of distributed heating, so distributed heating should be done as soon as possi-ble.
