某锅炉改造项目的电锅炉供暖系统的经济性分析

Economic analysis of electric boiler heating system for a boiler reconstruction project

为了分析张石高速公路某收费站锅炉房改造项目的电锅炉供暖系统的经济性,建立了寿命周期成本计算模型,以寿命周期成本最小为决策准则,优选电锅炉供暖方案。结合项目实际情况,对电锅炉水蓄热系统和电锅炉固体蓄热系统进行分析,结果表明电锅炉水蓄热系统的初投资比电锅炉固体蓄热系统的初投资小的多,前者的寿命周期成本略小于后者的寿命周期成本,宜采用电锅炉水蓄热系统供暖。

In order to analyze the economy of the electric boiler heating system of the boiler room renovation project of a toll station in Zhang-Shi expressway,a life cycle cost calculation model is established. The minimum cost of life cycle is the decision criterion,and the electric boiler heating scheme is preferred. According to the actual situation of the project,the electric boiler boiler heat storage system and the electric boiler thermal storage system are analyzed. The results show that the initial investment of the electric boiler heat storage system is much smaller than the initial investment of the thermal storage system of the electric boiler. Cycle cost is slightly less than the latter＇s life cycle cost,should use electric boiler water storage system heating.
