基于全寿命周期成本的SCR脱硝系统优化分析

Analysis on the Optimization of SCR Denitrification System Based on Life Cycle Cost

在严峻的环保形势、沉重的环保设施投资和运行成本以及激烈的电力市场竞争局势下,火力发电企业的SCR脱硝装置迫切需要从粗放型向精细化运行转变。为此,将全寿命周期成本引入SCR脱硝系统,从系统投资和运行维护特点出发,建立SCR脱硝系统全寿命周期成本模型,并通过对影响各成本的主要因素进行分析,研究与探讨控制和优化全寿命周期成本的途径和措施,服务电力企业SCR脱硝系统的可持续发展和合理化利用资源。

Under the circumstances of tough environmental protection,high investment and operation cost of environmental protection facilities and intense competition in the electricity market,the transition of SCR denitrification device in domestic thermal power plant from extensive operation to refined operation is urgently needed.In this article,the life cycle cost is introduced into SCR denitrification system.Then the life cycle cost model of SCR denitrification system is established based on the characteristics of system investment and operation.Through the analysis of the major factors affecting each individual cost component,the approaches and measures of controlling and optimizing the life cycle cost are explored.The results can assist electric companies in sustainable development and rational utilization of SCR denitrification system.
