摘要
进气系统作为燃气电站的重要组成部分,由于普遍设计容量偏小,导致进气系统滤芯更换频繁,运行维护费用高昂。以某电厂运行数据为依据,通过全寿命周期成本(LCC)分析方法对进气系统寿命周期内的各项成本进行综合分析,构建进气系统LCC模型;通过优化进气系统容量系数k,达到进气系统净现值最低。对某F级联合循环电站计算结果表明,在设计寿命为30年,年运行小时4 500 h,燃气轮机进气系统初始投资提高576万元的情况下,每年可节约运行维护成本98.83万元,具有良好的经济效益。该模型的优化方法,对于同类地区的新建电厂进气系统选择具有重要指导价值。
As an important part of the gas-fired power plant,air intake system frequently requires to replace its filtration units,resulting in high operation and maintenance cost because of the small design capacity.Based on the power plant operational data,the life cycle cost(LCC)analysis method is used to comprehensively analyze the cost of the air intake system during the life cycle,and an LCC model of air intake system is built.By optimizing the capacity coefficient k of the intake system,the net present value of the intake system reaches the lowest value.The calculation results for an F-class combined-cycle power plant show that,with design life of 30 years,annual operating hours of 4 500 hours,and the initial investment of the air intake system increased by 5.76 million yuan,the annual operation and maintenance cost of 988 300 yuan can be saved,which has good economic benefits.Meanwhile,this model optimization method has important reference value for the design and selection of air intake system of new power plants in similar areas.
