摘要
为充分利用CHG620V8气体机的排气余热,对其余热锅炉进行设计计算和校核计算,分析了该余热锅炉的经济性,结果表明:该锅炉各受热面计算的相对误差结果均小于2%,烟气总阻力小于最大允许值,因此符合设计要求。余热锅炉产生的2.5MPa、350℃、3.677t/h的新蒸汽如果全部用于发电且锅炉年运行4000h,年发电量为61.247万k Wh;以0.37元/k Wh的市场价计算,则全年发电所获收益可达22.662万元,该余热锅炉回收利用装置运行约43个月即可收回初期投资成本。
In order to make full use of the waste heat of CHG620V8 gas engine,design calculation and checking calculation of the waste heat boiler were carried out.Furthermore,the economic performance of the waste heat boiler was analyzed.The results showed that:the relative error of each heating surface of the boiler was less than 2%,the total resistance of the flue gas being less than the maximum allowable pressure,therefore meets the requirement of design.2.5MPa,350℃and 3.677t/h new steam generated by the boiler,if used exclusively for power generation,operated in accordance with 4000 hours per year,an annual generation capacity was 612474.2kW(h.Calculated at a market price of 0.37 $per kilowatt-hour,the annual generating proceeds can be of up to 226,620 $ and it was considered that the initial investment costs of the use of waste heat boiler plant operation will be recovered in about 43 months.
