本文采用“费用法”即“综合成本效益法”评价加热炉余热回收设施的经济性,由此导出经济末端温差和经济热效率的计算方法,并对有关设计参数的影响进行讨论。
In this paper, we use the “cost method” or “comprehensive cost-benefit method” to evaluate the economic efficiency of furnace waste heat recovery facilities. The calculation method of economic terminal temperature difference and economic thermal efficiency is derived and the influence of relevant design parameters is discussed.
