Thermal economic analysis on low-temperature waste heat recovery
摘要
Abstract
Agalnst the characteristics of low-temperature waste heat of flue gas and turbine exhaust steam in CFB power plants,process that using the low pressure economizer combining with the type Ⅰ absorption heat pump to recover low-temperature waste heat was proposed.On the basis of THA and rated extraction conditions of a 150 MW unit,relative calculation was carried out.The results show that,after adopting this heat recovery technology,under the above two working conditions,the unit power generating load increased by 2.37 MW and 2.97 MW,the circulating thermal efficiency enhanced by 0.51% and 0.60%,separately. Furthermore,the circulating water in cooling tower reduced,so that the heat load decreased.关键词
