Abstract
In order to make full use of the waste heat of flue gas discharged from cement kiln front and end for power generation and to increase heat energy utilization efficiency
a model of waste heat recovery power generation system by taking the waste heat of flue gas discharged from a new dry-process cement kiln as heat source has been established.Under condition of given waste heat of the flue gas
the main parameters of a dual-pressure heat recovery boiler using waste heat of flue gas discharged from cement kiln has been optimized by using the genetic algorithm
the maximum shaft end output of steam turbine
as well as the optimal parameters of said dual-pressure system being obtained
and influence regularity of main parameters upon the shaft end output of steam turbine in said dual-pressure system being analysed.
