Design of a Waste Heat Heating Device at the Tail of a SCC6-5000F HRSG
This paper introduces a design,adding a waste heat heating device to the heat recovery steam generator(HRSG)system,installing a pipeline in the condensate return pipe,using a heat exchange device to heat the natural gas,and then returning the low-temperature water to the boiler preheater for circulation heating,thereby reducing the heat loss of the waste heat boiler,improving thermal efficiency and saving energy.Compared with the traditional water bath furnace heating unit configuration,this design does not need to configure a water bath furnace in the pressure regulating station,thereby reducing the natural gas consumption of the water bath furnace during combustion,and avoiding fires caused by deflagration,failure or other unsafe conditions of the water bath furnace or explosion accidents,which improves the economy and reduces the risk of operation of the pressure regulating station.
