Flue gas exit temperature
WebThe flue gas exit temperature from the HRSG is held above 100°C if it is necessary to prevent condensation, although lower temperatures are commonly used with suitable materials in order to maximize heat recovery. Figure 3.17. Heat transfer in HRSG. WebThe use of a catalyst reduces the reaction temperature to 300–400°C. Unfortunately this is somewhat high as a flue gas exit temperature and unless further heat is extracted will …

WebUsing an integrated or downstream economiser, the flue gas temperature can be reduced to 120 – 140°C, depending on the economiser design, which reduces the flue gas loss significantly. During this process, the … WebFor a "well mixed" radiant section this temperature is assumed to be equal to the bridgewall temperature, i.e. the exit temperature of the flue gases leaving the radiant section. For most applications, this is an acceptable assumption with the notable exception of high temperature heaters with tall narrow fireboxes and wall firing where the ...
