coke oven flue gas waste heat boiler import temperature

Flue Temperature - an overview | ScienceDirect Topics

The use of a catalyst reduces the reaction temperature to 300400°C. Unfortunately this is somewhat high as a flue gas exit temperature and unless further heat is extracted will result in too low a boiler efficiency. 2 Electron-beam process. Sulphur compounds NO x and NH 4 react together in the presence of a powerful electron beam at about ...
