Our Products for the boiler flue gas temperature is too low

Flue Temperature - an overview | ScienceDirect Topics

The 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 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 100°C. Experiments are in hand to check if such a system, in …

5 Factors Killing Your Industrial Boiler Efficiency & What

Dec 17, 2019 · If the turbine load is too low or the high-pressure heater is disassembled, the feedwater temperature of the boiler will be reduced. Generally speaking, when the feedwater temperature rises, if the fuel quantity remains unchanged, the heat transfer temperature difference of the economizer decreases, the heat absorption of the economizer decreases, result in the flue gas temperature rises.

Jul 05, 2018 · A too low arch nose cannot eliminate the skewness of flue gas towards the rear wall while a too high arch nose skews the flue gas towards the front wall. As an important topic that may endanger boiler operation, the gas temperature deviation in large-scale tangentially coal-fired boilers has been carefully studied. improves little. The

Aug 21, 2009 · In order to avoid or reduce the cold end corrosion the gas temperature leaving the heat transfer surface in boiler is kept around 150 degrees centigrade, ranging from 120 to 155. It is very important that the metal temperature of the tubes is always kept above the condensation temperature.
