What is the way to decrease the temperature of a flue gas

In the 1000 MW e tower-type boiler under investigation, the gas temperature deviation between the left side and the right side on the entrance cross-section of the final superheater reaches 120 K. A new method, i.e., adding an arch nose under the furnace exit, is proposed to mitigate the deviation, in which the height of the arch nose is a

Beijing's burning issue – reducing boiler NOx emissions

Low temperature hot water (LTHW) boilers produce hot water at around 90ºC and are the type most commonly found in houses and commercial premises. The hot water produced is distributed via pipework to 'wet' heating systems and hot water storage tanks. Most LTHW boilers are designed to use natural gas, but there are also designs that use mineral

Causes and mitigation of gas temperature deviation in

Flue Gas Analysis is performed by inserting a probe into the flue of the furnace, boiler, etc., between the last heat exchanger and draft diverter or any source of make-up air that could enter the flue that did not pass through the combustion process. This is known as 'in-situ' testing.
