Nov 05, 2019 · Definition: A boiler flue is a component which enables gas to escape safely from boiler.In most cases, this is a pipe or a duct, which is fitted to the boiler to carry exhaust gases away from your home safely. The aim is to remove waste products without exposing you or anyone around you to them.
According to China's latest boiler environmental protection standard GB13271-2014 "Boiler Air Pollutant Emission Standards": from July 1, 2014, the emission value of pollutants in newly built oil-fired boilers is 30 mg/m3 for particulate matter, 200 mg/m3 for sulfur dioxide, and nitrogen oxidation The particulate matter is 250 mg/m3; the pollutant emission value of the newly built gas boiler is 20 mg/m3 …

Flue gas recirculation, or FGR, is the most effective method of reducing NOx emission from industrial boilers with inputs below 100 MMBtu/hr. FGR entails recirculating a portion of relatively cool exhaust gases back into the combustion process in order to lower the flame temperature and reduce NOx …
We started manufacturing process heating equipment for large commercial and industrial applications in 1963. We have a wide range of standard product boilers but distinguish ourselves by providing custom solutions with ease and minimal additional cost.
