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.

(PDF) Effects of Flue Gas Internal Recirculation on NOx ...

In conclusion flue gas internal recirculation is an effective way for NOx emissions reduction especially when combined with air-staging combustion mode.Meanwhile the characteristics of SOx emission with various flue gas internal recirculation ratios were also studied. In this work SOx emission refers to the emissions of SO 2 and SO 3 .

Feb 18 2021 · A new low NO x burner for gas boiler is designed. A hollow tube is embedded in the burner axial center line which is combined with the flared flame stabilizer to draw back the internal flue gas from inside the boiler and a flue gas recirculation tube is installed outside the boiler to draw back the flue gas from the end of the boiler.

Boiler Manufacturer Nearby - We Are in United Kingdom. 19/06/2019 · Flue Gas Recirculation (FGR) is the process of taking a portion of the flue gas from a combustion process and recirculating it back through a boiler or burner. When the process is used in internal combustion engines it is commonly referred to as exhaust gas recirculation (EGR).

Volumetric combustion has been developed to realize a high substitution ratio of biomass in co-firing boilers which features an intensive flue gas internal recirculation inside furnace. However the characteristics of NOx and SOx emis-sions in large-scale boilers with volumetric combustion were not fully clear. In this paper an Aspen Plus model of volumetric combustion system was built up ...
