Recirculation technology of low nitrogen burner

The flue gas recirculation technology principle of the 30mg Gas low nitrogen burner is:
10%-25% of the boiler exhaust smoke is returned from the boiler exhaust main pipe to the front end of the boiler through the FGR smoke pipe, and the flue gas volume is adjusted through the regulating damper on the FGR smoke pipe; the auxiliary gas enters the variable frequency fan after passing through the fresh air filter. After being boosted by the fan, it goes to the front end of the boiler; the fuel gas passes through the double stop valve group and the servo valve adjustment and then goes to the front end of the boiler; the boiler exhaust smoke and combustion air are mixed after passing through the mixer, and are sprayed out with the fuel gas through a specially designed nozzle. A stable flame is formed in the boiler.www.burners-china.com
