2 ton industrial boiler low nitrogen burner gas gas burner

01/10/2001 · Secondly, the exhaust gas generated during the combustion process of natural gas boilers is one of the main sources of NOx in the air. Therefore, on the basis of ensuring the safety of the

01/04/2021 · FGR low-nitrogen combustion technology uses the pressure head of the combustion-supporting air to suck back part of the combustion flue gas, enter the burner, and mix and burn with the air. Due to the recirculation of the flue gas, the heat capacity of the combustion flue gas is large, the combustion temperature is reduced, and the NOx is reduced.

Low-NOx Burners for Industrial Boilers | HPAC Engineering

09/01/2013 · In a standard D-style industrial boiler firing natural gas, a standard burner without FGR can achieve 85 to 100 ppm, while a burner with FGR with staged air/fuel can achieve 30 to 50 ppm.

Changzhou Qishuyan Power Generation 40-ton Gas Boiler

26/08/2020 · Low nitrogen emission targets are achieved through technical schemes such as boiler replacement, combustion equipment modification or terminal treatment. There are mainly the following several common governance schemes: 1.Boiler replacement is a technical means to replace the boiler body. The key is to control the initial emission concentration of NOx from boiler flue gas to meet the requirements of low nitrogen

Low nitrogen transformation - EBICO burner

If some boilers are installed earlier, the current nitrogen oxide emissions of boilers in the region are more stringent requirements, and the exhaust emissions after combustion of the burner cannot meet the latest standards for pollutant emissions established by the state, then it is necessary to carry out low-nitrogen combustion transformation, which is mainly the transformation of gas boiler burners at present.

1.4 Natural Gas Combustion - US EPA

Low nitrogen retrofit plan for natural gas boilers Gas boiler flue gas NOx is produced due to the high temperature of gas combustion which ensures that the center temperature of the furnace flame is lowered and the formation of NOx is suppressed under the condition that the combustion status of the furnace does not change much.
