09/03/2020 · There are two aspects to consider in the low nitrogen combustion transformation of the gas-fired central flashback boiler. The first aspect is the structure of the boiler, which makes the fuel burn more fully in the boiler after several times of combustion. The second is the burner. NOx produced by different types of burners is also different.
05/11/2020 · The main reason is that low-nitrogen combustion technology adopts low-temperature, low-oxygen combustion, and the temperature in the main combustion zone drops more. It controls and delays the ignition of pulverized coal, and reduces the amount of oxygen in the ignition area, which reduces the ability of pulverized coal to burn and prolongs the combustion process.
10/11/2020 · It reduces the emission of nitrogen oxides by changing the combustion conditions of the combustion equipment, and uses a part of the lower temperature flue gas to return to the combustion zone with lower oxygen content, thereby reducing the temperature and oxygen concentration of the combustion zone, thereby inhibiting nitrogen oxides The generation. The new low-nitrogen conversion
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.
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.
