Low nitrogen gas boiler renovation policy

Ultra-low nitrogen boiler Beijing operation site
The modified gas boiler has a nitrogen oxide content of less than 30 mg/m3.
This type of gas boiler belongs to ultra-low nitrogen emission, detailed transformation plan:
Low nitrogen gas boiler renovation policy
1, replace the burner
Replace ordinary burners with ultra-low nitrogen burners to optimize the combustion environment of the fuel to reduce nitrogen oxides
2. Performing flue gas recycling transformation
Opening in the flue of the existing gas boiler, re-connecting a flue, and passing the flue gas into the burner for combustion
Note: The opening position of the tail of the gas boiler needs to be analyzed and measured by professional instruments to select the best opening position.
The modified gas boiler has a nitrogen oxide content of less than 80 mg/m3.
This type of low-nitrogen gas boiler can be retrofitted with only a low-nitrogen burner.
The furnace size and boiler length of the above two emission standards for low-nitrogen gas boilers must meet the requirements of low nitrogen. If the size does not meet the requirements, the modification of low-nitrogen gas boilers is not recommended. The main reasons are as follows:
1. The effect of the modified boiler cannot be guaranteed
2, thermal efficiency can not be guaranteed
