Under the national strategy of carbon peaking, natural gas boilers are now widely used and have become a key focus for energy-saving and environmentally friendly upgrades in the thermal industry. Apart from the outer casing of the boiler burner, do you know how the burners of the gas boilers you use actually burn? Let's talk with senior technical experts at Kezi to discuss the combustion methods of boiler burners.

 1. Diffusion combustion, boiler burner

  The diffusion combustion method does not involve premixing; instead, the fuel gases diffuse with each other at the nozzle before being ignited. Advantages: This combustion method does not involve premixing; instead, the fuel gases diffuse with each other at the nozzle before being ignited. The combustion process is relatively simple, and the flame is relatively stable. Disadvantages: Because the flame is long, incomplete combustion is likely to occur, producing a significant amount of carbon monoxide and nitrogen oxides. This is not conducive to the full utilization of boiler fuel, improving boiler thermal efficiency, and it is difficult to meet boiler emission standards.

 2. Fully premixed combustion, boiler burner

  The fully premixed combustion method involves pre-mixing natural gas with air before combustion, with the mixed gas then entering the burner chamber of a gas boiler for combustion. Advantages: Pre-mixing air and gas, using multi-radiating surfaces for heat transfer, enhances the intensity of heat transfer. The benefits of using this combustion method are that the flame is relatively clear and the thermal efficiency is higher. Disadvantages: The premixed combustion ratio requires precision, combustion speed is fast, and the combustion must be uniform with sufficient radiative heat transfer.

   3. Flameless combustion, boiler burner

 A combustion method that evenly mixes the pre-combustion space with the gas in a gas boiler. When using this method, the oxygen required for the gas during combustion does not need to be obtained from the surrounding air; it only needs to reach the combustion zone in a mixture with the air to achieve instantaneous complete combustion.

 When choosing a combustion method, it is necessary to compare the advantages and disadvantages of different combustion methods and select the more suitable boiler burner combustion method based on project conditions and customer requirements.
