Gas boilers, as the name suggests, refer to boilers whose fuel is gas, gas boilers and oil-fired boilers, Electric boilers are the most economical, so most people choose gas boilers as boiler equipment for steam, heating and bathing.

The furnace chamber of the common gas boilers on the market is affected by the volume, the internal space is small, the combustion is not sufficient during combustion, and harmful gases such as nitrogen oxides are easily generated, and the connection method between the furnace chamber and the main flue is generally square due to process limitations. After the high temperature of the flue gas rises upwards, it is easy to form a high-temperature airflow vortex in the square furnace, which is not conducive to the rapid entry of the flue gas into the separate flue for heating; there is no induced draft fan at the exit of the traditional smoke collecting box, and a small amount of gas will remain at the end of the gas combustion. In the furnace and the main flue, it is easy to cause safety accidents during the next ignition and combustion.

How to design a fire exhaust gas boiler with reasonable structure, ingenious design, more complete combustion, less nitrogen oxides, safer operation and more convenient operation is a problem that needs to be solved at present.
