The boiler adopts an environmentally friendly combustion method - full premixed combustion, and the gas and air are precisely adjusted and premixed in advance to ensure more complete combustion.
The boiler adopts a double-drum longitudinal "D" type arrangement structure; water, steam or steam-water mixture flows in the pipe; flame burns and flue gas flows outside the pipe, forming extremely fast steam-water.
Natural gas boilers operate at and a different airflow requirement for stoichiometric combustion Coal fired boilers normally operate with 3-35% O2 (about 20% excess air) Whereas natural gas boilers normally operate at 1-15% O2 (about 7% excess air)
