Pressurized Hot Water Boiler (I7)
The IRISH I7 boiler adopts FIR flue gas internal circulation combustion technology, featuring low excess air coefficient, large turn-down ratio, small exhaust heat loss, and low gas consumption. The flame has low requirements for furnace volume, and the air-gas mixing area is separated from the combustion area, avoiding the generation of instantaneous nitrogen oxides and achieving ultra-low nitrogen emissions without external devices.
