Advantages
01
Large diameter corrugated furnace.
The combustion chamber adopts integral corrugated furnace design with large combustion space to ensure complete fuel combustion. It can effectively absorb thermal expansion and offers large radiation heating surface.
02
Sufficient heating surface.
Large total heating area absorbs available heat fully, resulting in low flue gas temperature and less heat loss. Reasonable stress structure ensures high thermal efficiency.
03
Strong heat load regulation capacity.
The boiler adopts large-diameter shell with big water volume, featuring strong adaptability to load fluctuations and stable pressure.
04
Effectively eliminate low-temperature boiling inside hot water boilers.
The hot water return system is scientifically arranged. It enhances water-side turbulence on the high-temperature heating surface, prevents local low-temperature boiling, and thoroughly solves the cracking problem of high-temperature tube plates and tubes.
05
Reliable pressure and temperature protection.
The boiler is equipped with multiple control protections for boiler pressure and water temperature, as well as flue gas over-temperature protection, to ensure safe and reliable operation.
06
Advanced automatic control level.
The boiler controller is equipped with high-quality electrical components from Siemens, Delixi and other brands, with stable and reliable performance.
