Gas(oil) Fired Split Steam Boiler

Gas(oil) Fired Split Steam Boiler

This series of boilers is designed with a classic shell type, full-wet back, down-flow and three-pass design structure. The fuel is fully burned in the large-capacity combustion chamber, and the combustion heat load is low, which can greatly reduce the emission of harmful substances such as CO and NOx.

Capacity: 1-20t/h

Rated Thermal Efficiency: 97-100%

Fixed Work Stress: ≤3.82MPa

Applicable Fuel: diesel, heavy oil, natural gas, city gas, etc.

Product advantages

High thermal efficiency

The flue gas is condensed and recovered,the combustion efficiency is >98%, and the thermal efficiency is ≥104%, which can reduce fuel consumption by more than 4%.

PLC intelligent control

The self-developed PLC fully automatic intelligent control system greatly improves the reliability of boiler operation.

More corrosion resistant

The oxygen content of the feed water is less than 16%, and the boiler body material is made of silicon aluminum alloy, which is more resistant to corrosion.

Multiple protection system

Various protection systems such as water level, pressure, temperature, power supply, scale detection, etc., guarantee the safety of boiler operation in all aspects.

Long lasting

The combustion chamber is completely immersed in water, the cooling conditions are excellent, the boiler operating environment is greatly improved, and the service life of the boiler is increased.

Good sealing effect

The smoke box door and panel adopt a double-layer sealed structure, and the intelligent welding equipment can be welded at one time to prevent air leakage and smoke leakage.
