Low nitrogen three return gas hot water boiler

Ⅰ.Application

This boiler is mainly used for heating, hospitals and hotels.

Ⅱ. Applicable fuel

Natural gas, diesel, heavy oil, light oil, biogas, LPG and coal gas.,etc

Ⅲ.Advantages

1.Sufficient heat: the total heated area of the boiler is sufficient, which can fully absorb effective heat, smoke exhaust temperature is low, heat loss is small, to ensure sufficient output, high efficiency.

2.Strong heat load regulation ability: large diameter of boiler shell, large water capacity, strong adaptability to load changes, stable output.

3.Reliable pressure and temperature protection: boiler pressure, water temperature set multiple control protection, as well as smoke temperature protection, to ensure the safety of boiler operation.

4.Advanced technology: internal combustion wet back type automatic gas hot water boiler, the pressure components are all welded, composed of corrugated furnace bile combustion chamber, back combustion chamber, smoke pipe and energy saving device. After the fuel is burned in the burner and the furnace chamber, the flue gas passes through the back combustion chamber, the second return convection smoke pipe, the front smoke box, and the third return convection smoke pipe through the flue into the energy saver and finally discharged through the chimney.

    The backcombustion chamber realizes the structure of "fire in water", which fundamentally solves the overheating problem of the smoke box. An explosion-proof door is arranged at the back of the backcombustion chamber, which doubles as an inspection hole, through which the furnace can be inspected.
