Product introduction:

WNS type gas hot water boiler adopts horizontal standard three-pass structure, the combustion mode adopts micro-positive pressure combustion, and adopts wet-back structure. The corrugated furnace is the first return pass, the threaded smoke pipe constitutes the second return pass and the plain smoke pipe constitutes the third return pass. The boiler is equipped with a complete automatic control device and safety protection device: overtemperature alarm device and interlock protection device, boiler automatic ignition, burner fire automatic regulation and flame out protection to ensure the safe operation of the boiler.

Product advantage:

1, boiler products
Horizontal internal combustion three return full wet back design, 100% corrugated furnace, with good thermal scalability, water cooled recombustion chamber, recombustion chamber and the rear tubesheet edge butt, the lowest stress, more reliable quality.
2, large diameter corrugated furnace gall
The combustion chamber of the boiler is composed of a large diameter full corrugated furnace with large combustion space, complete fuel combustion, effective heat absorption and thermal expansion, and large radiation heating surface.
3. Sufficient heat
Boiler heating area is more than 25 square meters/ton design configuration, fully absorb effective heat, low smoke exhaust temperature, small heat loss, to ensure sufficient output, high efficiency.
4, multi-functional safety explosion-proof device
An explosion-proof device connected with the furnace is provided on the back plate of the boiler to prevent the fuel from violent deexplosion in the furnace, release the high energy of the moment, and can automatically reset. At the same time, it has the function of fire viewing mirror and inspection channel, and makes use of the adjustment of combustion flame in operation, furnace inspection and easy maintenance.
5, the safe precipitation time is enough
The position arrangement of the combustion chamber of the boiler, the determination of the water level conforms to the national regulations, and the water level fluctuation time requirements of the international general norms and standards are strictly followed, with sufficient safe precipitation space to ensure the safe operation of the boiler.
6, boiler maintenance is convenient
The top of the boiler is provided with a manhole, and the front and back of the boiler are provided with a hand hole device, which is convenient for the inspection and cleaning of the equipment in the furnace and the bottom of the boiler.
