WNS series horizontal fuel gas steam boiler

WNS series full active fuel (gas) steam boilers (utility model patents), adopting a horizontal three-return wet back structure, thereby improving the boiler operating environment and improving boiler combustion compliance and service life.

All the flue gas channels of the boiler are placed in the water, and the tail is equipped with a waste water tank and a perfect thermal insulation outsourcing design. The sealing of the cigarette box adopts a labyrinth structure, which avoids the occurrence of smoke leakage signs in the cigarette box.

The boiler heat obeys more than 90%, and adopts the combination of corrugated furnace and conical furnace with superior expansion performance. The size of the furnace bladder is consistent with the flame, and the area of the flue gas flow is reduced in turn, so that the flue gas flows at the same speed, and the heat exchange time of the high-temperature flue gas in the furnace is achieved to achieve a good heat transfer result.

High-performance burner with fully active adjustment that effectively matches the boiler. This burner burns fully and saves fuel, thereby effectively reducing the pollution caused by the combustion of the boiler to the environment.

The use of ultra-fine glass wool with high thermal insulation performance reduces heat loss.

Adopting intelligent energy-saving control system, boiler and steam supply (water supply) system can combine different loads to adjust fuel supply to achieve more energy-saving purposes.

The installation of the boiler adopts the group quick installation method, which has no special requirements on the foundation, does not require anchor bolts, and is easy to install.

Adopting the moving burner structure, it can not only match various burners, but also replace the burner and repair the furnace body more conveniently and quickly.

The front and rear smoke boxes adopt a removable structure, which can easily inspect, maintain and maintain the interior of the boiler.

This type of boiler is a newly developed new active fuel (gas) steam boiler with fresh product design, reasonable structure and superior process performance.
