Description

WNS is a traditional three-pass, wet-back horizontal firetube boiler. The first pass flows through the furnace from front to back. The furnace is corrugated to maximize efficiency while also minimizing thermal stress. Flue gasses then travel from the combustion furnace to the front chamber forming the second pass. For the third pass gases flow through tubes to the back of the boiler stack and out the exhaust vent, located conveniently in the back of the boiler. The second and third passes travel through heavy-duty seamless tubes.

Main Features
The advanced steam boiler automatic controller can ensure the simple control, safe protection for entire boiler system.
Under the commanding of PLC, the original Italy BURNER works smoothly and safely. The front/back smokebox is openable for inspection and maintenance.
Internal micro positive pressure combustion, full wetback design, spirally corrugated tubes etc can fully enhance the thermal efficiency and reduce the smoke temperature.
New type thermal insulation material and the quality stainless plate packages realize the good insulation effect and nice looking.
Compact structure makes the installation is easy, and also can reduce the cost for Boiler room construction.
industrial oil gas fired steam boiler is widely used in different fileds,including
chemical industry, food industry, building material industry, paper mills, packaging plants, garment and textile mills, printing and dyeing plants, hospitals, schools, hotels, government agencies, greenhouses, canneries, wineries, coating plants, swimming pools, washing plants, etc.
