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.

Product Features:

1. WNS series oil fired boiler adopts the boiler structure of three passes fully wet back technology.

2. The design of furnace heat transfer and flue gas tube radiation heat transfer is reasonable, the boiler layout is reasonable, and the thermal efficiency is high.

3. The water capacity of the boiler is larger, and the whole radiation heat transfer and heat exchange technology is adopted, which is especially suitable for medium and large boilers.

4. The furnace adopts a unique combustion chamber layout, the whole combustion chamber is located in the center of the boiler water, making full use of radiation heat transfer to heat the boiler water, and the corrugated furnace is used as the combustion chamber so that the combustion is full, the heat exchange is more full, and the thermal efficiency of the boiler is higher.

5. The design of the furnace heating surface is simplified, with a larger heating area, smaller stress, more stability, and higher thermal efficiency.

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.
