WNS Series Steam and Hot Water Oil (Gas) Boiler Model Description

　　Fully automatic oil and gas boilers, complying with national standards and using internationally popular fire tube three-return internal combustion design and manufacturing. The detachable front and rear smoke boxes make boiler maintenance and upkeep easier, with a more compact and reasonable structure. This series of boilers uses high-quality combustion devices, has a highly automated system, uses light oil, heavy oil, city gas or natural gas as fuel, and uses pressure atomization combustion, making operation extremely simple, safe and reliable. It is a high-efficiency product worthy of user trust.

　　Boiler Overview:

　　Functionally divided into four types: heating, bathing, combined use, and built-in heat exchanger. The heating boiler provides a heat source for the heating system. The inner wall of the bathing boiler is treated with anti-corrosion. The combined boiler is divided into two systems: heating and bathing. The bathing water is provided by the built-in copper coil, resulting in cleaner and more hygienic water. The boiler with a built-in heat exchanger has a large-capacity pure copper heat exchanger, with a heat exchange coefficient close to 100%.

　　Using imported burners, suitable for light oil, heavy oil, city gas, natural gas and other gas and liquid fuels.

　　Oil and gas hot water boilers are down-fired fire tube boilers. After the fuel gas and oil are sprayed and atomized by the burner, they burn under slight positive pressure in the furnace. The high-temperature flue gas rushes forward along the furnace to scrub the smoke tube heating surface, and after convective heat exchange, it reaches the front smoke box, then enters the rear smoke box after heat exchange through the smoke tube, and is discharged into the atmosphere through the chimney. This boiler is equipped with an imported burner, fully automatic program control, high degree of automation, which can make the boiler achieve ideal combustion effect. This boiler type is equipped with an original imported burner, computer full-scale simulation control design, the heating surface and flue gas flow have been fully optimized design, the structure is more compact, installation and maintenance are more convenient. Using advanced centrifugal glass wool multi-layer insulation, less heat loss; imported color steel plate packaging, beautiful appearance.

　　Can provide heating and domestic hot water for schools, bathhouses, hotels, hospitals and other institutions.

　　Boiler Features:

　　High efficiency: Horizontal boilers use large furnaces, high radiation surfaces, sufficient combustion air, and high utilization rate of heating surface area. The application of threaded smoke tube technology not only expands the heat transfer area, but also its self-cleaning function for smoke dust can effectively reduce thermal resistance and improve heat transfer effect: Vertical boilers are down-fired fire tube boilers. The fuel is atomized and burns under slight positive pressure in the straight furnace. Using advanced centrifugal glass wool multi-layer insulation, heat loss is reduced.

　　Energy saving: Thermal efficiency higher than 95%, intelligent fully automatic control, with automatic temperature adjustment, over-temperature alarm standby, low-temperature antifreeze at night in winter, and can automatically adjust the supply temperature according to the outdoor temperature to maximize energy saving.

　　Environmental protection: Using reasonable afterburning design, complete combustion, reducing the degree of combustion, thus reducing the amount of smoke emission, and reducing the emission of harmful gases such as NOx to a minimum, meeting strict environmental protection requirements.

　　Safety: Atmospheric pressure boilers use pressure-bearing connection structure, safe and reliable, and have a long service life. It has multiple interlocking protection functions such as over-temperature, water shortage, overload, ignition failure, gas boiler abnormal pressure shutdown, and gas leakage self-check alarm.
