Low Nitrogen WNS Series Oil-Fired Steam Boiler

 The WNS series oil-fired steam boiler adopts a fully wet back structure, and the high-temperature flue gas is surrounded by water, which solves the cooling and sealing problems of the flue gas chamber and improves the operating environment of the boiler. The addition of the condenser (made of finned tube) increases the efficiency of the boiler to more than 98% and saves operating costs. At the same time, the boiler is equipped with a leakage protection function. Once the control system detects the leakage of the electric heating element, the boiler will automatically cut off the power supply to ensure the safety of workers and the boiler and improve the service life of the boiler.



The oil-fired steam boiler has complete protection functions, with water shortage protection and pressure relief protection to ensure the safe operation of the boiler. The outer packaging is made of stainless steel, which greatly increases the corrosion resistance. The front and rear smoke box covers of the boiler are movable, which greatly reduces the difficulty of maintenance and improves the efficiency of maintenance. The design of the rear view device makes it easy for workers to observe the burning status.

The condenser of this series of boiler products adopts "low dew point corrosion" special steel, which improves the service life of the boiler. The internal smoke pipe adopts a threaded structure, which improves the heat transfer efficiency and strengthens the heat transfer effect. The heating surface of the WNS series boiler is well arranged, which ensures the water circulation and thermal circulation, greatly improves the heat transfer effect, and achieves a good condition.

The WNS series oil-fired boiler control system controls the start and stop of the circulating pump according to the boiler water temperature. When the boiler water temperature reaches the set value, the hot water circulating pump starts. When the water temperature falls below the set lower limit, the hot water circulating pump stops. A condenser is installed at the end of the boiler, and the waste heat discharged from the tail of the boiler is used to increase the inlet water temperature of the boiler and reduce the exhaust gas temperature, so that the thermal efficiency of the boiler can reach more than 99.9%, which saves operating costs.



The combustion, water level, temperature and steam pressure of WNS series boilers can be automatically adjusted and controlled automatically, which not only facilitates the operation of workers, but also improves safety. This boiler has the characteristics of compact structure, beautiful appearance, simple operation, safe and reliable operation, and has been widely used in all walks of life.

Parameters and technical requirements of 6-ton gas-fired steam boiler for hospital use

 The 6ton gas-fired steam boiler is commonly used in hospitals, and its process requirements are as follows: Natural gas boiler: natural gas → burner → boiler → steam → sub-cylinder → steam point. Tap water constant pressure water supply → water softener → soft water insulation water tank → energy saver → boiler. Hospitals are densely populated places, so the requirements for boiler equipment and suppliers are relatively strict. Suppliers of 6ton gas boilers must have a Class A boiler manufacturing license, a pressure vessel manufacturing license, a Class 2 boiler installation, renovation and maintenance license or above. The equipment supplier shall be responsible for obtaining relevant certificates and fees such as the registration certificate for installation and use of boiler equipment. The water supply of this series of gas boilers is designed with a flue gas condensation recovery device to recover the heat energy of the flue gas, and the exhaust gas temperature is less than...

SZS Gas-Fired Horizontal Water-Tube Saturated Steam Boiler

 The pipelines within the scope of the SZS watertube steam boiler only include the valves and pipelines from the flange of the return water check valve to the outlet valve and drain valve of the boiler body. Accessories include valves and gauges for the boiler body. Such as pressure gauges, air valves, spring safety valves, outlet and return valves, check valves, thermometers, etc. The SZS gas-fired steam boiler is equipped with a flue gas condenser at the tail of the boiler body, which reduces the flue gas temperature (<70°C), improves the boiler efficiency and reduces the harmful components in the flue gas. The boiler adopts micro-positive pressure combustion, and the furnace wall tube is a full-membrane wall structure. This series of boiler products has a certain pressure bearing capacity, and no smoke leakage and air leakage will occur when running under a slightly positive pressure state. The boiler is a self-contained boiler, which can shorten the installation period whi...

35 Tons SZS Gas Steam Boiler

 The SZS gas fired steam boiler is equipped with a flue gas condenser at the tail of the boiler body, which reduces the temperature of the flue gas, improves the efficiency of the boiler, and reduces the harmful components in the flue gas. The szs gas boiler adopts micro-positive pressure combustion, and the furnace wall tube is a full-membrane wall structure. The 35ton gas-fired boiler has a certain pressure-bearing capacity, and there will be no smoke leakage and air leakage when running under a slightly positive pressure state. The boiler is a self-contained boiler, which can shorten the installation period while meeting the transportation size requirements. At the same time, the aluminum casing and the skeleton are transported and connected by bolts, which are convenient for disassembly and maintenance. The furnace of this series of boiler products adopts a model water-cooled wall structure, and the whole boiler adopts an air-tight inner shield with a fully enclosed welding s...
