WNS Series Single-Drum Oil Fired Steam Boiler

 WNS series horizontal internal combustion full wet back oil-fired boiler, the flue gas process is divided into two forms of two-pass and three-pass. The torch formed after the fuel is burned by the burner is filled in the full-wave furnace and transmits radiant heat through the furnace wall. This is a return journey. The high-temperature flue gas produced by the combustion converges in the back-combustion chamber and turns into the second pass, namely the threaded smoke tube bundle area. After convection heat exchange, the flue gas temperature gradually decreases to the front smoke box, and the second-pass boiler flue gas exits the front smoke box. The boiler body enters the economizer and condenser installed on the top of the furnace, and the flue gas of the three-pass boiler turns from the front smoke box into the three-pass, that is, the light tube bundle area, and then enters the economizer through the rear smoke box, then flows into the chimney, and is discharged into the atmosphere.



The overall structure of the single-drum oil-fired steam boiler is reasonable, compact, and meets the conditions of quick assembly. This product is composed of three major parts when leaving the factory; the boiler host, the chimney and the piping system, of which the host and the chimney have been manufactured in the factory. The matching pipeline valves and instruments have been installed at random, and the host and chimney can be assembled on site. The air source, power supply, and water pipeline can be connected on site to test the operation. The installation cycle is greatly shortened and the product quality can be guaranteed.

The WNS series steam boiler has advanced design performance. The main body of the boiler is an integral structure, the burner is assembled on the front smoke box cover, and the main body is mainly arranged with the heating surface and the combustion chamber. It has a reasonable and compact structure, low steel consumption, and a biased furnace bladder. The corrugated furnace is installed, the insulation layer is made of new light-weight thermal insulation materials, the outer packaging is made of colored thin plates, and the outer packaging is a rectangular parallelepiped, which makes the performance, weight, structural size, and appearance of the boiler have obvious advancement and Beautiful sense. The boiler water supply equipment is configured on the boiler base on the right side of the boiler to make it integrated with the main engine, and no additional foundation is required. The water circulation is simple, the structure of the pressure part is reasonable, and the water quality can be guaranteed to operate safely. Supporting The auxiliary machine is complete and the comprehensive technical performance is advanced.



This series of oil-fired steam boilers are equipped with a post-purge function to improve the working conditions of the burner and prolong the service life. The unique design of the large combustion chamber increases the radiant heating area of ​​the furnace, reduces the volume of the boiler, and reduces NOx emissions. The front and rear smoke pipe boxes of the boiler adopt a multi-stage sealing method to ensure no smoke leakage. It has a large steam space and good steam quality. The horizontal structure has ample heating area, sufficient heat transfer, stable operation of the boiler under load changes, and high combustion efficiency. The furnace bladder is arranged in a low position, and the water level safety range is large. The steam evaporation area is large and the steam quality is high.

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...
