Horizontal Internal Combustion Three-Pass Fire Tube Gas Fired Boiler

 The WNS series horizontal internal combustion three-pass fire tube boiler is a small and medium-sized oil and gas boiler type improved by integrating advanced experience and technology at home and abroad. It has been widely used in industries, households, hotels, hospitals and other departments and places, and has been marketed. Southeast Asia and other places. This type of furnace has stable quality and good technical performance. Many boiler manufacturers produce this type of furnace. It is a gas-fired boiler with a wide range of applications, complete varieties and high efficiency.



The flue gas process of fire tube steam boilers generally adopts a three-pass arrangement, a full butt-welded wet-back structure, a corrugated tube in the furnace, and an optimized combination of threaded and smooth tubes in the convection area. The flue gas process is long and the heat transfer effect is good. . Using advanced burners, it can be equipped with domestic burners or foreign burners. At present, many manufacturing plants are equipped with burners produced in Germany, France, Italy and other countries. The combustion technology is advanced and perfect, with fast start and stop, low fuel consumption, high thermal efficiency, soot and NO, and emissions can meet national standards.

The fire tube gas boiler is equipped with a complete automatic control device, which realizes automatic control and protection of the boiler drum water level, steam pressure, combustion, etc., to ensure the safe and stable operation of the boiler. The boiler adopts a combined quick installation structure, compact and reasonable layout, light weight, less land occupation, simple and quick installation, and convenient maintenance.



The auxiliary equipment of this series of boiler products is complete. In addition to the burner, control cabinet and chimney, the auxiliary equipment of the oil supply and water supply system can be configured as a complete set according to user requirements. According to user requirements, the boiler can use fuel oil, such as light oil, heavy oil or residual oil, as well as various types of gas, such as natural gas, artificial gas, liquefied petroleum gas, etc.; it can also use two fuels at the same time or use two fuels interchangeably . According to different requirements, different burners can be configured.

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...
