Supply WNS Type Gas Steam Boiler

 The gas-fired steam boiler is composed of the main body, combustion equipment, front and rear smoke boxes, bottom frame, electric control box, outer shell and other main components. The body is a horizontal internal combustion three-pass shell structure, the front and rear flat tube plates are butt welded to the cylinder body, the furnace is a combination of corrugated furnace, straight furnace, and conical furnace, and the rotary smoke chamber is oval, smoke The tube (stretch tube) and the tube sheet are connected by fillet welding. The boiler adopts a ceramic fiber insulation layer with high insulation performance, and is packaged with thin steel or stainless steel.



This series of gas fired boilers can be equipped with various types of fully automated burners, and is equipped with a complete automatic electric control design. The boiler is equipped with a machine, valves, and electric control components. Domestic or imported parts can be selected. The boiler is a quick-installed type. Just install the boiler on the foundation, connect the water, electricity, and fuel pipelines, and then it can be put into operation.

The WNS type steam boiler adopts threaded smoke tube to enhance heat transfer, which improves the heat transfer coefficient and thermal efficiency. Because the flue gas has a disturbing effect in the tube. The use of high-efficiency heat transfer threaded smoke pipes achieves an enhanced heat transfer effect, achieves the characteristics of rapid boiler heating and pressure rise, and improves the thermal efficiency of the boiler. The arched tube sheet and the threaded smoke tube are used to form the drum, so that the drum is changed from a quasi-steel body to a quasi-elastomeric structure, and the bracing parts in the tube plate area are eliminated and stress is reduced.



The gas-fired steam boiler belongs to a horizontal three-pass water-fire tube hybrid boiler, and a bunch of threaded smoke tubes are arranged in the drum. The left and right sides of the furnace are equipped with light pipe water-cooled walls. Adopt light block grate, equipped with blower and induced draft fan for mechanical ventilation. After the fuel falls on the grate and burns fully in the furnace, the flame enters the back of the body through the flue gas channel of the middle furnace wall, and is turned from the combustion chambers on both sides to the front smoke box, and then the front smoke box is folded back into the pot The tube bundle enters the dust collector through the rear smoke box, and then is drawn by the induced draft fan through the flue to the chimney and discharged to the atmosphere.

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...
