Gas Fired Steam Boiler For Sale

 Gas-fired steam boiler refers to a steam boiler heated by gas combustion. The horizontal steam boiler is a shell-type full-wet back flow three-pass pyrotechnic tube structure. The flame burns in a large combustion chamber with slight positive pressure. The combustion heat load is low and the exhaust is reduced. The smoke temperature, energy saving and consumption reduction, adopts the structure of corrugated furnace bladder and threaded smoke tube, which not only improves the heat absorption strength of the boiler, but also satisfies the need of thermal expansion of the heat exchange surface.



The exhaust gas temperature of a gas-fired steam boiler is one of the basic parameters of the boiler. Choosing a lower exhaust gas temperature can reduce the exhaust gas loss of the boiler and help improve the thermal efficiency of the boiler. If the exhaust gas temperature of the boiler drops to a sufficiently low level, the superheated water vapor in the flue gas will condense and release the latent heat of vaporization.

The condensing steam boiler is the use of flue gas condensation waste heat recovery device to absorb the sensible heat in the exhaust smoke of the boiler and the latent heat released by the condensation of water vapor to achieve the purpose of improving the thermal efficiency of the boiler. The boiler adopts a flue gas process with a three-pass form, a symmetrical wet back structure, a corrugated furnace with a large auxiliary injection heating area, and eliminates the thermal stress of the furnace, the flame box is a symmetrical and eccentric structure, and the convection section smoke pipe adopts a threaded tube or a light The tube has a spoiler inserted to optimize heat transfer.

The burners used in this series of steam boilers have flame monitoring, automatic purge, and flameout protection functions. The harmful components in the flue gas are lower than the standard (400mg/m3 lower in NOx emissions). Optional touch screen + PLC controller, digital inspection and control system, with timing control, work record, leak detection alarm, pressure protection, temperature control, water shortage protection and other functions, and can add factory timing locks, and can reserve a computer communication interface Realize integrated control.



The exhaust port of the gas fired boiler can be equipped with a condensing heat exchanger, and the water vapor in the condensed flue gas absorbs the latent heat of condensation, thereby improving the thermal efficiency of the boiler. Reasonably design the burner interface and the high temperature and heat conduction parts of the front and rear smoke boxes to ensure that the surface temperature of the furnace body meets the design specifications. The boiler is delivered as a whole, integrating pressure accessories, and easy to install.

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...
