SZS Series Integrated Water Tube Boiler

 SZS integrated water tube boiler adopts double drum (or triple drum) D-type membrane fireplace chamber structure. Factory assembled or semi-bulk. High degree of assembly and quick on-site installation.

SZS series boiler adopts double drum (or triple drum) D-type membrane type hearth structure. The boiler consists of upper (middle), lower drum, membrane water wall, convection heat exchange tube bundle, superheater, tail economizer, condenser, etc. The combustion chamber adopts a full-membrane water-cooled wall structure, which has good sealing, no air leakage, and less heat dissipation. It increases the heating surface of the boiler and improves the thermal efficiency. Full-membrane wall structure, the furnace and flue have good rigidity, strong anti-explosion ability and safe operation.



This series of boiler products have a single stroke of the convection tube bundle, reducing the side resistance of the flue gas, the best economical flow rate design, slightly positive pressure combustion, and improving the heat transfer efficiency. With larger furnace volume, cross-sectional width and length dimensions, it is suitable for various burner layouts. It is convenient to arrange multiple burners. The fuel stays in the furnace for a long time, burns more fully, and is more efficient.

The large furnace size of SZS series boilers meets the requirements of ultra-low nitrogen combustion. Combined with the burner, the NOx emission can meet the environmental protection requirements of the place of use. There are many layouts of furnace water walls and convection heat exchange surfaces, the boiler heats up quickly, the boiler water capacity is large, and the operation is safe and stable.

The water tube boiler adopts high-quality thermal insulation materials and special construction technology, which has low heat loss and saves fuel.

It adopts a fully automatic burner, with ignition program control and automatic control system for overpressure, flameout, and gas leakage protection. The boiler adopts advanced mechanical and electrical integration automatic control technology. Remote human-computer interaction and data sharing can be realized through the mobile Internet.



This type of boiler realizes the matching of "boiler" and "furnace", and comprehensively considers the flue gas flow rate, steam/water cycle characteristics, flue gas flow state, flue gas flushing heating surface form, equipment flue gas pressure loss and other parameters in the design process For the impact on heat transfer efficiency and safety, optimize the structural design and material selection of the heating surface for radiation, convection and tail heat recovery.

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...
