DZL Type Coal Fired Steam Boiler Manufacturing

 DZL series steam boiler is composed of main body, chain grate, front arch, back arch, light furnace wall, steel frame and insulation layer. The main body is composed of a pot shell, a smoke box, a water wall tube, a downcomer, and lower headers on both sides. The tube plate adopts a fully welded structure. The chain grate adopts light chain ten grate, thickened grate pieces, and independent air supply in sections.



This boiler has the following characteristics:

　　● Reasonable air distribution, flexible adjustment, can be adjusted at will according to combustion conditions.

　　● Thicker grate slices, higher strength, long life of the grate slices, and long overhaul period.

　　● The furnace structure designed with a unique coal combustion theory enables the boiler to have a faster combustion speed and an efficient and clean combustion effect, and truly achieve no black smoke emission.

　　● Coal types are widely adaptable, and can be burned with ⅠⅡⅢ bituminous coal and lean coal.

　　● Fully welded tube sheet, no slack leakage.

　　● Large diameter water wall, good water circulation, low water quality requirements.

　　● Lightweight furnace wall, light weight, beautiful and generous.

         ● Lengthened structure, sufficient output.

　　● Sufficient fuel, good smoke reduction and dust reduction, high thermal efficiency.




Coal fired steam boiler type DZL series is horizontal single drum boiler water tube of chain grate boiler. Boiler body for single drum longitudinal arrangement, drum and the water wall tube on both sides of the chamber radiation heating surface, on both sides of the pipe bundle pipes convection heating surface of boiler drum internal thread of smoke tube fire pipes convection heating surface, the tube plate with low stress no braced arch tube plate. Boiler is composed of upper body and lower grate, portfolio site (below DZL4 combination). Province coal machine layout in at the back of the boiler.

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...
