4 Tons of Biomass Pellet Steam Boiler Manufacturing

 SZL type chain grate boiler has high efficiency, strong overload capacity and wide adaptability of coal types. The boiler is mainly composed of upper and lower drums, convection tube bundles, water wall tubes, downcomers and headers. The upper and lower drums are arranged vertically. The combustion equipment adopts a chain-belt chain grate and is driven by a continuously variable speed device.



The boiler body of the biomass pellet steam boiler is composed of vertical upper and lower drums and convection tube bundles. Water-cooled walls are arranged around the combustion chamber, and the front and back arches are made by pouring refractory castables with the water-cooled walls as the framework, and the furnace arch has a longer service life. The left and right sides of the body are full membrane water wall structure, the boiler has good sealing performance and low heat dissipation loss, ensuring the safe and efficient operation of the boiler.

Biomass steam boiler can be used to burn fully formed biomass pellets, rice husks, wood chips, corn cobs, wood chips, etc. The boiler adopts a reasonable furnace design, the fuel is fully burned, and the black smoke can be better eliminated. High safety, long-lasting durability: The water supply adopts microcomputer control, automatic water inlet, and the life of the boiler in normal use is more than 20 years. The maintenance is convenient, and the required operation and maintenance personnel are few, which saves you investment costs while ensuring stable operation.



The 4-ton biomass boiler adopts a quick-installation design and structure. The boiler body is compact and does not take up too much space. It is more convenient for transportation and installation. The boiler double drums are arranged longitudinally to assemble the water-tube chain boiler. The fuel falls into the front end of the grate from the front coal hopper, and after combustion, it falls into the slag discharger and is discharged. The air from the blower enters the grate air chamber partition through the air ducts on both sides of the grate base, and enters the furnace through the fuel layer. The flue gas after fuel combustion passes through the furnace, the combustion chamber, the convection tube bundle I, the convection tube bundle II, and the economizer, and then exits the boiler, passes through the dust collector, and is exhausted into the atmosphere by the induced draft fan to the chimney.

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...
