The biogas boiler body adopts wet-back three-pass, full-corrugated furnace and threaded smoke tube structure, which has good thermal flexibility. The tube plate and the cylinder adopt a plate edge connection structure. The main welding seam of the main body is a butt joint structure, all of which are welded by submerged arc automatic welding. The industrial biogas steam boiler adopts the internationally popular full wet back structure, and the large-volume design of the combustion chamber makes the combustion more complete. The fuel burns with slight positive pressure in the furnace bladder. The high-temperature flue gas enters the flue duct bundle through the back-combustion chamber and turns 180° along the furnace bladder. The compressed front smoke box then turns 180° and enters the second tube bundle. After convection heat exchange, it is discharged into the atmosphere.
The steam boiler adopts a combined control method of mechatronics control equipment and programmable logic controller (PLC). The programmable logic controller (PLC) is the “processor” of the control system. The control system is operated through the touch screen, which greatly improves the degree of automatic control and operation reliability of the boiler, and the operation is more simple and intuitive.
This series of boiler products adopt scientific product design, and the continuous operating life is up to more than 10 years. The radiant heating surface of the boiler is a full corrugated furnace, and the convection heating surface adopts threaded smoke pipes, and the heating surface is large. The industrial biogas steam boiler has sufficient heat output and the thermal efficiency can be as high as above, which is higher than the national regulations. The boiler adopts full flanged side butt welding seam, which has high reliability and low maintenance cost.
The combustion chamber of this type of gas fired boiler is reasonably designed and adapts to various fuels such as city gas, natural gas, light diesel, heavy oil, etc. The fuel is burned in the furnace with slight positive pressure and fully burned, with less smoke pollutants, and the blackness of the smoke and smoke of the boiler. Technical indicators such as blackness, density, and noise are superior to the national first-class regional standards.
The combustion chamber adopts a full-corrugated furnace structure, which not only strengthens the disturbance of the flue gas, but also increases the radiation heat transfer area. This not only increases the rigidity of the furnace bladder, but also effectively weakens the expansion stress of the furnace bladder. It not only enhances the heat transfer effect, but also promotes the combustion of fuel in the furnace. Industrial biogas steam boiler use threaded smoke tubes with high heat transfer coefficients. Strengthen the convection heat transfer effect, reduce the exhaust gas temperature, and improve the thermal efficiency of the boiler.
