Gas steam boiler adopts D type layout, natural circulation of working medium. SZS series steam boilers is double tube tube boiler, tube longitudinal arrangement, membrane type water wall structure, micro positive pressure combustion. The boiler furnace is mainly composed of membrane wall, the flue gas from the furnace outlet into the upper and lower cylinder connected with the convection tube bundle. After the flue gas flows through the convection tube, it enters the tail heating surface.
SZS series gas fired boilers have no air leakage, small heat loss and high thermal efficiency. Compact structure, small installation volume, saving investment. This series steam boiler uses natural circulation and uses the larger section ratio, the hot water boiler uses the forced circulation, the water circulation is safe and reliable. At the same time, the boiler is equipped with efficient brand burners, auxiliary machines and accessories to achieve automatic operation. Feed water pump adopts continuous electric regulation, and has high and low water level alarm chain protection function. The furnace is equipped with an inspection hole, which provides great convenience for use and maintenance. The top of the furnace is equipped with an explosion-proof door.
SZS series steam boilers is arranged on the left side of the convection tube bundle, superheater arranged in the furnace exit turning area. In order to improve the boiler thermal efficiency and improve the combustion condition, the tail are arranged respectively energy saver, maximum energy saving. This series of SZS gas-fired boiler superheater adopts countercurrent arrangement, and adopts surface desuperheater to meet the requirements of steam temperature regulation, in order to prevent the superheater tube wall overtemperature. The surface desuperheater is arranged in the superheated steam inlet to ensure the safety and reliability of the superheater operation.
The burner of this series of boiler is arranged on the front wall, and the convection tube bundle is arranged side by side with the furnace. The flue gas generated by combustion flows through the superheater (if any), the convection tube bundle and the heating surface at the tail from the back of the furnace, and then is discharged into the atmosphere through the chimney. Equipped with imported automatic burner and advanced PLC computer control system, it can automatically and continuously feed water, program ignition, proportional control temperature control combustion, flameout protection, various alarms, chain protection, graphical operation interface, large screen keyboard operation and other automation technologies. The boiler manufacturing absorbs the combination of advanced technology, process and many years of actual boiler operation experience, through self-design and manufacturing, the price is more advantageous.
SZS series steam boilers in the design process of comprehensive consideration of flue gas flow, steam/water cycle characteristics, flue gas flow state, flue gas flushing heating surface form, equipment flue gas pressure loss and other parameters. In order to influence heat transfer efficiency and safety, the surface structure design and material selection of radiation, convection and tail heat recovery heat recovery were optimized. The use of high thermal resistance light insulation material, insulation effect is better than the traditional refractory concrete/refractory brick insulation, and the total weight of the furnace body is greatly reduced. A unique thermal radiation insulation measure (radiating film) is provided in the insulation layer to reduce the radiation heat loss that is ignored in the traditional insulation process.
