Fuel gas steam boiler

WNS series automatic fuel and gas steam boiler adopts horizontal three-return wet back structure to improve boiler operating environment and improve boiler efficiency and service life; all flue gas channels are placed in water, finned tube condenser at the tail and perfect insulation Outsourcing design, the smoke box seal adopts the labyrinth structure to avoid the smoke leakage phenomenon of the smoke box; the inner and outer cylinders have the combination of the corrugated furnace and the conical furnace with good expansion performance, and the size of the furnace is combined with the flame diffusion. The flow area of ??the flue gas flow is sequentially reduced, so that the flue gas flows at a constant speed, ensuring the heat exchange time of the high temperature flue gas in the furnace, and achieving an excellent heat transfer effect; the thermal efficiency of the condenser device is as high as 90% or more; Ignition, automatic adjustment of combustion state, make combustion more fully, save fuel, low NOx emission and reduce pollution; intelligent energy-saving control system, control boiler and steam supply (water supply) system, adjust fuel supply with different loads, and save energy; The installation method is the whole quick-loading boiler, the vibration is small, there is no special requirement for the foundation, no need to fix the anchor bolts, and the installation is simple and easy. . The movable burner structure can be matched with various burners, the burner head can be replaced, and the furnace body can be repaired conveniently and conveniently. The front and rear smoke boxes adopt the movable detachable structure, which can conveniently inspect, maintain and maintain the interior of the boiler, which is simple and convenient. The product design is novel, the structure is reasonable, and the process performance is good, which makes the product have excellent quality. The whole series of products use the original low-nitrogen burner, which reduces the pollutants such as CO2 and NOx by 40%, which is the leading environmental protection in the world. Technical boiler.
