The fire tube steam boiler adopts a horizontal wet back three-pass structure, and all flue gas channels are placed in water. The rear part is equipped with a waste water tank and a complete thermal insulation outsourcing design. The thermal efficiency of WNS type firetube boiler is above 98%, the product design is novel and the structure is reasonable. The boiler has good process performance, safety and reliability, so that this product has outstanding quality. It is the latest development of a new product. This product leaves the factory after being tested and qualified. It is an ideal heating equipment for industrial and mining enterprises, service industries and other users. We will strive to provide first-class after-sales service to ensure users’ safe and economic use.
The horizontal steam boiler control system uses an intelligent computer controller. It has automatic control functions such as automatic, combustion, and circulation control, which is easy to operate. Water temperature control has automatic control functions such as digital temperature display, temperature control, and over-temperature protection. Users can set the water temperature arbitrarily between 30°C and 90°C to ensure energy saving and high efficiency. With time control function, the switch time can be set arbitrarily according to user needs. And automatically record the failure, convenient maintenance. This series of boilers product have compact structure design, imported color panels, beautiful appearance, not easy to rust, and small installation area.
WNS series steam boilers are symmetrically arranged with heat transfer tubes, threaded tubes and smooth tubes are combined, and the super large heat transfer area enables the boiler’s thermal efficiency to reach more than 95%. The manufacturing process of WNS type firetube boiler is strict, and butt welding is used extremely harshly. Increase the boiler safety factor and prolong the service life of the boiler. The low-position combustion chamber makes the safety range of the water level larger and increases the vapor phase space of the boiler, and the steam-water separator makes the steam quality better (steam dryness reaches more than 97%). The water level control system adopts electrode type water level control, with high, medium, low and extremely low water level protection.
This series of steam boiler control has multi-layer safety interlock protection device. Such as: steam pressure protection, high temperature protection, burner flameout protection, safety valve protection, password protection, explosion-proof door protection, so that the safe operation of the boiler is always in a controlled state. WNS series horizontal boiler is manufactured by the whole machine. The optional primary instrument valve, burner and water pump are imported brands to ensure that every link of the boiler is reliable. According to the design specification, the furnace inspection door, head hole, hand hole, fire hole, explosion-proof door and smoke box door can be opened before and after, convenient maintenance and cleaning.
WNS type firetube boiler adopts high quality refractory material without preheating load. The boiler has high thermal efficiency and stable air pressure. Steam that can be produced in a short time. Low noise, low fuel consumption, low smoke emissions, small combustion safety. Thus saves the fuel cost, improves the economy, is the environmental protection and energy saving product. In the ignition process, fuel pressure, fuel temperature, atomized steam pressure, atomized steam temperature and other parameters must meet the requirements of the operation rules. The oil gun was observed on the spot and the fire test returned to normal. Forbid short contact fire detection signal to put oil gun into operation forcibly. When the flow rate of a single oil gun is greater than 0.65kg/s, the oil gun should be immediately out of operation.
