1.4MW industrial natural gas diesel oil lpg fuel fired hot water boiler for greenhouse,factory
General features of WNS series hot water boiler:
1. horizontal , gas & oil fired , water tube, industrial and low pressure;
2. wetback and three-backhaulstructure design;
3. With high efficiency economizer, the thermal efficiency can reach more than 90%.
4. The spring-loaded type explosion door ensures the boiler safety
5. The removable smoke boxfacilitates the maintenance
6. Internal micro positive pressure combustionreduces the low temperature corrosion.
7. Equipped with protection devicesfor overheating, overpressure, lacking water, leak detection, flameout, etc. This ensures the boiler to operate safely and efficiently.
WNS series atmospheric horizontal fuel(gas) hot water boiler is a kind of horizontal internal combustion wet–back shell boiler,it is constructed by shell,internal furnace,smoke-circling box,flue tube and etc,it adopts the import burner and such fuel as light oil,heavy oil,city gas,liquid fuel and etc.

Boiler Advantage
The heat transfer tube adopts threaded tubes, which are evenly and symmetrically distributed on the left and right sides, extending the flue gas flow, effectively increasing the convective heating surface of the boiler, making the high-temperature flue gas in a turbulent state, and playing a self-cleaning effect to achieve enhanced transmission. The effect of heat.
The steam boiler has a large vapor phase space and a built-in high-efficiency steam-water separator to reduce the steam humidity to below 3%; the application of advanced digital intelligent control technology can accurately monitor the entire combustion process remotely, and reliable imported electrical components make the equipment safe in operation Guaranteed.
According to user requirements, a remote communication interface can be added, which can control the operation of multiple boilers in parallel, print boiler operating parameters in real time, and the computer memory system can record boiler failures and monitor boiler operation.
The boiler is equipped with complete safety accessories: water level control, pressure control, alarm device, gas leakage prevention, flameout protection, over-temperature and over-pressure protection, explosion-proof door protection, etc., multiple safety interlock protection, so that the equipment has no safety hazards.
