Automatic Oil Fired Hot Water Boiler 4Ton Boiler For Greenhouse Heating
Introduction of hot water boiler
WNS series gas/oil fired hot water boiler is horizontal three pass fire tube wet back full automatic steam boiler. It normally suitable for 500kg to 20ton/h capacity, use all kinds of gas and oil fuels,such as natural gas, lpg,lng,cng,city gas,biogas, diesel oil,heavy oil.
1. Model: WNS
2. Capacity: 500kg/h-20ton/h
3. Design pressure: 1.0Mpa(10bar), 1.25Mpa(13bar), 1.6Mpa(16bar),2.5Mpa(25bar)
4. Stem temperature: below 224 degree
5. Design fuel: natural gas, lpg,lng,cng,city gas,biogas, diesel oil,heavy oil
6. Structure: three pass fire tube wet back
Advantages of industrial hot water boiler
1. High effiency(exceed 92%) and energy saving(save gas 3-5m3/h;save oil 3-5kg/h)..
(1). Three pass structure,which extend the flow of smoke and enhance the heat transfer.
(2). Adopt bog size whole corrugated furnace,big heating area,sastify the free expansion of boiler, improve the boiler effiency.
(3). Whole adopt corrugated tubes,strengthening heat transfer and eliminating welding stress. Other companies also use corrugated tubes, but we adopt the latest professor “Li Zhiguang”(a very famous boiler expert in China)technoly,the depth of the screw thread and spacing between two screw threads are rationally designed.
2. Enough steam output and high quality steam.
(1). Our boiler design big size water volume,the steam output is stable and steam quality is good.
(2). Design special steam water separator,reduce steam humidity and improve steam quality.
3. Safe and reliable.
(1). Whole wet back structure and transition multi-loop full-temperature condenser design, ND just material, fin tube design,which highly reduces the back plate sheet temperature(around 50°).
(2). Double layer 12cm aluminum silicate insulation material,two stage anti-leak design and tight seal to avoid leakage phenomenon.
(3). Design tension bars,increasing the tube plate strength, preventing cracking.
(4). Explosion proof door design,prevent explosion, reduce the damage to the boiler, improve the safety of boiler.
(5). Two water level gauges and two Spring Safety Valve, Backup protection, safe and reliable.
