industrial natural gas diesel oil lpg fuel fired central heating hot water boiler for hotel greenhouse school hospital

WNS series gas/oil fired hot water boiler is horizontal three pass fire tube wet back full automatic steam boiler. It normally suitable for 0.35MW to 14MW 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:350kw to 14000kw(0.35MW to 14MW)
3.Pressure:atomosphere pressure or 0.7Mpa or 1.0Mpa
4.Hot water temperature:85 /95/115 degree
5.Design fuel:natural gas, lpg,lng,cng,biogas, diesel oil,heavy oil
6.Structure: three pass fire tube wet back

WNS series full automatic hot water boiler adopts horizontal three return wet back structure, and avoid the problems that the smoke box of the dryback, and central backflash system could be sealed and the temperature of the smoke box could be too high.The furnace is made of advanced structure, corrugated furnace, which increases the heat transfer area and stability of the furnace.The smoke pipe adopts the high efficient heat transfer fitting, the thread smoke tube, which improves the heat transfer coefficient of the smoke tube.

Safety: strictly in accordance with the Atmospheric pressure hot water boiler Safety Technical Supervision Regulations.Unique anti-dry burning temperature control device with one more protection.
Convenience: automatic monitoring of all operations, after-sales service on call

Main Features:
A. Simple and intuitive operation interface

With touch type as the control programming, can at any time display fan, water pump, oil pump and other operating conditions and flame stepless change state, with a full range of online help, easy to operate, suitable for any cultural levels of people.

B. The operation is fully automatic and unmanned
With automatic flame proportional regulation, automatic furnace purge and flame, wind pressure, oil return pressure automatic detection functions.In addition, the steam boiler also has continuous automatic water supply, surface discharge automatic control and water level low limit, high limit automatic detection functions.

C. Automatic system start and stop
It has the functions of automatic start and stop setting, time correction, regular start and stop, multiple priority start and stop, pre-setting of working day and rest day, automatic judgment of rest day, etc.
The boiler has the standby function when the pressure is higher and the self-starting function when the pressure is lower.It has the function of automatically stopping the furnace when the water level is too high and releasing water before starting again.

D. High reliability of the system

It has the interlocking protection function of oil pump, water pump and fan overload, ignition failure, abnormal flameout, fan no wind, gas leak detection failure, gas leak, gas pressure too low, smoke temperature and gas pressure, and oil return pressure too high fault.Have operation password, system debugging password, user program OEM protection password.In addition, the hot water boiler also has the interlocking protection function of circulating water vaporization, circulating water determination, water outlet temperature exceeding and other faults.

E. Rich extension functions

1. Multiple boilers can be networked, and the number of boilers can be automatically selected and the load of each boiler can be allocated without setting the main console.

2. The touch screen has remote monitoring function.

3. Through telephone dial-up network, our company can monitor the operation of each boiler at any time.
