Product Description

WNS Series High Efficiency Oil Fired Steam Boiler

The product model is WNS, which is a horizontal internal combustion three-return fuel (gas) fast-loading integrated boiler with wet back structure. The waveform furnace gallbladder and the reburning chamber are the first return, the second return is the flue gas pipe, and the third return is composed of an energy saver and a condenser. Boilers are equipped with complete automatic control devices and safety protection devices to realize automatic water level control, alarm and shutdown of the lowest water level; automatic ignition of boilers, automatic adjustment of burner firepower and flame-out protection to ensure the safe operation of boilers.

Boiler softening water enters the condenser first and returns to the soft water tank after preheating in the condenser (and cooling the flue gas at the same time). The preheated softening water is fed to the energy saver through the feed pump, heated further by the energy saver, and then fed to the boiler body.



Brief Introduction of Boiler Operating Conditions
The boiler can operate steadily under 80%-100% working conditions. Under 100% rated load, the operating parameters of the boiler are: feed water temperature is 20 C, rated working pressure is 1.25 MPa, 10 tons of water vapor with temperature of 193.4 C can be produced within an hour. If the fuel is natural gas, the calculated thermal efficiency is 98.96%, the exhaust gas temperature is 48.93 C, and the fuel consumption is 754.78NM3/h (the product is used for a day). Low calorific value of natural gas (> 36.36MJ/NM3).

Technical Parameters

Note: the fuel consumption in the table is based on light oil low calorific value 42915KJ/Kg (10260Kcal/Kg), natural gas low calorific value 35588KJ/NM3 (8500Kcal/NM3) and liquefied gas low calorific value 45998KJ/Kg (11000Kcal/Kg). Calculation of low calorific value (16750KJ/NM3 (4000Kcal/NM3) of urban gas.
