Product Description
WNS Series High Efficiency Oil Fired Steam Boiler
The product model is the WNS, which is a horizontal internal combustion three-cylinder (gas) combustible boiler with a wet back structure. The corrugated furnace and the combustion barn are the first return, the second return is the flue gas pipe, and the third return consists of the economist and condenser. The boiler is equipped with complete automatic control device and safety protection device to detect automatic control of water level, alarm and shutdown of lowest water level; automatic boiler prevention, automatic fire burner adjustment and flameout protection to ensure safe operation of the boiler.
The boiler softens the water first into the condenser and is pumped to the condenser and returns to the soft water tank (while cooling the flue gas). The preheated demineralized water is sent to the economist by the feed pump, further heated by the economist, and then sent to the boiler body.
Brief Introduction of Boiler Operating Conditions
The boiler can work from 80 to 100% working conditions style. Below the 100 rated bar, the boiler operating parameters are: feed water temperature is 20 ° C, the rated working pressure is 1.25 MPa, and 10 tonnes of water can be produced in an hour, the temperature is 193.4 ° C. If there is natural gas, then the calculated thermal efficiency is 98.96, gasoline temperature is 48.93 ° C, and fuel consumption is 754.78 Nm 3 / h (output is used for one day). Natural gas has a low calorie value (> 36.36 MJ / NM3).
