WNS gas/oil fired central combustion boiler
This furnace used to burn the center of a unique technology, the entire wet back structure, the furnace volumn is big. Make full use of radiation furnace heat exchanger, and through the combustion of fuels burnout level, making boiler thermal efficiency improved greatly.
This simplifies the furnace heating surface design, especially for the low-power boiler.
Design structure:
1. Designed with horizontal, three passes, all-wet back structure.
2. Fire tubes are surrounded by water, and these design making efficient up to 85%.
3. Threaded tube: Strengthen the heat transfer, increase the boiler heat efficiency
4. Big combustion room design: Increase furnace heating area, decrease boiler size, and reduce the emission of the Nox Corrugated hearth make the boiler safer.
Advantage:
1. Safety: With water level, leakage steam, steam pressure control. Make sure boiler working safety.
2. Product quality ensured by: Hydraulic test, X-ray, non-destructive test.
3. Efficient: Well insulation and excellent structure.
How to use?
1. Built a boiler house.
2. Preparing piping as boiler technical data.
3. Preparing electricity as required.
4. Installed boiler as manual.
5. Commissioning boiler as manual.
6. Operating boiler.
Application:
Building heat, chemical processing, health care, laundry industrial, paper processing, textiles.
