WNS series horizontal internal combustion boiler is a boiler shell type 3 passes wetback oil/gas fired boiler. After fuel is being atomized by burner, flame is full of the wave furnace and transfer heat via furnace wall, this is 1st pass; the high temperature smoke is collected in reversal chamber and then enters 2nd pass which is grooved tubes bundle area; after heat convection, air temperature gradually falls and goes to front smoke box and turn to 3rd pass, which is smooth tubes bundle area, and then enters chimney passing back smoke box and exhausted to the atmosphere.
1. Digitized manufacture
The key part such as material cutting, rolling, drilling are proceeded by advanced CNC machining process to reduce the assemble stress and extend boiler working lifetime.
The front and back smoke chamber plates are cut by CNC plasma cutting machine and looks tidy and beautiful.
2.Easy operation and maintenance
Fully automatically operating, with automatically adjustment and protection of burning, water level, temperature and steam pressure.
3. Longer working life
Smoke tube and tube sheet connection is expanded first to eliminate the gap between them, then adopt automatic argon arc welding to relief the stress and expand boilers working life.
Longitudinal and girth joint adopt advanced automatic submerged-arc welding for good welding quality. All longitudinal and girth joint will have 100% radiographic inspection.
Fin tube us ND steel or stainless-steel material which avoid low temperature corrosion.
Inspection procedure point is set up to guarantee the sequence of expanding and welding, avoid cracking of the tube sheet holes.
4. Less fuel consumption
High quality aluminum silicate fiber is used with fire clay insulation, to control the boiler body temperature below 45℃ to control heat lost.
Sufficient steam storage room and heating area makes boiler to generate high quality steam and high thermal power.
Condenser is added to reuse the waste heat of the exhausted smoke to increase feeding water’s temperature and reduce emission temperature, which can increase the thermal efficiency above 98% and save operating cost.
He noted that in examining the total cost of typical natural gas-fired boiler systems over ten years, fuel cost typically represents 94% of the total expense, while the initial cost of the boiler represents only 4%, and upkeep and maintenance of the system is only 2%.

Author: Donna Boyle Schwartz Sep 15, 2017· The typical materials used in the industry are A53-B/C and A106-B/C carbon steel for feedwater, fuel gas, and steam. The tubes within the boiler itself are selected by the boiler manufacturer but typically will be carbon steel of seamless construction. Helical welded tubes are occasionally quoted as they are easier to fabricate.
Apr 22, 2015· These condensing boilers do require higher alloy materials of construction to combat the acidic condensate generated as the flue gas is condensed, capturing the latent heat in the flue gas. Return water temperature and total system design play a large role in the selection of the boiler and final system efficiency goal.

Regular boilers are also referred to as conventional boilers or open vented boilers. The boiler provides central heating and hot water through a separate hot water cylinder. This is usually found in a an airing cupboard and is itself fed by one of two feeder tanks which contain cold mains water.
For more on Boiler Selection Firetube. Non-condensing firetube boilers are available for low- or high-pressure steam, or for hot water applications. Typically used for applications ranging from 15 to 2,200 horsepower, a firetube boiler uses a cylindrical vessel, with the flame in the furnace and the combustion gases inside the tubes.
