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.
Characteristics of boiler feedwater. Water has higher heat capacity than most other substances. This quality makes it an ideal raw material for boiler operations. Boilers are part of a closed system as compared to open systems in a gas turbine. The closed system that is used is the Rankine cycle. This means that the water is recirculated
Oxygen removal from boiler water in high pressure boilers Abstract The most frequently encountered corrosion problems results from exposure of boiler metal to dissolved oxygen. Breakdown of the magnetite layer is almost because of mechanical and thermal stresses induced during boiler start up …
You want to get the most out of each day. But your life doesn’t take a break to let you recover. We’ve got you. We’re OXIGEN. Water with an O 4 edge. Two O 2 molecules fused together to create our proprietary O 4 molecule. Extra oxygen that stays stable in water until you drink it.
Glucose oxidase and catalase co-immobilization on biosynthesized nanoporous SiO2 for removal of dissolved oxygen in water: Corrosion controlling of boilers. Journal of Industrial and Engineering Chemistry 2014, 20 (4) , 2378-2383. DOI: 10.1016/j.jiec.2013.10.016.
the baseline system and the annual energy use by the heating system after the implementation excess O 2 control measures. In all cases involving excess air reduction, an essential step is to determine the amount of excess O 2 present in the flue gas during normal operating conditions before and after implementation of the measure.
File Size: 117KB NOTE: Because some boilers operate with a very high percentage of excess oxygen, it is common for the first year savings to be substantially higher than this. However, much of that savings can be attributed to a more reasonable manual tuning of the boiler, and not necessarily from the installation of an automatic O2 control system.

system refers to deaerator, feedwater pumps, and the piping to the boiler. Before water enters the boiler, oxygen must be removed or corrosion can occur throughout the boiler system, forming pits that eat away at the metal. Resulting leaks could lead to a blown boiler tube and ultimately could cause a …
Oct 10, 2017· Oxygen matters. Every living organism on earth needs it in one form or another. While a high efficiency condensing boiler isn’t necessarily a living thing, it does work in a system that requires appropriate amounts of oxygen to operate at optimum levels.
Galvanic corrosion. Caustic corrosion. Acidic corrosion. Hydrogen embrittlement. Oxygen attack. Carbon dioxide attack. Without proper mechanical and chemical deaeration, oxygen in the feed water enters the boiler. Much is flashed off with the steam; the remainder can attack boiler metal.
