Introduction of WNS gas / oil fired steam boiler:

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.

Technical advantages:

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.

Boiler Water Chemicals | Steam Boiler Water Treatmen

Boiler Water Oxygen Scavengers. A chemical oxygen scavenger is used to remove the residual oxygen from the boiler feed water in order to protect not only the boiler but also control corrosion in the hotwell (or feed tank) and the condensate return lines.

Chemical Treatment Requirements for Steam and Hot Wat

Jun 12, 2017· Boilers, in one form or another, have been used for centuries to produce steam for heat and power. Today, boilers produce steam to drive electric turbines, heat buildings, and provide power for countless industrial and commercial applications. Although the steam uses may vary, the importance of maintaining the water quality in these systems remains the…

Boiler Scale - How To Clean Scale Off Of Your Steam Boil

How To Clean Scale From Your Boiler It is difficult to get enough circulation and velocity to all parts of the boiler to remove all the scale. If cleaning is successful, immediately refill the boiler with water and add chemicals to get pH to 11 and sulfite to 200 ppm. Replace manhole and have operator re-fire the boiler and bring to
