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.

Hotspots on Furnace Tubes | KLAY EnerS

Hotspots usually can be detected with a periodic high temperature IR scan of the furnace tubes using an adequate ranged high temperature imaging camera. Irregularities in tube skin temperatures can be detected and approximate tube skin temperatures can be measured (Accurate measurements however are always difficult if not impossible to measure

Finding the Root Cause of Boiler Tube Failur

Contact Us · Engineered Solutions · Safety · Efficiency Upgrade · Burner Services · Tube Bending Components typically affected: This type of boiler corrosion fatigue is commonly found on furnace wall tubes of coal-fired once-through boiler designs, but has also occurred on tubes in drum-type boilers. Solutions: Reduce the ramp rates during start-up and shut-down to reduce the thermal stresses. Optimize sootblowing operations to minimize

Marine Boiler Furnace Inspection - Bright Hub Engineeri

Dry cracks in the furnace mouth, crown, or the furnace tubes caused by flame impingement are possible due to scale encrustation at the water side and forcing of the boiler. Areas suffering from poor circulation or relatively uncooled area are also susceptible to the above failure. Deep cracks in the furnace mouth, crown, or furnace tubes caused by flame impingement are possible due to scale
