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.
Multiple projects 2012 thru current. Waste heat boiler inspect and repair projects. Scope of work included UT surveys, overlay of tubes, removal/replacement of single tube replacements, removal/replacement of division walls in the hopper, vertical Expansion Joint replacement, Horizontal Expansion Joint replacement, miscellaneous code piping repairs in the boiler boundary limit, and
We supply reformed gas waste heat boilers for gas inlet temperatures of up to 1,200°C and steam pressures of up to 160 bar (16,000 kPa). The reformed gas waste heat boilers for high-pressure steam are designed and manufactured with a specially developed and patented stiffened tube sheet systems.
Waste-heat boilers rely mainly upon convection for heat transfer. For high rates of transfer, gas velocity and draught loss are both high. Consequently an I.D. fan is usually installed with a waste-heat boiler. 2 Heat in Steam Produced
Optimus unfired waste heat boilers recover valuable BTU’s from hot process gas or gas turbine exhaust. The boilers are designed and constructed to Section I of …
Waste Heat Boiler www.WasteHeatBoiler.com. What is a Waste Heat Boiler?. Waste heat boilers are a special type of boiler that generates steam by removing the heat from a process that would have otherwise been wasted.. Waste heat boilers are therefore able to provide significant reductions in fuel and energy expenses, as well as reduce greenhouse gas emissions.
Apr 17, 2020· A waste heat boiler of the water-tube design is able to cope with much higher pressures of steam than a fire-tube boiler, but it is more difficult to construct and install. Inside this type of boiler, there are narrower tubes than inside a fire-tube boiler, and the tubes contain water instead of hot gases.
Cited by: 15 RD&D to advance waste heat recovery technologies. Technology needs are identified in two broad areas: 1) extending the range of existing technologies to enhance their economic feasibility and recovery efficiency, and 2) exploring new methods for waste heat recovery, especially for unconventional waste heat sources.

Firetube boilers work by forcing exhaust gases through tubes immersed in water and represent the most economical means of generating steam from waste heat. E-Tech firetube boilers are generally used to generate steam from engine, thermal oxidizer and furnace exhaust.
Waste heat boilers utilise the heat in flue gases from combustion processes or hot waste air flows from industrial processes to generate hot water or saturated steam. Due to economic and legislative considerations, waste heat boilers are frequently used in conjunction with gas turbines and combined heat and power units.
