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.
Types of Exhaust Gas Boiler (EGB) Fires and Ways to Prevent Them An Exhaust Gas Boiler is a type of heat recovering system on ships which allows the exhaust heat of the main engine to produce steam while going out in the atmosphere.
EGB stands for Exhaust Gas Boiler. EGB is defined as Exhaust Gas Boiler rarely. Fire in exhaust gas boiler – GARD. Feb 1, 2006 – The following incident involving a fire in exhaust boilers occurred on board a bulk carrier a few years ago. The vessel berthed and the main … T-Q diagram for exhaust gas boiler (EGB) – Figure 2 of 7
Exhaust Gas Boilers The Clayton Heat recovery boiler operates on the same tried and tested principle as the world famous Clayton Steam generator. It is therefore the most compact, efficient, responsive and safest means of producing high quality steam or hot water from waste gas streams.
Exhaust Gas Boilers also known as Exhaust Gas Economizers, with extended heating surface, used for waste heat recovery in motor ships. A diesel engine loses approximately 30% of the energy to the exhaust gases. A turbocharger recover some of it, but there is still heat losses that can be recovered by means of an Exhaust Gas Boiler, EGB.
With the EGB system a smaller MAN turbocharger is used to have higher efficiencies at lower engine loads. To enable operation in high engine loads the turbocharger needs to be saved of overspeeding and therefore some exhaust gas will be bypassed beyond the turbocharger. Nice effect in higher loads is also higher exhaust gas temperatures.
How is Exhaust Gas Bypass (engine technology) abbreviated? EGB stands for Exhaust Gas Bypass (engine technology). EGB is defined as Exhaust Gas Bypass (engine technology) frequently.

Dec 09, 2015· Exhaust gas boiler (EGB or EGE) or economiser described in this article is a smoke tube boiler with steam space, used for heat recovery from main engine exhaust gas. An illustration of the boiler is shown in figure below. The exhaust gas boiler is designed as a vertical boiler with a cylindrical shell surrounding the boiler tubes and water drum
Exhaust Gas Boilers And Economisers working procedure The use of exhaust gases from diesel engine: The use of exhaust gases from diesel main propulsion engines to generate steam is a means of heat energy recovery and improved plant efficiency. An exhaust gas heat exchanger is shown in Figure above.
