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.
With the flue gas temperature increasing from 300 °C to 600 °C, the regeneration capacity of the system increases, thus more vapor contained in the flue gas can be recycled and the water recovery of the system increases from 46.5 g/s to 58.8 g/s as shown in Fig. 3(a).
Alfa Laval Aalborg offers a series of highly efficient waste heat recovery boilers that extract heat from hot flue gases and generate steam or hot water. A boiler is easily added to your flue gas stream and recovers heat that would normally be released into the air through a chimney. There are many possibilities to profit from recovered heat.
RECOVERY OF WATER FROM BOILER FLUE GAS FINAL TECHNICAL REPORT January 1, 2006 to September 30, 2008 by Edward Levy Harun Bilirgen Kwangkook Jeong Michael Kessen Christopher Samuelson Christopher Whitcombe Report Issued: December, 2008 DOE Award Number DE-FC26-06NT42727 Energy Research Center Lehigh University 117 ATLSS Drive Bethlehem, PA 18015
This project will demonstrate ConDex boiler flue gas and water recovery technology at Imperial’s Kearl Oil Sands mine. The ConDex technology is designed to reduce greenhouse gas (GHG) emissions by capturing and using exhaust heat otherwise lost to the atmosphere through the flue gas streams in oil sands mining operations.
The Aalborg AV-6H exhaust gas boiler is a water tube boiler for heat recovery, typically after gas engine. The boiler comes in a horisontal layout and compact work-shop assembled module. It is easy and fast to install while allowing maximised access for convenient maintenance and service. • High-efficient counterflow design for heating of hot
Apr 16, 2020· This project dealt with use of condensing heat exchangers to recover water vapor from flue gas at coal-fired power plants. Pilot-scale heat transfer tests were performed to determine the relationship between flue gas moisture concentration, heat exchanger design and operating conditions, and water vapor condensation rate. The tests also determined the extent to which the condensation …
Nov 29, 2016· A device known as SAM4 can recover waste heat in flue gases and make it available as low pressure steam. Of particular interest to first generation ethanol p
FGHRS recover heat from waste flue gases to preheat the cold water entering the boiler, lowering the amount of energy needed to warm the water up to the required level. Almost all modern boilers already have some sort of heat recovery built in, making condensing boilers much more efficient than older ones.

The recovery of heat from the flue gas is an effective way to improve the thermal efficiency of a boiler. In a coal-fired boiler with wet-desulphurization, a portion of the flue gas thermal energy is used for the latent heat process, which leads to temperature reduction and humidity increase.
