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.

Alfa Laval - Waste heat recove

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.

Flue gas heat exchanger | Waste heat recovery syst

A flue gas heat exchanger can often achieve a similar result for a fraction of the costs as the complete renewal of a plant. In this way, for example, the heat lost during the manufacture of a work piece is used to preheat or keep the tools, moulds and spaces warm.

Heat recovery FAQ - Thermal Energy Internation

1. What is a FL  U-ACE hea  t recovery system FLU-ACE is a direct contact condensing heat recovery system. It recycles the heat normally lost through flue gas exhaust, and uses it to preheat a heat sink – this could be water for your space heating, domestic hot water, boiler feed water, or outside air heating. By replacing the existing load with our recovered energy, many industrial

Update: Troubleshooting exhaust problem with boilerCondensing boilers direct-vented exhaust a concernSee more results FLU-ACE is a direct contact condensing heat recovery system that recycles the heat normally lost through the boiler flue gas exhaust. The key benefits are: Reduce energy consumption on boilers by 10% to 20%; Enjoy full payback in two to four years… with continued savings throughout the …

Are passive flue gas heat recovery devices saver

Normally, flue gases escaping to the atmosphere can exceed 60°C. Passive Flue Gas Heat Recovery Devices reclaim much of this wasted heat, letting the flue gases then vent to the atmosphere much cooler. A heat exchanger is fitted around the flue coming …

Corrosive flue gas is no longer a show-stopper for he

Corrosive flue gas is no longer a show-stopper for heat recovery. A significant amount of waste heat in flue gases remains untapped due to acid dew point corrosion. Download the whitepaper to find out how to overcome this limitation.

Homemade flue heat recovery? — Heating Help: The Wa

I have seen some posts on here about heat recovery, with some problems pointed out. One was a risk of CO being formed, I'm not sure why that would happen since it wouldn't change the boiler itself, but the boiler is located outside in a separate boiler house, so if any was formed, it wouldn't be a …

Flue Gas Heat Recovery | DoItYourself.c

Any boiler which works by burning fuels to produce heat will need to have some form of vent or chimney to get rid of the fumes from the house without them causing danger. Flue gas heat recovery systems are a great help for any boiler because they will prevent a loss of heat. Boiler Basics. Almost all boilers will be powered by oil or natural gas.
