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.
Figure 1. Condensing boiler with an indirect DHW system and outdoor reset control . Condensing boilers achieve high efficiencies because they can recapture the latent energy from the moisture in the combustion gases when those gases condense. For condensing to occur, the boiler’s heat exchanger surface temperature must be

Dec 01, 2015· I have a vaillant combi and i have had the heating set at 60C. However i have just had a new main combi installed on a property i rent out and we had the heating on 80C (its max) to see how it performed this aft. Well the house really got hot quickly and the rads were too hot to touch. I was
ENERGY STAR Most Efficient 2020 — Boilers. The ENERGY STAR Most Efficient 2020 designation recognizes the most efficient products among those that are ENERGY STAR certified.These exceptional gas and oil boilers represent the leading edge in energy efficient products this year.
Jan 22, 2020· If you've got a condensing boiler, you may not be getting the full energy savings. Follow our guide to correctly set your water temp for the best efficiency.
File Size: 296KB Mar 19, 2008· In a cold snap, I will raise the temp to 175 or 180, to get more heat storage in the boiler water, and heat demand really goes up here below 20 degrees F. I keep the temperatre lower for several reasons, mainly becasue we have a tile and wood floor, and …
Mar 23, 2019· A 4 Ton Boiler shall produce 4000kg/hr of steam (From and At 100 deg.C) i.e. if water is fed at 100 deg.C and steam is drawn at 100 deg.C. If we feed water at ambient temperature and draw steam at 150 psig then the Boiler capacity shall be derated
Pre-heating the feed water to achieve an ideal boiler feed water temperature will allow the boiler to run most efficiently as the heat input required to raise the temperature of the water up is reduced. The difference between 140°F and 180°F in boiler feed water temperature equates to about a 3-4% difference in boiler efficiency.
5 gpm coil is a bit of a joke in most boilers.. The imput determines the output . You would need around 300K of input to get 5gpm of hot water output. The hot water production depend on input , unit eff and incomming water temperature to temp rise or gpm x 8.3(weight of 1 gallon of water in # ) x temp rise x 60 min = net Btu's Example.
