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.
In a condensing boiler system, however, the return water temperature should be kept low in order to condense the water vapor and capture the latent heat from the boiler exhaust. The heat exchangers of condensing boilers are designed and manufactured for this.
In a condensing boiler, heat existing in the flue gasses can be captured and ‘recycled’ back into the heating system and used to preheat the cold water entering the boiler. During this process, the temperature of the flue gas is rapidly reduced from around 130℃ to 50℃.
The condensing boiler recovers some of this heat energy by condensing the water vapor in the exhaust fumes. This water vapor passes through a condenser exchanger: the vapor then sublimates into the water and releases heat which is immediately transmitted to the hot water circuit of your commercial or industrial building.
Dec 17, 2017· The best you can do is optimize your condensing boiler for your buildings, climate and heating systems. Optimizing your condensing boilers. Design. Condensing boilers perform at peak efficiency at cooler temperatures because more condensation can occur. Designing an entire system that runs on cooler water will maximize the efficiency of the boiler.

95% AFUE Stainless Steel Modulating Condensing Boiler with standard features such as ASME fire tube heat exchanger, boiler circulator, 5:1 turndown ratio, multi-color graphic LCD display, Smart System Control Featuring: three programmable zone temperatures, outdoor …
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
Condensing boilers are water heaters fueled by gas or oil. They achieve high efficiency (typically greater than 90% on the higher heating value) by condensing water vapour in the exhaust gases and so recovering its latent heat of vaporisation, which would otherwise have been wasted.This condensed vapour leaves the system in liquid form, via a drain.
Author: Joanna R. Turpin The first step in optimizing boiler efficiency in Landry’s eyes is to better get to know your system. Testing is critical to optimize boiler efficiency. “As you get to know the performance of both (your primary and backup) boilers, you may notice that with the large duty boiler, you’re getting quite a lot of radiation heat losses when it
With a wide range of options for both existing homes and new construction, you'll find that Rinnai condensing gas boilers offer features such as on-board display and an outdoor reset sensor to continually adjust to changing temperatures and optimize performance. BEST CONDENSING BOILER FOR YOUR NEEDS. In addition to continuous heat throughout
For a boiler to qualify for ENERGY STAR®, the product must meet or exceed the EPA’s minimum efficiency ratings. For gas boilers, both the Alpine™ and K2™ boilers are ENERGY STAR® certified. Upgrading an 80% efficient boiler to our 95% efficient Alpine™ boiler or K2™ boiler can provide about a 15-20% savings in energy costs.
