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.

Condensing Boilers Condensing boilers are water heaters fueled by gas or oil. They achieve high efficiency (typically greater than 90% on the higher heating value) by using waste heat in flue gases to pre-heat cold water entering the boiler. Water vapor produced during combustion is condensed into liquid form, which leaves the system via a drain.
With non-condensing equipment typically manufactured from lower-quality materials (copper, cast iron, carbon steel, etc.), system designers must rely on ancillary components, such as dedicated boiler pumps, mixing valves, and temperature-averaging components, to pre-warm entering water to above 140°F.
Whether it's consistent heat throughout a home, pleasant humidity levels, or continuous hot water, Rinnai's line of Condensing Boilers keeps comfort with exceptional performance and efficiency. Our advanced smart system technology even includes an outdoor reset sensor that continually adjusts to changing temperatures.
Aug 13, 2018· A high efficiency, gas-fired condensing boiler is one of the most economical and clean ways to heat your home, reduce your monthly heating bills, and lessen environmental impact. In most circumstances, a condensing boiler can be used to replace an existing boiler in an older heating system. What makes a condensing gas boiler so efficient?
Dec 02, 2019· The efficiency difference between a conventional and condensing boiler is to the tune of 75% efficiency vs. 90% efficiency. However, older conventional boilers can sometimes run at barely more than 50% efficiency, so a move from an older boiler to a condensing boiler can potentially save you 50% of your energy bill.
Condensing Boilers Highly-efficient condensing boilers from Bosch. These boilers deliver reliable heating and hot water with high efficiency and low operating costs.
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 16, 2013· By operating the condensing and noncondensing boilers in a lead-lag sequence based on outdoor air temperature and hot water temperatures, a hybrid system provides the combined benefit of operating at maximum system efficiency using condensing boilers while significantly reducing the initial investment of an all-condensing boiler plant.
A combi boiler, also known as a combination boiler, is a type of condensing boiler. Combi boilers are highly efficient and compact, making them ideal for smaller homes. The name Combi comes from the fact that these boilers are able to act as both a water heater and also a central heating unit.
Navien condensing combi-boiler technology provides 95.0% AFUE, recognized by Energy Star as Most Efficient. These extremely efficient and eco-friendly units provide extra energy savings over a traditional floor standing boilers and storage tanks.
