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.

The direct vent, sealed combustion boiler features a fully modulating, stainless steel burner and is environmentally friendly with LoNox operation.
Shifting to real time efficiency monitoring can improve the boiler efficiency significantly depending upon the boiler type and actual conditions at site. In nutshell, monitoring and maintaining the boiler efficiency for the overall operational life of the boiler is a must to cut fuel bills and reduce carbon footprint.
BOILER EFFICIENCY BOILER EFFICIENCY GUIDE. FACTS. Forward Today’s process and heating applications continue to be powered by steam and hot water. The mainstay technology for generating heating or process energy is the packaged firetube boiler. The packaged by manufacturing the highest efficiency and highest value products in the industry. We
As the leader in home heating equipment, U.S. Boiler Company manufactures several oil-fired boiler solutions, including the award-winning MPO-IQ™ 3-pass high efficiency oil boiler, and MegaSteam™, the most efficient cast iron residential oil-fired steam boiler in the world.
When you are looking for a new commercial steam boiler system, you will expect a clean, efficient and safe solution that is compliant with all relevant regulations. At Viessmann, we provide high efficiency steam boilers that meet all of these requirements and are suitable for a wide range of production facilities.
Likewise an In-Service Efficiency of a boiler at 100% load, (meaning full fire 24 hours per day, 365 days per year) will be equal to Boiler Efficiency. However, drop the steam load to 25%, (i.e. full fire for six hours and idling for 18 hours) and the In-Service Efficiency will be much lower than 78.5% efficiency.
New High Efficiency Boilers From Bryan Steam. Bryan Steam has introduced the HE-AB Series of forced draft gas fired “Flexible Water Tube” Water Boilers with a guaranteed efficiency of 85%. The high combustion efficiency results from a uniquely designed integrated extended surface heat extractor.
Apr 09, 2018· In marine practice 60bar 510C superheat is common, but I believe there are 120–150bar boilers in circulation. A quick glance at steam tables for 120bar shows this to be 325C saturation temperature, so depending on the degree of superheat required,
Author: Tim Seberger The combustion efficiency increases with increased excess air - until the heat loss in the excess air is larger than the heat provided by more efficient combustion. Excess air to achieve highest possible efficiency for some common fuels: 5 - 10% for natural gas; 5 - 20% for fuel oil; 15 - 60% for coal; Carbon dioxide - CO 2 - is a combustion
