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.
Beijing’s burning issue – reducing boiler NO x emissions. and describe the first project in China to adopt this method, As a result, 1,500 gas-fired boilers were modified in 2016. This year, Beijing plans to implement low NOx modifications on more than 7GW of gas-boiler capacity.
Area Site Boiler Size (design heat input) NOx Limit2 Rule Citation In 30 T.A.C. Statewide – requirements starting with manufacturing dates of 7/1/2002 (or 1/1/2005 where noted)
ate at less than 9 ppm NOx. In 2007, the Air District began workshops with the intent to further limit NOx emissions. With this new rule pending, J.G. Boswell approached R.F. MacDonald Co request-ing a solution that would allow the boil-ers to operate below the new limits of 6 ppm NOx and 50 ppm CO and to review energy saving options related to
The ACB-150S-N indoor residential Ultra-Low NOx Combi Boiler uses up to 150,000 BTU/hr of Natural Gas to deliver a continuous supply of hot water and space heating for a home. This High Efficiency heating system has a 95% AFUE and is ENERGY STAR Certified.
Low NOx burner retrofits to an existing boiler, dryer or incinerator aren't as simple as pulling out the old burner and bolting in a new one. There is so much more that needs to be considered as

Lower Emissions with Low NOx Boilers Manufacturer. 2019-3-20 · Low NOx boilers can utilize several design and equipment solutions to significantly reduce overall nitrogen oxide (NOx) emissions and reach levels under 30 ppm: Low NOx Burners – Low NOx boiler burners are designed to maintain stable combustion at lower flame temperatures and
Ultra Low NOx Boilers to meet the strictest compliance requirements. Many state air quality compliance regulations require low NOx boiler emissions below 30 ppm. And in some parts of the country like California, Texas, Louisiana and New Jersey, boiler operators are required to achieve and maintain even more stringent air quality emission
Dec 13, 2016· The latest models are designed, constructed and tested to meet the European boiler standard EN15502 Pt 1 2015 Class 6 – achieving NOx emissions as low as 35 mg/kWh. They also qualify for maximum credits for low NOx space heating from the sustainable building assessment scheme BREEAM, helping improve a building’s environmental ratings.
