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.
Converting an existing boiler is typically 15% to 30% of the cost of installing a new natural gas boiler. Additionally, converting coal boilers to firing natural gas provides the following major
(inert) gas in LFG is equivalent to the inert gas entering a boiler when about six percent of the flue gas is recirculated to the boiler. Flue Gas Recirculation (FGR) is a widely applied technique for reducing nitrogen oxide (NOx) emissions from natural gas-fired industrial and commercial boilers,
design aspects from the natural gas supply header through the boiler outlet. Topics include FEGT, radiant superheater absorption, spray attemperation, back pass absorption, and potential pressure part modifications. Wall-fired and T-fired PC boilers as well as stoker …
gas passage nature of boiler. By zozen Product 0 Comments. Draft (boiler) – Wikipedia. The difference between atmospheric pressure and the pressure existing in the furnace or flue gas passage of a boiler is termed Natural draft: When air or flue gases flow due to the …
Lower the Stack Temperature. Lowering stack temperatures may be as simple as a day/night set … Gas boilers are central heating systems that use liquid propane or natural gas to provide heating throughout a residential or commercial building. With all the top brands and styles available, you can find the perfect gas boiler today on eComfort.
H.Ö. Paksoy, B. Beyhan, in Advances in Thermal Energy Storage Systems, 2015. 220.127.116.11 Switzerland. In Geneva, Switzerland, a study was undertaken to compare three greenhouses with different heating systems; one conventional using a natural gas boiler, one with a tank storage system, and the other with an underground, borehole storage system .It was concluded that the storage systems did
Sep 29, 2016· Draught Draught is defined as “the pressure difference (between absolute gas pressure at any point in a gas flow passage and the atmospheric air outside the boiler) required to maintain flow of air and exhaust gases through the boiler setting.” Function of draught: 1.
The Peerless® PUREFIRE® Series gas-fired condensing boiler from PB Heat, LLC is a high-efficiency 95% AFUE boiler for residential applications and is available for either natural or LP gas systems. The direct vent, sealed combustion boiler features a fully modulating, stainless steel burner and is environmentally friendly with LoNox operation.
A condensing boiler makes the most sense with radiant heat, though baseboard and conventional radiators work well also. Steam radiators do not AFAIK offer themselves to be heated via condensing boilers. Note, there is a strong preference away from condensing oil boilers due to the corrosive nature of US fuel oil (condensing gas boilers are OK).
A boiler or steam generator is a device used to create steam by applying heat energy to water.Although the definitions are somewhat flexible, it can be said that older steam generators were commonly termed boilers and worked at low to medium pressure (7–2,000 kPa or 1–290 psi) but, at pressures above this, it is more usual to speak of a steam generator.
