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.
Steam Production From steam tables we can see that the total heat of steam does not vary a great deal as the boiler pressure increase The boiling point (b.p.) increases as the pressure increases Thus the sensible heat increases as the pressure increases, and the latent heat decreases Boiler pressures are expressed in psia, psig, bar, kg/cm2
File Size: 296KB Electric steam boilers commonly offer the option of installing a clean steam generator as a shell-type boiler. In this case all medium-bearing parts are produced from stainless steel. In some countries the electrical energy tariffs are very low, meaning that the use of an electric steam boiler makes sense for financial reasons.
Steam Boilers: Horizontal Three Pass Firetube • Vertical Firetube. Aldrich Company manufactures three pass and vertical firetube steam boilers for low pressure applications. The Classic Series modified Scotch Marine “Scotch Box” boiler is designed to fit through a standard doorway.
The GB300 Series cast iron boiler is ideal for commercial hot water or steam heating systems. Appreciated for its simplicity and relatively rare need for routine service, seventeen sizes are available ranging from 400 MBH up to 2,000 MBH with high efficiencies.
performance of a replacement steam boiler and should always be considered as part of the boiler installation. Always be sure to include clean-out and skimming tees in the near boiler piping. These "Tees" are necessary for proper cleaning and servicing of the boiler. • …
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 firetube boiler has proven to be highly efficient and cost effective in generating energy
