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.
As the name suggests in a smoke tube boiler, the flue gas passes inside tubes, surrounded by a water mantle cooling the smoke tubes. The boilers are normally mounted vertically and generally have three tube passes with between 300 and 800 tubes inside the boiler…
The SB-ST Type 3 gas passes Smoke Tube Packaged Boiler adopt the Corrugate design in order to cope with the thermal expansion effects as well as to maximizethe heat transfer efficiency. Such a type of 3 gas passes Smoke Tube Packaged Boiler is easy to erect and ensures the High Thermal Efficiency with the adoption of wet back type chamber structure design.
Puff, Puff. Improper burning is the cause of black smoke coming from a boiler. If the oil does not burn normally, it will produce a dark-colored smoke that may be seen from the rooftop vent or
It is best known from its popularity in model engineering, as a multi-tube boiler that's relatively easy to construct. The boiler consists of two concentric drums with a waterspace between them. Fire-tubes pass through this drum, arranged symmetrically around the diameter. The entire boiler is wrapped in a cylindrical smokebox.
It is a conventional 3 pass smoke-tube design, designed for the combustion of coal and wood in an internal furnace and is therefore sometimes known as coal/wood fired Steam Boiler. This Packaged Boiler comes in dry back, semi-wet back, and fully wet-back options and is most suitable for a manual firing of Solid Fuel like coal, wood or briquettes.
Smoke tube boilers are heavy in comparison to the water tube boilers. Fire Tube Boilers. Fire tube boilers are the backbone of low pressure steam and hot water applications. The flue gases pass through the furnace and various smoke tubes. Typically, such boilers provide saturated steam or hot water. However, superheated steam supply is possible. With ERK Tubes such boilers can be very compact and low cost.
In this boiler products of combustion [flue gases] , the combustion that takes place inside the … Difference on Features 1. Smoke tube boilers have a simple structure and a large volume of water and steam and good adaptability to changes in 2. The pressure of water tube boilers can adapt to a wider scope, even can break through the pressure limit and meet 3. The capacity of most smoke tube
