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 design of shell and tube heat exchanger using Kern method for water and steam combination is validated by well-known Dittus-Boelter equation of turbulent flow inside tube. The analysis is extended using the above Kern method with different fluid combinations such as …
A fire-tube boiler is a type of boiler in which hot gases pass from a fire through one or (many) more tubes running through a sealed container of water. The heat of the gases is transferred through the walls of the tubes by thermal conduction, heating the water and ultimately creating steam.. The fire-tube boiler developed as the third of the four major historical types of boilers: low
Sep 29, 2015· Industrial boilers provide steam for processing and heating in a wide range of facilities, from hospitals to food manufacturing to chemical plants. Fire tube-design boiler systems are very typical for this service, where the heat from the fuel pas
A coil type boiler is water tube design, the water travels through the coil and is surrounded with flue gases. The steam generated is directly fed to the process. There is no scope for steam storage as these are once through type boiler. Shell and tube type boilers have adequate steam space above the normal water level of the shell.

Abstract Pressure vessels components are widely used in the thermal and nuclear power plants for
B&W's radiant boiler designs accommodate pulverized coal, including difficult-to-burn coals, natural gas and/or oil and combustible byproduct gases. Subcritical pressures range usually 1800 to 2600 psi (12.4 to 17.9 MPa) and superheater and reheater outlet temperatures as required, usually in the range of 1000 to 1050 F (538 to 566C).
Horizontal Return Tubular Fire Tube Boiler. As one of the oldest and most simple designs for … Regular Boiler Configurations. There are two common types of boilers: Fire-tube Boilers; Water-tube Boilers; Fire-Tube Boilers. A fire-tube boiler’s principal elements include a cylindrical shell, a set of tubes, a feedwater channel line, and a combustion gas vent stack.
Design of an industrial boiler At full capacity a boiler of this size converts 3 000 litres of fuel oil or a the ﬂue gases, these boilers are also called three-pass shell boilers. Industrial boiler systems can cope with much higher pressures than pressure cookers. These

Boiler design is the process of designing boilers used for various purposes. The main function of a boiler is to heat water for steam generation. Steam produced can be used for a variety of purposes including space heating , sterilization, drying, humidification and power generation. The temperature or condition of steam required for these applications is different, so how to design a boiler …
