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.
HoSt supplies cylindrical flame tube boilers. In this type of boiler the shell is filled with water and the flue gasses flow through the flame tubes. For improved cleaning, the first part of the boiler is equipped with a radiation section where the flue gasses are being cooled before they flow though the flame tubes.
A 3-pass firetube boiler design consists of three sets of horizontal tubes, with the stack outlet located on the rear of the boiler. A downdraft design keeps the cooler water from having an effect on the hot surfaces within the boiler.
Shell boilers, also called flame tube boilers or flue tube boilers, are a robust type of boiler with a long service life. Modern shell boilers, which may be single or double Cornish boilers, cover the capacity requirements up to 60 t/h of steam with pressures up to 30 bar. They are used in almost all sectors of industry to generate

As hot water boilers, ﬂame tube boilers deliver up to 20 MW. In the steam boiler version they offer an output of up to 28 t/h, depending on type. Vitomax D double ﬂame tube boiler The Type D Vitomax double ﬂame smoke tube boilers deliver saturated or hot steam at a rate of 12 to 58 t/h and warm or hot water from 10 to 38 MW.
Steam boilers With four different Universal type boiler designs, either as single-flame tube or double-flame tube boiler, we offer a seamless product range to meet any steam requirement. Bosch steam boilers generate process heat with output ranges from 175 to 55,000 kilograms per hour and are universally applicable.
BBS double flame tube three-pass hot water boilers are used for the generation of large heating outputs for industrial and communal projects. The double flame tube three-pass hot water boilers are available both as low temperature boilers with supply temperatures of 120 °C (115 °C ) and as high temperature boilers with temperatures of up to 230 °C.
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
