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.
Oct 26, 2017· For residential and commercial/industrial purposes, there are 2 types of boilers. The most common is the fire tube design. This would include the common sectional type boiler seen in most residential applications. The fuel is burned, and the hot gases pass through a series of flue passages or tubes that are generally steel.

Fire tube steam boilers. ZG Group is engaged in offering a wide range of Fire Tube Steam Boiler.It is extensively used to remove hardness from water and divalent cations of calcium or magnesium from water. the fire tube boiler consists of numbers of tubes through which hot gasses are passed. these hot gas tubes are immersed into water, in a closed vessel.
(i) Fire Tube Boiler: In fire tube boiler the fire or hot gas are present inside the tubes and water surrounds these fire tubes. Since fire is inside the tubes and hence it is named as fire tube boiler. The heat from the hot gases is conducted through the walls of the tube to the water. (ii). Water Tube Boiler: In water tube boilers, the water
The universal type of steam boilers is the smoke tube or fire tube boiler where the heat and gases of combustion (from furnace) pass through tubes that are enclosed by water. While in water tube boilers, water passes through tubes. Mostly used boiler in small and medium industries with different fuels and steam pressure requirements. Types of

Nov 24, 2016· Fire Tube boiler is the simplest form of the internal furnace, vertical fire tube boiler.Fire tube boilers are a portable boiler and it requires a small floor space. The steam rating in fire tube boilers doesn’t exceed 2500 kg per hour and pressure is limited to 10 bars.
Aug 30, 2019· The water tube boiler generates more steam of high pressure whereas a fire tube boiler generates steam of low pressure. We will discuss the fire tube boiler, different types of firetube boilers, defects, and uses. Fire Tube Boiler. In Fire Tube Boilers, hot flue gases will be flown inside the tube and these tubes are surrounded by water. These
For fire tube boilers, wns type oil gas fuel boilers are the most widely used. For water tube boiler, there are many types, such as D type water tube boiler, fluidized bed type water tube boiler, traveling grate type water tube boiler. They are all different with each other.
