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.

Fire-tube boiler Last updated January 02, 2020 Sectioned fire-tube boiler from a DRB Class 50 locomotive. Hot flue gases created in the firebox (on the left) pass through the tubes in the centre cylindrical section, which is filled with water, to the smokebox and out of the chimney (stack) at far right. The steam collects along the top of the boiler and in the steam dome roughly halfway along
Author: powermechanical A vertical boiler with horizontal fire-tubes is a type of small vertical boiler, used to generate steam for small machinery. It is characterised by having many narrow fire-tubes, running horizontally.. Boilers like this have been widely used on ships as either auxiliary or donkey boilers. Smaller examples, particularly the Robertson type have been used for steam wagons
Jan 20, 2017· Horizontal Fire Tube Boilers. With fire tube boilers, the water surrounds the tubes that house the hot gases and flame as well as the furnace.Most fire tube boilers will range in size anywhere from 15 up to 2,200 HP as a package. These boilers have design pressures between 30 and 160 pounds for hot water and 15 - 250 pounds for steam.
Jun 13, 2013· Fuel is burned inside the furnace, which heats the water in the steam-generating tubes. The water then rises to the steam drum where saturated steam is drawn from the top of the drum. The watertube boiler has some relative advantages over the firetube boiler design, which are outlined below.
Author: Michele Tomas Introduction. WNS series horizontal internal combustion boiler is classic 3-pass wetback oil/gas fired boiler. After fuel is atomized by burner, flame is full of the wave furnace and transfer heat via furnace wall, called 1st pass; the high temperature flue gasses are collected in reversal chamber and then enter 2nd pass, which is grooved tube bundle area through heat convection, air
The efficiency of the fire tube boiler is less as compared to the water tube boiler. The efficiency of the water tube boiler is more. 14. The maintenance of this boiler is costly. It requires regular inspection. They are easy to maintain as they are externally fired. 15. Ex: Cornish Boiler, Lancashire Boiler. Ex: Babcock and Wilcox Boiler.
Summary • The firetube boiler is a versatile package suitable for a plethora of applications including heating and process • Typical size range is 100 –2500 HP • Pressures to 350# • Construction follows ASME code Sections I & IV and includes close 3rd party inspections • There are both dryback & wetback horizontal firetubes with each having advantages and disadvantages
Dec 30, 2016· A small vertical fire tube boiler is simply an old boiler with an unknown history at this point. The UT will tell you a lot. Before you get any further with that boiler, I would check your local and state boiler codes and regulations as to whether you will be allowed to put that boiler into steam service. Granted, it is a historic old boiler.
A high quality, small-size steam boiler of traditional design in heavy rivetted plate, made in the 1950's. Approx. 4 Ft high and working pressure 175 psi, with an estimated output of approx. 250 lbs/hr steam. For sale complete with various fittings, as shown. SOLD
Fire Tube Boiler Diagram. These boilers include a water level indicator; a pressure gauge, steam stop tap security tap, & a manhole like mountings for providing security as well as simplicity of working. The Fuel burns on the grate of the firebox in the boiler and the resultant hot-flue gases are permitted to flow in the region of cross tubes.
