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 water-tube boiler is those boiler in which the water is present inside the tubes and fire or hot gases surround these fire tubes. The examples of water tube boilers are a La-Mont, Benson, Stirling, Babcock and Wilcox, Yarrow and Loeffler boiler.
Watertube boilers are safer by design and generally can operate many years longer than firetube boilers. Watertube boilers are available in larger capacities and recover faster than firetube boilers. Watertube boilers can also handle higher pressures (up to 5000 psig), and have the ability to reach very high temperatures with the use of
May 20, 2020· Difference Between Watertube and Firetube Boiler Difference between fire tube boiler and water tube 1:12. The Difference between Wetback and Dryback Boilers - The Boiling Point - …
Jun 05, 2018· Comparison between Fire Tube and Water Tube Boiler can be done in 14 aspects. Those aspects are operating pressure, passage of material type in tubes, rate of steam generation, handling of load fluctuation, floor area requirement, efficiency, operator skills, design, maintenance cost are listed below in the tabular form.
Author: Michele Tomas Condensing boilers are on average 40-50% more expensive than conventional types. However, the difference in cost, from conventional to condensing boilers, can be recovered in somewhere between a few months to 4 years (depending on the efficiency of the original boiler installation, boiler utilisation patterns, costs associated with the new boiler installation, and how frequently the system is
The main difference between firetube boilers and watertube boilers is explained by their names. In a watertube boiler, the heating element acts directly on tubes filled with water, which run through the furnace casing, to produce the needed steam or super-hot water.
Understanding the operational design differences. Firetube boilers are available in either dryback or wetback design. They are identified by the type of reversal (turnaround) chamber, or posterior portion of the combustion chamber, through which flue gasses travel through the furnace to second-pass tubes to heat water within the boiler.
Jun 13, 2013· However, from a manufacturing standpoint, firetube boilers are typically lower in cost than a comparable sized watertube boiler, the firesides are easier to clean, and the straight firetubes are easily replaceable. Let’s not forget that there is a tremendous difference in water volume between a firetube boiler and a watertube boiler.
There are a number of considerations to factor when determining the best boiler for your steam generation needs like operating pressure, steam pounds/hour output, demand fluctuation, general application requirments and total cost of ownership, etc. Two primary boiler types, the firetube boiler and the watertube boiler, are essentially opposite in design. The firetube boiler passes combustion
Apr 23, 2016· The difference between fire tube boiler and water tube boiler can be done on various points. These points includes types of fluid flows within the tubes, steam generation rate, floor area required for the steam generation, transportation, efficiency, fluctuating loads, operating cost etc. the knowledge of the difference about these two boiler is very crucial.
