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.
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.
Feed-water purity requirements therefore can vary widely. A low-pressure fire-tube boiler can usually tolerate high feed-water hardness with proper treatment while virtually all impurities must be removed from water used in some modern, high-pressure boilers. Only relatively wide ranges can be given as to maximum levels of alkalis, salt, silica
Jul 19, 2019· Generally, Power plants require steam for the purpose of heating. Hence, this purpose is fulfilled by the boiler, where the steam is produced by boiling water. Basically, the steam is produced by boiling water beyond its boiling point where it changes its state from liquid to vapor and this vapor is known as steam.
Feed water enters the top rear drum, passes down the rear tubes to the mud drum. Steam and boiler water go up the front and center tubes to the front and center drums. Circulating tubes allow boiler water to pass between the drums. What does not go out as steam goes back down the rear tubes.
explain difference between water boiler and fire tubed . If you Don't Understand anything in this video .Comment below I will explain : Brilliant Mind: 3.4KDifference between Fire Tube Boiler and Water Tube Boiler https:// I am going to tell you difference between fire tube boiler and water tube boiler. The boiler is divided into two main types.
Difference between Fire Tube Boiler and Water Tube Boiler . Mar 19, 2016· The main difference between fire tube and water tube is that in fire tube boiler the flue gases flow in the tubes and water flows from the shell and in water tube boiler, water flows from the tubes …

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.
beyond the dew point; adding to its efficiency at low fire. 2) The condensing boiler normally has more fireside heating surface than the non-condensing boiler (because it doesn’t want to condense); therefore, more efficiency gain, and lastly, 3) If the boiler is able to control its excess air level at low fire, similar to our Clearfire series of
Steam boilers may utilize a condensing economizer to gain the same energy from the flue gas, but are theoretically unable to capitalize on this design inside of the boiler due to the difference between boiler water temperature and boiler exhaust dew point.
fire tube boilers, water tube boilers- Boiler. What Is The Difference Between Fire Tube Boiler and Water Tube Boiler 2016-05-13 When determining a boiler for your project, etc. There are two main boiler types that you can choose from for your specific application: water tube boilers and fire …
