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.
SL NO: Advantage: 1. The maximum working pressure of the water tube boiler is 250 bar. 2. Overall efficiency is up to 90% with an economizer. 3. It requires less floor area for a given output.
Disadvantage 3: Slower water rate. Since a combi-boiler draws its water directly from the mains and not a water tank, you may find a combi-boiler requires more time than a traditional boiler in order to fill a bath. Disadvantage 4: If a combi-boiler breaks down, you lose hot water and central heating
Advantages and Disadvantages of Water Tube Boilers 2015-11-04 08:57:36. There are two main boiler types that people can choose from for their specific application: water tube boilers and fire tube boilers.Of the two, water tube boilers contain wider range than fire tube boilers and they are …
Advantages of fire tube boiler: 1. The water is supplied in shell and outside tubes while hot gas is supplied inside tubes so the water volume can not be shaken easily when the fire tube boiler is running. 2. Fire tube boiler is so easy to use, operate, clean and maintain 3. Fire tube boiler can be used in small scale industries. 4. Fire tube
Oct 13, 2017· There are several good answers here but I think most of them are missing the two biggest reasons. The first is that water tube boilers can go to higher pressures. Firetube boilers are generally limited to 300 psi or less. The second reason is that
Apr 23, 2012· Water Boilers Main Features Advantages Major advantages of water tube boiler systems include: These boiler systems contain very small quantity of water hence; their response is fairly quick towards variations in load and heat supply. The small diameter tubes and steam drum mean that much higher steam pressures can be tolerated, and up to 160…
Apr 23, 2018· The water-tube boiler has some special advantage that the fire tube boiler doesn’t have. Before we start let’s know about the working principle of a water tube boiler and it will help you to understand its advantage and disadvantages clearly. Water Tube Boiler Working Principle: First of all Water Tube Boiler and Fire Tube Boiler are
Apr 14, 2020· Advantages and disadvantages compare to what? Let’s assume it is compared with fire tube and smoke boilers: Water Tube Boiler: Advantages• * Water circulates in the tubes and fuel is burned inside the furnace. * Low water content * Quicker steam r
Advantages of fire tube boilers: - More residual heat in the water to allow for load swings - Simpler control systems due to larger volumes of water in shell - Water quality doesn't change as
Advantages of fire tube boiler: 1. The water is supplied in shell and outside tubes while hot gas is supplied inside tubes so the water volume can not be shaken easily when the fire tube boiler is running. 2. Fire tube boiler is so easy to use, operate, clean and maintain 3. Fire tube boiler can be used in small scale industries. 4. Fire tube
Advantages and Disadvantages of Water Tube Boilers over Fire Tube Boilers: Advantages: 1. Steam can be raised more quickly: In water tube boilers, the ratio of water content to the steam capacity is comparatively less than the fire tube boiler. Hence water tube boilers can quickly generate steam at the required pressure than the fire tube boiler. 2. Steam at higher pressures can be produced
