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.
Additionally, the weight of the water tube boiler is much less compared to other types of boiler of equivalent size due to a reduced volume of water in the boiler. D type watertube boiler design. D type watertube boilers are designed with a large steam drum at the top, vertically connected to a smaller water drum (or "mud drum") at the bottom
A high pressure watertube boiler (also spelled water-tube and water tube) is a type of boiler in which water circulates in tubes heated externally by the fire. Fuel is burned inside the furnace, creating hot gas which heats water in the steam-generating tubes.In smaller boilers, additional generating tubes are separate in the furnace, while larger utility boilers rely on the water-filled tubes
Water tube boilers are the most widely used boilers. These type has replaced many boilers, including the fire tube type, mainly because of the following reasons : The weight of the water tube boiler is much less than any type of boiler of equivalent size. Steam raising and steam generation process is much faster
There are several different non-condensing boiler designs for commercial operations: Water tube: where tubes will contain water and steam as the combustible fuel flows around the tube. The tubes are connected to different drums to create the furnace and convection areas. …
1998-6-24 · EFFICIENCY OF ENERGY CONVERSION Steam boiler Chemical energy Thermal energy knowledge of the device's function (as shown in Table 4-1 and illustrated in Figures 4 …
May 04, 2017· Water tube boiler working and function 1. Water Tube Boilers In this type of boiler water passes through the tubes while the gases remain in the shell side, passing over the tube surfaces • Used for high steam demand and pressure requirements • Capacity range of …
Condensing boilers are water heaters fueled by gas or oil. They achieve high efficiency (typically greater than 90% on the higher heating value) by condensing water vapour in the exhaust gases and so recovering its latent heat of vaporisation, which would otherwise have been wasted.This condensed vapour leaves the system in liquid form, via a drain.
Water Tube Boiler Parts And Their Functions 2018-02-27 13:38:34. There are many pressure parts and non pressure parts in a water tube boiler, we list the main components of the water tube boiler and their functions. Steam drum. Steam drum is a collection vessel for steam & water. Here water & steam is separated. It has steam separators.
Water tube boiler parts and their functions. There are many pressure parts and non pressure parts in a water tube boiler we only discuss main water tube boiler parts and function. Steam drum. Steam drum is a collection vessel for steam & water. Here water & steam is separated. It has steam separators.
Water-tube boiler: 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.
Water passes through boiler tubes while the combustion gases remain on the shell side, passing over the tube surfaces. II Applications Water tube boilers are most commonly used where high steam pressures are required and can exceed 3,000 psig.
