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.
Tube leakage is the serious problem in Boiler, it could cause heavy damage to Boiler. Hence it is very essential to avoid this problem as possible as by conducting hydraulic test before Boiler start up. I am below giving what action to be taken if
As a result, fire tube boilers typically use much more energy than is actually needed to get the job done, resulting in waste heat and higher fuel/water costs. Second, there’s the issue of space. Conventional industrial boilers take up a lot of room by design, requiring a separate boiler room to accommodate them.
What is a water tube boiler? Water tube boilers were developed for a variety of reasons, including the need for higher steam pressures, higher steam generation rate, superheated steam. these types of boilers have quicker response to load changes. We briefly discuss about Water tube …
Shell boilers may be defined as those boilers in which the heat transfer surfaces are all contained within a steel shell. Shell boilers may also be referred to as ‘fire tube’ or ‘smoke tube’ boilers because the products of combustion pass through the boiler tubes, which in …
Author: wareboilers Aug 04, 2018· Down comers are the Pipelines which are connected between Boiler Steam drum And water panel headers. Water coming out from the Boiler Feed pumps goes to the feed water heaters first there will be increase in the water temperature. Again it enters
Author: Tim Seberger Mar 04, 2020· A water tube boiler is such kind of boiler where the water is heated inside tubes and the hot gasses surround them. This is the basic definition of water tube boiler. Actually this boiler is just opposite of fire tube boiler where hot gasses are passed through tubes which are surrounded by water.. Advantages of Water Tube Boiler. There are many advantages of water tube boiler due to which
File Size: 322KB Soluble-salt deposits may form at a superheater tube inlet as a result of excessive entrainment of boiler water solids with the steam. This can result in restricted flow. However, overheating and direct oxidation failures may occur in areas distinctly removed from the blockage, such as the bottom loops or the hottest areas of the superheater tubes.
The Johnston boiler is a steam or hot water packaged firetube boiler, ranging in size from 50 to 2,500 horsepower, 15# to 350# design pressure, 3 or 4 pass, of welded steel construction with submerged rear combustion chamber. The package consists of a pressure vessel, base frame,
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
