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.
There are two sides to every firetube boiler, the water side and the fire side. Both require bi-annual inspection. Appropriate maintenance must be perform in order to keep your equipment running at peak efficiency. The fireside of your boiler will include all refractories, furnace, tubes, and tube sheets. First open the boiler up:
inside the boiler to allow for a visual inspection of the water side of boiler and aid in the cleanout of mud and sludge from the waterside of the boiler. Manholes allow for the inspector to physically enter the boiler and are for the inspection of the steam drums and mud …
Inspecting the Fireside of a Boiler, Part 2 | OpenSesame Describe how to inspect a bottom ash hopper in a large watertube boiler. Describe how to inspect the fireside of an economizer in a large watertube boiler.describes how to inspect fire side and water tube boiler – …
Regular waterside inspection of boiler tubes provides the information required to determine the effectiveness of water treatment, maintenance procedures, diagnoses of boiler operating troubles, and in general an overall condition of the boiler. Tube failures generally occur in the outer half of the tube nest from external corrosion just above
File Size: 224KB The total heating surface of a boiler includes all parts of the boiler which are exposed on one side of the gases of combustion and on the other side to the water and steam being heated The heating surface incudes: generating surface, generating tubes, screen tubes, waterwall tubes, support tubes, superheater surface, and economizer surface
Third Party Inspection for Fire Tube Boiler - Marking. Identification marks is checked by third party inspector and information stamped using low stress type stamps on pressure parts. Third Party Inspection for Fire Tube Boiler - Name Plate Checking. The third party inspector checks the Fire tube boiler name plate and makes sure: Material is
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
Inspection and Test Plan for Water Tube Boiler You may also want to review boiler inspection and water tube boiler inspection procedure /instruction articles. The ASME Code Section I requirements are normally applied for the inspection and test plan in a manufacturing shop.
In water-tube boilers, the fluid with the higher density flows through the tubes and the fluid of lower density flows through a larger diameter external to the tubes (combustion chamber), ultimately resulting in water-tube boilers having higher overall heat transfer coefficient when compared to a fire-tube condensing boiler of the same size and
Boiler: A Boiler is a closed vessel in which steams are generated (Water to steam) with the help of coal-burning or other fuel substances.. Basically, There are two types of Boiler. Fire Tube Boiler; Water Tube Boiler; Fire Tube Boiler: The fire-tube boiler is the boiler in which fire (hot flue gases) is inside the tube and water is surrounded by them.. Some example of Fire Tube Boiler are:
