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.
May 23, 2016· power plant boiler steam drum internals Boiler steam drum is very important part of any power plant .it is also called “heart of boiler “Because of its importance in steam generation. Boiler steam drum acts as reservoir which provides necessary head for circulation of water through evaporation zone.
To avoid such primary-secondary leaks, steam generator tubes are periodically inspected by eddy-current testing, and individual tubes can be plugged to remove them from operation. As with many nuclear components, mechanical engineers determine the inspection frequency using the known rates of corrosion and crack propagation in the material.
As an aside, all hot forming and shaping employed to make boiler tubes and piping is done in the austenite temperature range of 1650 o F to 2000 o F. With the continued cooling, the face-cantered-cubic austenite begins to transform to body-centered-cubic ferrite at a temperature of around 1600 o F, and again, the exact temperature depends on
Jan 09, 2017· Teknologi boiler supercritical (SC) dan ultra-supercritical (USC) telah digunakan pada beberapa dekade terakhir. Teknologi ini memiliki beberapa keunggulan dibanding tipe boiler subcritical. Keunggulannya antara lain: Plant efficiency yang lebih tinggi, sehingga mengurangi biaya operasi Emisi CO2 yang lebih rendah dari boiler subcritical.
Why is the Cochran boiler shell made with a sphericalSep 30, 2018What material is used for covering the surface of a boilerMay 14, 2018Which material is used for a superheater in a boiler?Mar 03, 2018Which material is used to make an industrial boiler? See more results These standards specify the classification, size, shape, weight and allowable deviation, technical requirements, inspection and test, packaging, marking and quality certificate of seamless steel tubes for boiler. Boiler Pipe Size. Boiler pipe size range complied with the different ASTM standard required. Like ASTM A106 or ASTM 179, 192 etc.
Drawing upon a full century of experience and expertise, Boiler Tube Company of America (BTA) manufactures replacement pressure boiler components and related auxiliary industrial boiler parts for all sizes and styles of boilers, regardless of original OEM.
File Size: 489KB Boiler tubes for today and tomorrow Sandvik manufactures and delivers a broad range of austenitic seamless stainless steel tubes for today’s boilers. High steel quality and close production control assure consistent tube quality. Sandvik is constantly improving tube material and production methods to comply
Tube failures are a cause of concern in boiler outage, contaminating boiler feed water due to condenser leakage leads to a large amount of damage. Condensers using brackish water for cooling in high pressure boilers will have to be maintained well to avoid any leakage of condenser tubes. Any leakage of condenser cooling water to the condensate leads to low pH levels in boiler water, which can
Boiler tubes of a coal fired plant faced harsh environment all the way from inside steam to outside flue gases. Tubes are exposed to temperature in the range of 540–1000 °C, varying along length of tubes i.e. from base toward elevation. According to service condition, outside of …
Jan 31, 2017· If boiler feed pump is not started and no water goes into the boiler due to starvation over heating of tubes take place and it may be deformed, ruptured or explosion may take place . So in case of boiler feed pump are not available, boiler is to be stopped immediately.suction line of the boiler feed pump is connected to deaerator storage tank
Thermal Power Station process flowchart and diagram. The fuel is transported from mines via trains to the fuel storage facility in a power plant. The fuel transported to the plant is generally bigger in particle size and before it is fed to the boiler furnace it is broken down into smaller pieces using crushers.The fuel is then fed to the boiler generating a large amount of combustion heat.
