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.
V. Ganapathy is a consultant on steam generators and waste heat boilers based in Chennai, India. He has over 42 years of experience in the engineering of steam generators and waste heat boilers with emphasis on thermal design, performance, and heat transfer aspects. He also develops custom software on boiler design and performance.
This article describes the use of a general-purpose computational-fluid-dynamics code for improving and optimizing waste-heat boilers in the Outokumpu flash smelting The modified boiler, with its unique design, has been in use at Outokumpu's Harjavalta copper smelter since June 1995 with excellent performance. waste-heat boiler and cleaned
Selection of waste heat boiler. The quantum of waste heat available and the temperature at which it is available more or less decide the systems to be used for cogeneration. Apart from the system choice, there are also several choices regarding how to fit the system. These aspects are dealt with in the following chapters.
Abstract. This lecture describes the principal types of unfired modern steam raiser, concentrating on land-based units in service in the power and process chemical industries; the methods used for the thermal design of the various types; and the common problems encountered during the operation of steam raising equipment.
Waste heat is heat that is produced by a machine, or other process that uses energy, as a byproduct of doing work.All such processes give off some waste heat as a fundamental result of the laws of thermodynamics.Waste heat has lower utility (or in thermodynamics lexicon a lower exergy or higher entropy) than the original energy source.Sources of waste heat include all manner of human
A brick like form of insulation that is used to reflect heat back into the firebox and protect the structural steel in the boiler. What all is located in the firebox of a boiler? Radiant tubes and riser tubes both contain boiler feedwater that is heated by radiant heat from the burners and boiled to form steam that is returned to the steam drum.
Incorporates Worked-Out Real-World Problems Steam Generators and Waste Heat Boilers: For Process and Plant Engineers focuses on the thermal design and performance aspects of steam generators
Hello, thanks so much for the information i really appreciate it. for the waste heat boiler, the flowrate of the gas is 12.31kg/s and it enters the boiler at a pressure of 25bar. the flowrate of the water is 10.36kg/s. the composition of the gas is as follows in mole fractions:
Difference Between Waste Heat Boiler And Other Boilers 2018-01-09 13:15:49. Although the waste heat boiler is also known as the boiler, but it is different from other boilers. 1. The structure is different. Conventional boilers are usually made up of furnace, boiler drum, burner, superheater, economizer, air preheater, frame and furnace wall, etc.
Waste Exhaust Heat Boilers. Approximately 25% of the usable energy of the fuel gas is released in the exhaust of the gas engine. This can be captured for cogeneration in a combined heat and power plant. This heat exits the engine at ~450 o C as ‘high grade heat’, contrasting to ‘low-grade heat’ available from the generator cooling circuits. This high temperature and flow makes it well
