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.
Industrial plants rely on steam for heating and other processes, and boilers are commonly used to provide this steam. This unit examines the basic principles of boiler operation and the basic concepts of heat transfer. The major types of boilers used in industrial facilities are also described.
Boiler Control for Fossil-Fired Utility Boilers General Control Philosophy Honeywell's control philosophy is to provide a complete control system designed to operate a unit safely and efficiently over the unit's entire operating range. Honeywell can provide controls for the entire plant from the coal pile, to the burner safety system, to
Dec 21, 2007· There is a company that basically wrote the book on boilers its the Kewanee Boiler Co. If you want to do a little reasearch you can find them all over the net.. A boiler works like this . 1. you must have a heat source..gas , coal , wood or even electricity. 2. You must have a presuurized system that has a controlled steam output . 3.
File Size: 271KB A careful study of this chapter can help you acquire useful knowledge of steam generation, types of boilers pertinent to Seabee operations, and various fittings commonly found on boilers. The primary objective of this chapter is to lay the foundation for you to develop skill …
Pulverized fuel boiler – Most of the coal fired power station and industrial water tube boilers use pulverized coal. This technology is well developed, and accounts for well over 90 % of coal fired capacity. The coal is ground to a fine powder, so that less than 2 % is +300 microns (?m) and 70-75 % is below 75 microns for a bituminous coal.
Dec 11, 2019· A comprehensive database of more than 14 boiler quizzes online, test your knowledge with boiler quiz questions. Our online boiler trivia quizzes can be adapted to suit your requirements for taking some of the top boiler quizzes.
Nov 19, 2013· Water-Tube Boilers. A water-tube design is the exact opposite of a fire tube. Here, the water is inside the tubes and the combustion gases pass around the outside of the tubes. Water-tube boilers may vary in design; however, their basic principles of operation are the same. This type of boiler consists of two drums, a series of water tubes, a
File Size: 1MB The basic design of a boiler can be used in different applications. Other than being used for locomotives, it can be used in combustion engines and power plants as well. It is also known as the steam generator of a fossil fuel power plant. The boiler is used to help the combustion of coal, natural gas, or oil.
