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.
PACKAGED WATERTUBE BOILERS The bent tube watertube boiler is also produced as a packaged unit. That is, the boiler, burner, draft fan, feed pump, controls, and other accessories are all included as a unit and supplied by the boiler manufacturer. These units have water-cooled furnaces, and the air for combustion is supplied
Mar 04, 2020· There are different components present in feed water and steam circuit of boiler and we should know some essential components of these circuit and these are Economizer, boiler drums, water tubes, and super heater.. Economizer. Economizer is a heat exchanger which takes heat from the flue gas, and increases the temperature of feed water coming from feed water common header to about …
Nov 19, 2013· Boiler Basics A boiler is used to heat water that is circulated through a closed loop piping system for general facility and service water heating. Low-temperature systems generally operate below 200 degrees Fahrenheit. Medium-temperature systems generally operate between 200 and 250 degrees Fahrenheit. Most facility boiler systems are fired using a combustible gas, fuel oil, or electricity
Sep 26, 2016· For industrial companies using a boiler for its facility, some type of boiler feed water treatment system is usually necessary to ensure an efficient process and quality steam generation. The most appropriate boiler feed water treatment system will help the facility avoid costly plant downtime, expensive maintenance fees, and boiler failure as a result of scaling, corrosion, and fouling of the
File Size: 881KB When the boiler is shut down, inspect for scale deposits, accumulation of sediment or boiler compounds on the water-side surfaces. Stack flue gas temperatures should be no more than 150° greater than the steam or water temperature. Clean and scrape fire-side tubes to remove soot and scale if the desired temperature split is exceeded.
Advantages of Water Tube Boiler1. Larger heating surface can be achieved by using more numbers of water tubes. 2. Due to convectional flow, movement of water is much faster thanWorking Principle of Water Tube BoilerMore and more steam is produced the pressure of the closed system increases which obstructs this convectional flow of water and hence rate productiTypes of Water Tube Boiler1. Horizontal Straight Tube Boiler. 2. Bent Tube Boiler. 3. Cyclone Fired Boiler. 1. Longitudinal Drum Boiler 2. Cross Drum Boiler. 1. Two Drum BenCross Drum Water Tube Boiler1. The feed water is fed to the cross drum through feed water inlet. 2. Then this water comes down through the down-comer pipe and enters into incl Steam Systems 4 Figure 1.

File Size: 258KB Nov 14, 2016· Boiler's are just over sized tea kettles.. transfer heat into the water to create steam. To do that efficiently and to the scale that these boilers have to work at, they become much more complex
Water passes through boiler tubes while the combustion gases remain on the shell side, passing over the tube surfaces. II Applications Water tube boilers are most commonly used where high steam pressures are required and can exceed 3,000 psig. Water tube boilers can generate saturated or superheated steam, which is useful for applications such
2. BOILERS Bureau of Energy Efficiency 27 Syllabus Boilers: Types, Combustion in boilers, Performances evaluation, Analysis of losses, Feed water treatment, Blow down, Energy conservation opportunities. 2.1 Introduction A boiler is an enclosed vessel that provides a means for combustion heat to be transferred into water until it becomes heated water or steam.
A superheater steam attemperation is when we control the temp. by combining either pure water or saturated steam with the superheated steam to maintain a constant temp. 26. Explain why the outlet temperature tends to rise with load in convection type superheater and decreases with a load in a radiant type superheater.
