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.
Mar 12, 2013· In this post I have discussed about how classification of marine boilers are done. In the last what are the uses of steam on board ship has also been discussed in this article and they should be known to the cadets. The main idea is to make to study basics of boilers in order to have an idea about the boilers that are used on ship. If you have
Today’s steam generating systems owe their dependability and safety to more than 125 years of experience in the design, fabrication and operation of water tube boilers. Boiler classification can be based on many factors like usage, fuel fired, fuel firing system, type of arrangement etc. The commonly known types are pulverized coal fired boilers, fluidized bed boilers, super critical boilers
Steam Boiler Classification. Steam boilers are built in the world from 200 BC until today, many developments have taken place that allow us to classify steam boiler in different ways. Hence steam boiler may be classified based on the following characteristics: 1.
Water-tube boilers are primarily used in higher pressure steam applications and are used extensively for comfort heating applications. They typically range in size from 500,000 to more than 20,000,000 BTU input. Cast iron sectional boilers are another type of boiler commonly used in …
Selection of steam boiler depends upon the following factors: Power required and working pressure. The geographical position of the powerhouse. Fuel and water are available. Probable permanency of the station. The probable load factor. Classification of Boilers. The steam boilers classified as follows:
water or steam, to produce a source for either heat or power. A central heating plant may have one or more boilers that use gas, oil, or coal as fuel. The steam generated is used to heat buildings, provide hot water, and provide steam for cleaning, sterilizing, cooking, and laundering operations. Small package boilers also provide steam and hot
Sep 13, 2018· Boilers are a tool for creating steam. The existence of boilers has been important since its development in the range of the 18th and 19th centuries. Boilers also took an important role in the era of the Industrial Revolution and encouraged various other important discoveries. In subsequent developments many studies have succeeded in bringing out … Continue reading "Classification of …
The steam is essentially supplied at constant pressure by maintaining the rate of steam generation and supply of feed water. This way the water level inside the vessel is maintained constant. Classification of Steam Boiler: A boiler may be classified as follows: (i) Fire tube and water tube boilers
Jul 02, 2016· (ii) Externally fired boiler: In externally fired steam boilers, the furnace is arranged underneath in a brick work setting. Water tube steam boilers are always externally fired.. According to the axis of the shell (i) Vertical boilers: In vertical steam boilers, the axis of the shell is vertical. Simple vertical boiler and Cochran boiler are vertical boilers.
