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.
User rating: 4.2/5 Mar 12, 2013· Types of Marine Boilers and Difference Between Water Tube and Smoke Tube Boilers Posted on March 12, 2013 November 25, 2019 Author Mark Eriscson Comment(0) This article is to discuss about the various types of marine boilers that are being used or once used to drive the ships or to generate the steam.
Marine Boilers, Third Edition provides practical information about boilers and other relevant equipment used at sea on steam and motor vessels. The coverage of the book includes auxiliary boilers, water tube boilers, and boiler mountings. The text also covers stresses in boiler shells; combustion of fuel in boilers; and boiler operation.
Marine engines and boilers. By John Riley 1998 (c) NSW Heritage Office (Models of engines and boilers by John Riley. Photography, unless otherwise indicated,David Nutley) The development of engine powered vessels is credited as early as 1783. However, the first practical steam vessel was constructed in Britain in 1802.

For marine boilers the corrugated flue has been the type most extensively used. Early experiments carried out to test the relative strengths of the corrugated flue and of the plain furnace tube showed that the improved form was able to withstand an external hydraulic pressure of 1,020 lb a square inch compared with 225 lb on the unstiffened flue.
Marine boilers are of two types namely the water tube boiler and the fire tube boiler. The water tube type boiler is used for high-pressure, high-temperature, high-capacity applications. The Main boiler design depends on its application, ie. for motor ships, a small fire tube boiler would be satisfactory.
The main reason for the adoption of this design of boilers is to allow use of modern high efficiency watertube boilers without fear of damage through contamination by cargo or fuel oils. The basic design consists of a D-Type boiler design upon which is mounted a Steam/Steam generator drum.
The Scotch marine boiler achieved near-universal use throughout the heyday of steam propulsion, particularly for the most highly developed piston engines such as the triple-expansion compounds. It lasted from the end of the low-pressure haystack boilers in the mid-19th century through to the early 20th century and the advent of steam turbines
Book Edition: 4 Oct 13, 2015· What is the meaning of marine boilers ? Boiler is a pressure vessel used on ships in which the water is heated to evaporate and generate the steam and the unit is so arranged that the generated steam accumulated in it. The two main types are water tube and fire tube. What is the boiler mounting ?
The Pennsylvania was a side wheeler steamboat which suffered a boiler explosion in the Mississippi River and sank at Ship Island near Memphis, Tennessee, on June 13, 1858. Of the 450 passengers on board more than 250 died, including Henry Clemens, the younger brother of the author Mark Twain.. SS Ada Hancock, a small steamboat used to transfer passengers and cargo to and from the large coastal
