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.
May 10, 2017· Design Variations i) D-type boiler the most common type of small- to medium- sized boilers used in both stationary and marine applications ii) Cross Drum Water Tube Boiler In Cross Drum Boiler the steam drum is placed at cross ways to the heat source 13 14.
The uppermost or highest positioned drum is referred to as the STEAM DRUM, while the middle drum is referred to as the WATER DRUM, and the lowest, the MUD DRUM. Tube banks connect the drums. The tubes are bent at the ends to enter the drums radially. Water enters the top rear drum, passes through the tubes to the bottom drum, and then moves up

Looking for cross drum boiler? Find out information about cross drum boiler. A sectional header or box header type of boiler in which the axis of the horizontal drum is perpendicular to the axis of the main bank of tubes Explanation of cross drum boiler
A cross-tube boiler was the most common form of small vertical boiler.They were widely used, in the age of steam, as a small donkey boiler, for the independent power of winches, steam cranes etc.. The boiler has the advantage of simple robust construction, in particular requiring little regular maintenance.
Straight Tube Boilers. The STRAIGHT-TUBE class of water-tube boilers includes three types: 1. Sectional-header cross drum 2. Box-header cross drum 3. Box-header longitudinal drum. In the SECTIONAL-HEADER CROSS DRUM boiler with vertical headers, the headers are steel boxes into which the tubes are rolled.
A cross drum straight tube boiler a) could not have higher capacity than a longitudinal drum unit b) was usually only of single pass design c) could have more inclined tubes than a longitudinal drum unit d) is a very popular design in today's plants e) was internally fired
ternals and baffles to control water levels, reduce surging, and to reduce the quantity of moisture leaving the water level before it enters the final dryer unit. Figure 1-2 shows a cross section of typical drum internals. The boiler is constructed in accordance with the ASME Power Boiler Code, and all applicable
What is a water tube boiler? Water tube boilers were developed for a variety of reasons, including the need for higher steam pressures, higher steam generation rate, superheated steam. these types of boilers have quicker response to load changes. We briefly discuss about Water tube …
