membrane wall boiler - Bing 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.
Technical advantages 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.
Easy operation and maintenance
Fully automatically operating, with automatically adjustment and protection of burning, water level, temperature and steam pressure.
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.
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.
Membrane or Fin Tube Water Wall Membrane or fin tube water wall is now best design and construction because this type can give more protection in the insulation and give highest efficiency and heat transfer surface (see figure 4). Reference: Book – Central …

Solid Fuel Memberane Wall (SFMW) Boiler . It is 2-drums designed with 3-horizontal passes. The first pass comprises a well defined furnace and a radiation room where the segregation of coarse fly ash takes place. The second and third pass contain the evaporator bank and the superheater that protects from overheating.
Monowall or membrane wall ; Tangent Tube. In tangent tube arrangements, small diameter tubes are closely pitched together to form an arrangement backed by three layers, namely – refractory, insulation and boiler casing. The problem with this arrangement is that, in case of tube failure the welded repairs become a bit difficult to carry out.
Besides, the angle between the lower furnace and the ash hopper gives the membrane wall a place to expand, where there is always exist an extremely high strain and stress zone on it. 3. The most vulnerable area on the membrane walls in an AF boiler is the overlap area of high stress and high temperature on the front wall.
(1) the protective effect of membrane water cooling wall on the furnace wall is the most complete, so the furnace wall only needs insulation materials, rather than refractory materials, so that the thickness and weight of the furnace wall are greatly reduced, simplify the structure of the furnace wall, reduce the total weight of the boiler.
Membrane Wall Laser Welding. Membrane walls enclose the combustion chambers and boiler passes in steam generators. The tube–web–tube welds necessary for the production of these membrane walls are produced conventionally by means of submerged-arc welding.
