Fluidstrip Fluidised Bed Furnaces

Principle

The "Fluidstrip" fluidised bed furnace uses a combustible mixture of air and gas to fluidise a bed of sand.  The air/gas mixture is ignited at the surface of the bed by a pilot flame.  The bed heats up to a maximum of 600^oC through "internal combustion".

Parts are then lowered into the "Fluidstrip" in special steel baskets.  The plastic or paint coated parts undergo pyrolisis once in the bed. (The paint or plastic decomposes with heat).  The waste gases are burned when they reach the surface.

Fluidstrip Offers More Advantages

Compared to other available fluidised bed sand furnaces, Fluidstrip offers advantages including:

• Safe mixing of gas and air to avoid potential explosions.

• The retort (furnace chamber) is corrugated and supported from the top, giving a longer retort life and satisfactory seal.

• Special distribution design to provide good mixing of gas and air in the bed

• Efficient uniform transform of heat, reducing the risk of distortion.

• Progressive burn-off within a controlled environment

• No preparation or removal of large concentrations of resins before the process

• Substantial saving in process time

• Substantial saving in after-stripping and cleaning time

• Complete pollution correction

Fluidstrip Standard Program

The Fluidstrip units are available in standard sizes from 300mm to 2000mm in diameter and from 3000mm long x 1000mm wide to depths of 1500mm.  Tailor made furnaces can also be provided.

Applications

For many years there has been a demand throughout the world for a fast efficient and cost effective method of cleaning and removing paint, resins, epoxies and grease from paint jigs, electric motors, coils, wires and automotive components.

Vinyl, teflon, rubber, urethanes and neoprene coatings can also be thermally destroyed.  If however, the exhaust gases contain halogens, such as chlorine, special additions are used including scrubbers, packing and dry lime towers, to ensure that the resultant air discharge is satisfactory.
