Patent DE-4343332-A1 (DE)
Title: Convective cooling device for sealed combustion chamber
Inventor: SCHULTE-WERNING BURKHARD DR
IPC: F23R3/06
Filed: 1993-12-20
Abstract: The cooling device consists of external (4) and internal (6) walls of the combustion chamber, with a cooling passage between them. The external load-bearing wall is fixed to the relatively thin internal wall (6) all along the cooling passage, forming several separate cooling channels (5). The connection between the internal and external walls may be in the form of longitudinal ribs (7) formed as projections from the internal wall, running along the cooling passage and forming channels sealed at external-wall side by contact between the ribs and the external wall. The shape, spacing and dia. of the channels and the shape of the ribs can be made to the appropriate dimensions for optimum efficiency.

Title: Sewage sludge or slurry dryer
IPC: C02F11/13
Filed: 1994-01-20
Abstract: Moist size-reduced sludge is pre-dried in an air lift process, entrained into the hot air stream in a finely divided state, and conveyed to final drying in a fluidised bed. A proportion of the finished, dry sludge is recycled and mixed with the feed; the mixture being reduced in size.

Title: Appts for heating surface of conductor plates to be soldered
Inventor: ULLRICH RUDOLF
IPC: B23K1/012
Filed: 1994-05-13
Abstract: The apparatus for producing a non-laminar gas flow in a heating plant consist of several reflectors (9) arranged in parallel above the conveyor carrying the parts to be treated. The gas passes between the reflectors into the area between the reflectors and the conveyor and produces a whirling effect. From here the gas passes to the end of the reflectors and is recirculated. The reflectors are U-shaped with the open side facing the parts. In the absence of a part to be treated, a lamella plate (33) is put on the conveyor to cause a whirling effect. A turbine shaped wheel (13) is used to circulate the gas through a channel (30) down onto the parts. From there the gas passes via the sides of the chamber (between 16 and 18) back to the wheel (13) after passing a heater (14) controlled by sensor (15). An IR radiating device (41) may be located in one of the reflectors to heat the parts. The drive shaft of the wheel is provided with a vibration damping unit (28) to prevent vibrations passing from the motor into the wheel. Gas essentially free from impurities is passed via channel (26) onto the bearing of the drive shaft and joins other treatment gas flowing between partitions (16, 18). A cooling unit below the conveyor consists of gas circulating in channel (34) through ventilator (32) and evaporator (33) which constantly withdraws heat from the gas. As the cold gas flows it cools panel (36) and reaction gas with impurities flowing out of nozzles (31) contacts the panel and deposits its impurities (43) by condensation.
