Title: Air supply nozzles for floor of fluidised bed reactors - where nozzles are syphon-shaped with closable branch pipes for ease of cleaning
Inventor: REIDICK HEINZ
IPC: F23C10/18
Filed: 1992-09-12
Granted: 1994-01-05
Abstract: An air-supply floor (3) for a fluidised bed reactor (2) has a refractory lining (4) and syphon-shaped air nozzles (5) with vertical supply (6) and delivery (7) pipes. The syphon-shaped sections prevent ash etc. falling back into the air supply system. The upper ends (12) of the delivery pipes are at the same level as the surface of the refractory lining. The novel feature is that an extension of the delivery pipe (7), in the form of a branch pipe (9), is inclined at an angle of between 0 and 20 deg. to the vertical axis of the delivery pipe (7) in the direction of the supply pipe (6). This pipe branch passes through the air-supply floor (3) into the wind-box (8) and is fitted with a removable cap (10). USE/ADVANTAGE - In fluidised-bed reactors. The branch pipes allow the syphon pipes to be cleaned and blockages removed, a compressed air supply may be attached to them for rapid cleaning of the nozzles, and maintenance and down-time are reduced and the availability of the reactor is therefore increased.

Title: Method for producing the action of an air shockwave and device therefor
Inventor: KOEHLER KURT A DIPL PHYS DR
IPC: G01M7/08
Filed: 1993-07-17
Granted: 1994-10-27
Abstract: The invention relates to the determination of the synergetic destructive action of an air shockwave and thermal flashwave. In order, on the one hand, simply to reproduce an air shockwave and, on the other hand, to let a thermal flashwave occur at an arbitrary time, provision is made     - to clamp a flat sample (10) in a clamping device, - to depressurise a vacuum chamber (30) provided with a diaphragm (40), - to destroy the diaphragm (40) so that the negative pressure acts on the surface of the sample (10) facing a previously gas-tight intermediate chamber (20) which is at ambient pressure, via this intermediate chamber, as a result of which the action of an air pressure wave is produced on the surface of the sample (10) remote from the intermediate chamber, - independently of the time of destruction of the diaphragm (40) exposing the freely accessible surface of the sample (10) which is remote from the intermediate chamber to a thermal flashwave.   <IMAGE>
