Title: Screw feeder type powder cooler
Inventor: ASAKAWA TAKAYOSHI
IPC: B65G33/26
Filed: 1993-07-14
Abstract: PURPOSE:To prevent backflow of combustion gas from a rearflow device by providing plate-shaped screw vanes which are mounted on a powder inlet side of a lower part of a hollow screw shaft and a powder outlet side of an upper part, and a hollow screw vane which is mounted on a middle part of the hollow screw shaft in succession to each of the plate-shaped vanes. CONSTITUTION:Ash thrown in through a powder throwing inlet is moved in a screw feeder by a plate-shaped screw vane 13 at a lower part and reaches an area in which a hollow screw vane 14 is mounted. Then, only ash at a bottom part of a cylindrical external shell's internal wall 16 is pushed up by the hollow screw vane 14, overflows over a hollow part of the hollow screw vane 14, slides down in the cylindrical external shell's internal wall 16, forms a level 15 of powder and fills the lower part of the screw feeder with compressed ash. By this, it becomes possible to prevent back-flow of fluidized air from a screw feeder rearflow device.

Title: Zeolite granules
Inventor: TERASE KUNIHIKO
IPC: B01D53/04
Filed: 1990-07-03
Abstract: PURPOSE:To obtain such a zeolite from which separated gas such as high concn. nitrogen and oxygen can be obtained as much as possible in a unit time and unit weight, by specifying the calcium substitution rate and specific surface area of zeolite. CONSTITUTION:This zeolite granulare body is obtained by substituting Ca ions for >=95% of Na ions in sodium-A zeolite, and has >=8m<2>/g specific surface area. The zeolite granules thus obtd. have good selectivity for gas and a large gas adsorption/ desorption rate. If the Ca substitution rate in this granular body is <95%, adsorption amt. of nitrogen decreases. Though the larger specific surface area gives the larger adsorption amt. of nitrogen, strength of the granular body may decrease when the specific surface area exceeds 15m<2>/g.
