Long Term Chemical Leaching from Incinerator Residue

This paper presents another type of bin which has successfully been used on material hard to dis­ charge from a storage bin, including industrial waste. I would like to point out that the Eastman Kodak Co. has handled material as low in density as lib/cu. ft. I would suggest that a paper follow this one giving more details. The information given in this paper whets the appetite for more information. What are some actual experiences with existing installations? Have any problems occurred with: 1. Pluggage or bridging? 2. Jamming screws? 3. Bearing problems? 4. Fire or dust explosions in bins? 5. Drive problems? 6. FreeZing to walls? Why is thrust greater with steeper hoppers? What is width limit? length limit? What is exper­ ience starting scr�ws after material has set in the bin several days? Are any special details considered in wall or hopper construction? Have you developed any information on effect of height of material on density or side wall pres­ sures? What specifications are used for drives? I would recommend enclosing drive units sufficiently to provide protection for motors and maintenance in inclement weather. What specifications for materials in the bin do you require? A future paper might consider how C. DONALD FISHER
