Title: Dryer drum coater having recirculation chamber for voc/nox reduction
Inventor: SWANSON MALCOLM L
IPC: F26B11/02
Filed: 1995-03-06
Abstract: A dryer drum coater (110, 310) has an internal recirculation cylinder (200, 400) for promoting the recirculation of combustion products so as to entrain and incinerate blue smoke formed when heated and dried virgin aggregate is mixed with other asphaltic products such as RAP and/or liquid asphalt in the dryer drum coater. The recirculation cylinder (200, 400) acts to extend and strengthen natural eddy currents formed during operation of the coater such that combustion product recirculation which would normally extend only in the end area of the flame extends far enough toward the base of the flame to entrain the blue smoke and to draw the blue smoke into the base area of the flame. The cylinder may comprise a refractory lined stainless steel shell (204) or may be formed from tee flights (402) of the type used in the combustion zones of dryer drum coaters.
Patent CA-2186162-A1 (CA)
Inventor: NILSSON OVE
IPC: H01M50/50
Filed: 1995-03-22
Abstract: Accumulateur au plomb dont la totalité des surfaces de toutes les électrodes sont soumises à une pression élevée tandis que leur circomférence est maintenue inchangée grâce au support assuré par des parois d'éléments mécaniquement rigides, de sorte que ces électrodes ne peuvent s'accroître qu'en épaisseur sous l'effet d'une contrainte élastique puissante au cours de la décharge, pour revenir à leur volume initial au cours de la charge. La pression exercée est de l'ordre de 0,49-10?5¿9,81-10?5¿ Pa (0,5-10 kp/cm?2¿), elle peut être obtenu par des séparateurs ou des ressorts appliqués contre les parois externes du boîtier d'éléments, et peut être modifiée pour une capacité plus petite ou plus grande. La configuration tubulaire de l'accumulateur prévient toute perte de matière par épaississement et assure une longue durée de service, également du fait qu'un conducteur au plomb entièrement corrodé peut, sous forte pression, fonctionner comme conducteur de courant. Les enveloppes externes rigides autorisent une pression élevée des liquides et, en conséquence, une solubilité et une recombinaison élevées de l'oxygène des éléments étanches.
