Effective Temperature Control for Cement Kiln Off Gases
The main gas conditioning tower of a large cement manufacturer measured 23'' diameter. At an effective height of 70'' the residence time was 78 sec. The gas flow of 240,000 acfm, gave a gas velocity of 570 ft/min. Inlet gas temperature of 400#176;C was to be controlled at 130#176;C. Dust loading measured at about 3040 gr/acfm. For this system, six
