Abstract: The optimum cycle time to schedule sootblowing of a boiler (10) is predicted using on line process measurements. The optimum cycle times dynamically adjust to changing conditions resulting from boiler operation, fuel changes, or seasonal changes. The optimum cycle time is calculated four times per second for each heat trap (12, 13, 14, 16, 18) of the boiler (10). The optimum conditions are based on economic criteria which account for heat trap fouling, rate of fouling of other heat traps within the boiler, and on line boiler incremental steam cost.

Abstract: A power sieve has a generally planar and longitudinally extending frame having upstream and downstream ends and a pair of laterally spaced side members extending longitudinally between the ends, a generally planar screen spanned longitudinally within the frame, and a plurality of longitudinally spaced and substantially parallel beater beams underneath the screen and having beam ends juxtaposed with the frame side members. Respective horizontally extending leaf springs each have one end secured to the respective side member and another end secured to the respective beam end. Thus the beams can move generally vertically on the springs. Respective beater arms extending generally parallel to the screen from the beater beams have outer ends engageable with the underside of the screen. In addition, respective actuation arms extending radially from the beater beams have outer ends connected to a rigid longitudinally extending link connected in turn to a linear drive on the frame connected to the link for horizontally reciprocating the link and thereby simultaneously and synchronously pivotally oscillating the beater beams with the respective beater arms to hammer the outer ends of the beater arms against the screen. In this manner when the screen is inclined down from the one end and particulate material is loaded onto the screen at this end the particulate material migrates down along the screen to the other end with the smaller fractions falling through the screen.

Abstract: The ignition system of a five-cylinder gasoline engine utilizes two ignition coils, each serving two cylinders which are fired at instants of the firing sequence which are separated by the firing of one of the cylinders served by the other of these ignition coils. A third ignition coil fires only the remaining cylinder. The sparkplugs of two cylinders fired by the same ignition coil are connected through oppositely poled diodes. This arrangement avoids circuit closing sparks when either of the twin primary windings of the ignition coils serving two cylinders is turned on. There are thus five separate primary windings and only three separate secondary windings, and the former are turned on and off by individual electronic switching circuits triggered in sequence by individual pulse generators responsive to a magnet on a single rotary disc.
