Abstract: An apparatus for feeding waste tire chips (12) to an incinerator (11) having a feed chute (13) comprises a container (17) provided with a screw feeder (22, 23) at its bottom, upper and lower two vibrating feeders (24A), (24B), and a transfer conveyor (36) extending between the lower vibrating feeder (24B) and the feed chute (13). The screw feeder (22, 23) is controlled by a first controller (34) in response to an output signal from a first photoswitch (33) which is mounted on the upper vibrating feeder (24A) for detecting the quantity of chips delivered from the container (17). The transfer conveyor (36) and the lower vibrating feeder (24B) are controlled by a second controller (42) in accordance with an output signal from a second photoswitch (41) which is mounted on the feed chute (13) for detecting the quantity of chips to be fed to the incinerator (11) at a time. The upper vibrating feeder (24 A) is intermittently operated by a third controller (43).

Abstract: An apparatus for feeding waste tire chips to an incinerator comprises a chip container having a front wall, a rear wall and an outlet at the lower end of the front wall, and a screw feeder having a shaftless helical screw blade provided at an inner bottom portion of the container. The screw blade has one end supported by a first bearing provided on the rear wall of the container and the other end projecting from the outlet of the container. The other end of the screw blade is supported by a second bearing disposed outside the container outlet. Waste tire chips can be fed to the incinerator stably at all times.

Abstract: An apparatus for removing non-condensable gas accumulated in the exchanger tubes of a heat exchanger. A vertically elongated tank having retained in its lower portion a liquefied working medium for the exchanger tubes is provided beside the heat exchanger. The tank communicates as its lower portion with the lower ends of the tubes and at its upper portion with the upper ends of the tubes by lines each provided with a valve. A gas release pipe extends downward from outside into the upper portion of the tank through the tank wall. A working medium condensing cooling tube is provided in the upper portion of the tank. The interior of the tank is partitioned into a condensing tank and a tank main body positioned therebelow and having an upper portion communicating with the upper portion of the condensing tank and a lower portion communicating with the lower portion of the condensing tank.
