Title: Waste toner recovering device
Inventor: IWASAKI SHINICHI
IPC: G03G21/10
Filed: 1984-01-18
Abstract: PURPOSE:To store as much waste toner as possible in a recovery container by forming an opening in a screw conveyor casing for waste toner so that toner becomes easier to fall from the upstream side to the downstream side. CONSTITUTION:A screw conveyor 2 is arranged over a waste toner recovery container 4 and surrounded with the casing 2a which has a slit 5. The slit 5 is so formed as to deviate from a center axial line 6 at the upstream side in a conveyance direction and coincide with the axial line 6 at a downstream side. Toner is hard to fall at the upstream side and becomes easier to fall toward the downstream side. Consequently, a nearly uniform amount of toner falls in the container to the overall length of the conveyor 2 and is never omnipresent locally, so that as much waste toner as possible is stored in the container 4.

Title: Operation of denitrating device for combined plant
Inventor: WADA TOSHIMICHI
IPC: B01D53/94
Filed: 1982-01-21
Abstract: PURPOSE:To enable an operation of the plant at a low NOX concentration without degrading the heat efficiency of the plant by a method wherein when the temperature of exhaust gas is relatively low, the generation of NOX is suppressed by an injection of water or steam, whereas when the temperature is relatively high, by ammonia reduction. CONSTITUTION:At the timepoint when the exhaust gas temperature exceeds the lower temperature limit of a denitrating device of ammonia reduction due to an increase in load after a denitration by the water or steam injection at the starting of the plant, the denitration by the denitrating device is also used (see curve C6 in the graph), and when the effect appears, the denitration by the water or steam injection is stopped. Thereafter, the denitration is performed only by the denitrating device. As the denitration by the water or steam injection is not carried out on the gas turbine side during a normal operation of the plant, a heat loss can be decreased, thereby improving the total efficiency of the plant.
