IPC: F23C99/00
Filed: 1983-02-16
Abstract: PURPOSE:To reduce bad influence on the environments by a method in which oxides such as NOX, SOX, etc., are burned in an oxidative conduction, soon reduced by ambient reductive atmosphere to restore it to a stable condition, and discharged to the outside of a furnace. CONSTITUTION:The main constituent substances H2 and CO of a combustion gas to be sent through an inlet port 4 are oxidized by O2 in air sent from an inlet 3 to form H2O and CO2, and energy is released. The heat energy of exothermic reaction is taken out through a heat medium constituting a heat transfer device 10 to the outside of the furnace 2. In this case, such substances as Li, K, Ca, Na, Mg, etc. showing a cation ionization tendency at high temperatures are charged into the furnace 2 to form a reductive atmosphere. For this reason, oxides such as NOX and SOX are converted into most stable substances N2 and S2 by the actions of high-temperature heat energy and also of reductive atmosphere and discharged to the outside of the furnace. Bad influence of these oxides on the environment can thus be reduced.

Abstract: PURPOSE:To attain normal exchange even when a phase difference exists between input data by using an input clock, a clock different from a frame pulse, and a frame pulse itself so as to latch the input data thereby absorbing the phase differencd of the input data. CONSTITUTION:One frame's share of input data subject to multiplex in channels #0-#3 from an input highway 1 are fetched to an input data latch 10 by using a clock C1 and a frame pulse F1 inputted at the same time via a shift register 2.

The data are subject to exchange connection by a control memory shift register 4 and an output register 5 and read to an output highway 6. Thus, the phase difference between input data due to the difference in the length of input highways is absorbed by a time switch for one frame's share, and even when the input highway length is different between the highways, the exchange operation synchronized with the clock and frame pulse are attained.
