Abstract: Carbon dioxide in combustion exhaust gas can be effectively separated and the combustion exhaust gas including the other exhaust gas components condensed through the separation of carbon dioxide can be discharged to the atmosphere.Air 7 is separated by an air separation unit 8 into oxygen 9 and other nitrogen-prevailing gas 10a. The obtained oxygen 9 and coal 1 are burned by a burner 5a of a combustion furnace 4. Exhaust gas treatment is conducted for the resultant combustion exhaust gas from the furnace 4. Then, part of the combustion exhaust gas is recirculated to the burner 5a and the remaining unrecirculated combustion exhaust gas is compressed to take out liquefied carbon dioxide 29. The other exhaust gas components 31 unliquefied through the compression is mixed and diluted with the other nitrogen-prevailing gas 10a in the separation of the oxygen 9 from the air 7 in the air separation unit 8 and is discharged to the atmosphere.

Abstract: Separation functional fibers are produced by exposing fibers with a core/sheath structure to an ionizing radiation and then grafting a polymerizable monomer to the fibers. Ion-exchange fibers are produced by introducing, through radiation-initiated graft polymerization, ion-exchange groups into the sheath of each of composite fibers the core and the sheath of which are composed of different kinds of high-polymer components. The separation functional fibers and the ion-exchange fibers are useful in various applications such as the production of pure water in electric power, nuclear, electronic and pharmaceutical industries and the demineralization of high-salt content solutions in the production of foods and chemicals. The fibers are also useful in removing harmful components from gases, as well as odorous components such as ammonia.

Abstract: A fire extinguishing device for an oil burner capable of instantaneously and surely accomplishing the fire extinguishing with ease and without generating any bad odor. A wick receiving chamber has a width larger than the thickness of a wick received therein and an air chamber communicated to the wick receiving chamber is disposed adjacent thereto. The air chamber is adapted to be communicated to an ambient atmosphere during the combustion operation and to be shut off therefrom by means of a valve. The fire extinguishing of an oil burner is accomplished by utilizing an air stored in the air chamber.
