摘要： A stable continuous production of a propylene-based block copolymer can proceed for a long time without causing accumulation of particles having a small diameter by a process having the following steps: (1) polymerizing an &agr;-olefin containing liquid propylene as a main component in the presence of hydrogen and a stereoregular polymerization catalyst in one or more polymerization reactors to obtain a polymer slurry; (2) feeding the polymer slurry to a copolymerization reactor; and (3) copolymerizing propylene and an &agr;-olefin other than propylene substantially in a gaseous phase in the presence of the stereoregular polymerization catalyst, the polymer slurry and a deactivating compound in the copolymerization reactor to obtain a propylene-block copolymer powder. The polymer slurry, discharged from one of said one or more polymerization reactors and is classified using a classification system to obtain a) a classified polymer slurry containing a large amount of particles having a small particle diameter and b) a classified polymer slurry containing a large amount of particles having a large particle diameter. A main part of the classified polymer slurry containing a large amount of particles having a small particle diameter is recycled to a final polymerization reactor of the one or more polymerization reactors.

摘要： A burner 1 for combustion chamber is provided with a cylindrical mixing portion 3 that mixes air for combustion (oxidizing agent) and fuel in the interior thereof and has one end 3a that opens to a combustion portion 2; a spray nozzle (fuel spraying portion) 5 that sprays fuel in the mixing portion 3, being disposed on another end 3b of the mixing portion 3; first blowing ports 6 that introduce the air for combustion to the mixing portion 3 to form a swirling flow with the fuel, being disposed to open to the inner wall of the mixing portion 3; and second blowing ports 7 that additionally introduce the air for combustion to the mixing portion 3, opening in a direction different from the first blowing ports 6 and being disposed further to the other end 3b side of the mixing portion 3 than the swirling flow. The burner for combustion chamber and combustion method of the present invention can shorten the flame length in the central axial direction by improving the combustion efficiency even during low loading and shorten the overall length of the burner for combustion chamber in the central axial direction.
