FLUIDIZED BED COMBUSTOR OR GASIFIER FOR APPLICATION IN PRESSURIZED SYSTEMS

摘要

PURPOSE: To attain a minimum size of a pressurized container in such a manner that a combustion chamber is made to have a non-symmetrical horizontal cross section and a plurality of adjoining walls may form a predetermined angle. ;CONSTITUTION: A combustion chamber 12 to be stored in an upright cylindrical steel container 18 is formed by a vertical flat tube panel having a trapezoidal section formed by the longest side wall 22, a short side wall 24 and two end walls 26, 28. Then, at least two adjoining approximate straight walls, for example, walls 24, 26; and 24, 28 may form an angle larger than those above by 90°. Then, the combustion chamber 12 is arranged in the first half section of a pressure container 18, and a long side wall 22 is arranged at a substantial central part of the pressure container 18. Then, a short side wall 24 and end walls 26, 28 are arranged in the vicinity of the periphery of the pressure container 18. Then, the combustion chamber 12 and a cyclone can be arranged efficiently and a useless space of the pressure container 18 can be made minimum.;COPYRIGHT: (C)1995,JPO
