Title:
HEAT TREATMENT METHOD OF AND APPARATUS FOR INDUSTRIAL WASTES
Document Type and Number:
Japanese Patent JPS5577625
Kind Code:
A
Abstract:
A method and apparatus for the heat treatment of industrial wastes wherein at least some of the constituent materials of the wastes are subjected to combustion and/or to pyrolysis to produce flue gases and, in some applications, a residue. The supply of an oxygenated combustion-supporting gas to the wastes is regulated as a function of at least one sensed predetermined characteristic of the flue gases. The oxygenated gas may be a mixture of air and substantially pure oxygen, the feed rate of one or both of these being regulated in response to the sensed temperature and/or oxygen content of the flue gases. Such regulation maintains the oxygen content of the flue gases within the range of from 0 to 7%; and the temperature of the flue gases may be maintained from 400 DEG to 1200 DEG C. and, preferably within a range of 50 DEG C. in this region.
