HEAT INSULATING MATERIAL UTILIZING CARBON COMPONENT RECOVERED FROM CINDER AND DUST AND METHOD SUPPRESSING DISCHARGE OF AIR POLLUTANT FROM COMBUSTION EQUIPMENT BY THIS HEAT INSULATING MATERIAL

摘要

PROBLEM TO BE SOLVED: To provide a heat insulating material, recovering a carbon component from a cinder and dust to be disposed as industrial waste to utilize a heat insulating characteristic thereof to heat insulate air or fuel gas supplied to a combustion equipment and a flow pipe so as to suppress discharge of an air pollutant from the combustion equipment, and a method utilizing this heat insulating material to suppress discharge of the air pollutant from the combustion equipment.;SOLUTION: A material 1 refining a carbon component separated from a cinder and dust to increase a carbon content to about 90% or more is formed as a heat insulating material sealed in a plastic-made protruding bag or vessel 2 having water-tightness, durability, and heat insulation. This heat insulating material is mounted in a flow pipe of air or fuel gas supplied to a combustion equipment to serve as a method suppressing discharge of an air pollutant from the combustion equipment.;COPYRIGHT: (C)2001,JPO
