Title:
VOLUME REDUCTION TREATING METHOD AND APPARATUS FOR ASH
Document Type and Number:
Japanese Patent JP3750027
Kind Code:
B2
Abstract:
PURPOSE: To enable an easier maintenance and a conservation of heat energy with a simple system.
CONSTITUTION: This volume reduction treating method of ash preheats ash by a burning means 7 in melting furnace 13 while melting the ash to reduce the volume thereof. At least a part of a high temperature exhaust gas from the melting furnace 13 is induced by an ejector 25 to mix the high temperature exhaust gas and a drive fluid of the ejector 25 with the ejector 25, a mixed gas mixed and adjusted in temperature is discharged to an outlet piping 18 from the ejector 25 and the ash is introduced into the outlet piping 18 while being conveyed on current being preheated by the mixed gas to be separated and recovered. The ash thus obtained is supplied to the melting furnace 13. This can prevent trouble such as gas leakage from the melting furnace with a simple structure, thereby improving safety and reliability.
