Abstract

PURPOSE: To prevent troubles due to ignition and fire spreading of ash in an ash storage tank by carrying out an operation for transporting collected ash to a first ash storage tank from an electric dust collecting machine and another operation for transporting ash to a second ash storage tank from the first ash storage tank in a different time zone.
CONSTITUTION: Transportation of ash to a first ash storage tank 5 from a lower hopper of an electric dust collecting machine 1 and transportation of ash to a second ash storage tank 8 from the first ash storage tank 5 are carried out in a different time zone and, further, an ash storing level in the first ash storage tank 5 is made higher than that of the second ash storage tank 8. In order to smoothly carry out ash falling from a lower cone part and a chute part, in the second ash storage tank 8, an aeration seat 9 is provided but, when ignition source is mixed, because fire spreading of the ash is promoted if air is sent from a lower part thereof, an inert gas such as a nitrogen gas or the like is blown thereinto from the aeration seat 9 to lower the concn. of oxygen and, thereby, the fire spreading of the ash is prevented.
