Abstract
A floor (2) of the device communicates with one or more ash-extraction pipes (3) associated with a semi-cooled conveyor. The conveyor is a drag conveyor (5) that travels over a semi-cooled floor (12) inside a housing (4). Several such semi-cooled floors are positioned one above another at several levels. The floors (12) at each level are divided into several tables (16) separated by slots (17) that extend across the direction traveled by the conveyor. The tables are mutually displaced level by level such that the rear end of every table is above the front end of a table in the floor just below it.
