  • Process for the operation of a regenerator and regenerator
    Patent number: 6334265
    Abstract: The invention relates to a process for the operation of a regenerator, hot and cold gas being repeatedly passed through a bulk material 4 with a maximum particle diameter Dmax which is received in the annular space 1 between a substantially cylindrical hot grid 3 and a cold grid 4 surrounding the latter, and at least one discharge opening 16 being provided in the bottom B of the annular space 1 for discharging the bulk material 4. To increase the service life of the regenerator, it is proposed according to the invention that a predetermined amount of bulk material 4 is discharged during or after the passing-through of hot gas, so that a compressive stress exerted by the bulk material 4 on the hot grid 3 and cold grid 4 is reduced.
