DEFINITION

Classification: 202/143

The flues may be in distinct groups which may lie either along or across the heating wall in which they are contained or across the retort, the flame ascending in the flues of one group and descending in those of another group, all the flues

in which the flame ascends in one wall or section of a wall being in connection with one regenerator or regenerator group, and the flues in which the flame descends connected with another regenerator or regenerator group, these regenerators being at right angles to the system and reversal taking place along the system.
