Abstract

1,250,203. Continuous tunnel kilns. A. HASSLER. 9 Dec., 1968 [16 Dec., 1967; 13 March, 1968], No. 58362/68. Addition to 1,120,640. Heading F4B. A continuous tunnel kiln for the reduction firing of ceramics in which the air flow is continuously reversed as in parent Specification has two tracks 14, 15 connected by passages 5 in a dividing wall 16 and fans 2 and 11 at each end producing air circuits 4, 4a, the fan 2 being associated with heat exchangers 3a, 3b incorporating a cooling circuit 6. Roof apertures (8, Fig. 2) with solid fuel stokers (9) feed central grates (12) in the passages 5, ash being collected in a longitudinal passage (10) below the firing zone. A single track tunnel (Fig. 5) has gasometers (17 at each end for reversing the air flow, one of which is associated with cooling tubes (20). The air reversal may be accomplished by a rotary gate valve (Fig. 7) associated with cooling tubes or by bellows (Fig. 8).
