? oven for ceramics with better efficiency?

摘要

an improved efficiency ceramic kiln (1) comprises a channel (5; 105; 205; 305; 405; 505) with a direction (d) for feeding ceramic products and a plurality of burners (7), wherein such a channel ( 5); 105; 205; 305; 405; 505) includes first zones (8, 108, 208, 308, 408, 508) housing at least one burner (7) and second zones (9, 109, 209, 309, 409, 509) without burners (7) such as so that the first zones (8, 108, 208, 308, 408, 508) have a larger cross section than the secondary zones (9, 109, 209, 309, 409, 509) and such that the second zones (9, 109, 209, 309, 409, 509) have a constant cross-section and different cross-section, or variable cross-section, along the longitudinal feed direction (d).
