Glass-melting electric furnace with elevated bottom of melting portion

摘要

Glassmaking electrofusion dog with elevated bottom (3) of the melter (1) includes at least two basic increase (10, 10a, 10b) which are identical in shape and identical at each river cut relative to the longitudinal axis (9) of the melter (1 ) are arranged each in mirror relation to the longitudinal axis (9) at least a portion of the melter (1) between the end walls (4) and a rear wall (5) and spaced from the side walls (6, 7) equipped with heating electrodes (8, 8a) and are facing the submerged flow (2) and the flow of the rear wall (5) or are associated with it. Basic increase (10, 10a, 10b) have between their mutually facing walls arranged longitudinally connecting channel (12), preferably at the level of the bottom (3) of the melter (1). Elevated bottom (3) of the melter (1) further comprises at least one from initial increase (10, 10a, 10b) separated, prolonged increase (100, 100a, 100b) which is identical at each cross-section perpendicular to the longitudinal axis ( 9) is spaced from the side walls (6, 7) equipped with heating electrodes (8, 8a), facing the front wall (4) of the melter (1), and is optionally connected with it. Between the facing walls of prolonged increase (100, 100a, 100b), and increase the base (10, 10a, 10b) is arranged transverse connecting channel (12a) forming longitudinal connecting channel (12) shaped channel T. All elevations (10, 10a, 10b, 100, 100a, 100b) have their top surface or edge submerged below the surface of molten glass (11) and preferably below half the height of the level of molten glass (11). Increase (10, 10a, 10b, 100, 100a, 100b) can have either constant or variable cross profile to the longitudinal axis (9), or in the direction perpendicular to the longitudinal axis (9) of the melter (1). Basic increase (10, 10a, 10b) may be identical or different design solutions due to the prolonged increase (100, 100a, 100b). Increase (10, 10a, 10b, 100, 100a, 100b) may have tapered surfaces continuous, broken, or cascade, and variably chosen maximum height (H) and / or a maximum width (W, W1) and / or maximum length (L , L1).
