摘要： The present invention concerns a method and device for closing off one or more passages in a ring furnace for calcining of carbon bodies in which the furnace, during the calcining process, over an area comprising a small number of sections, is divided into a preheating zone, a firing zone and a cooling zone, which are together successively moved forwards in the furnace. In order to control the false air intake from a first section (K-1) before the preheating zone to the first section (K1) in the preheating zone, one or more lowerable air dampers (4) are placed in the head wall (2). When the air damper (4) or air dampers is/are lowered, it/they blocks/block the supply of false air from the first section (K-1) before the preheating zone to the first section (K1) in the preheating zone.

摘要： A thermally compensated structural element (1) comprising an upper element (2) and a lower element (3). The upper element consists of an angle section with a mainly horizontal part (15) and a mainly vertical part (16). The lower element (3) is designed with a base part (17) and a vertical part (18). The upper element (2) and the lower element (3) are both connected to connection elements (5, 6, 7, 8, 9) in such a way that thermally induced expansion/contraction is compensated for. The solution comprises further features which will contribute to preventing distortion of the structural element. Structural elements of the above type may be used in a base frame for covers which are used in thermal processes such as section covers for use in furnaces for calcining of carbon bodies.

摘要： The present invention concerns a wall structure and a method for constructing such an anchored wall structure. The wall structure is designed for use in a furnace or the similar, where the structure is exposed to cyclical thermal load. The structure consists of a row of individual elements which are placed in the longitudinal direction of the structure and are arranged in one or more courses, one resting on the other. The individual elements may consist of bricks of refractory material and the wall structure may also be provided with internal flue gas ducts. The wall structure is also designed to be able to compensate for longitudinal changes and any vertical changes as a consequence of cyclical thermal load. The wall structure's longitudinal changes are compensated for in a connection (2) arranged at least one end of the wall structure. The structure's individual elements are fixed to each other in the horizontal direction by means of mutually interacting contact elements. This produces a structure which remains stable after repeated thermal cycles, and costs related to restoration and stoppages can be reduced.

摘要： The present invention concerns a method for creating a thermally stable base structure which may form part of furnaces and means in connection with such a method. In particular, the present invention concerns base structures which may form part of ring furnaces for calcining of carbon blocks for use in aluminium electrolysis. The base structure rests on a foundation consisting of a number of columns (15, 16, 17, 18, 19, 20) and is created by a first layer B' of refractory bricks being laid on the foundation. These bricks are made with locking elements (25, 26) on their tops, onto which is laid a second layer C' of refractory bricks with equivalent, complementary locking elements underneath them. In this way, the two layers are connected to each other and a structure is achieved which has proved stable in relation to thermal and mechanical loads.

摘要： The present invention concerns a method and a device for connecting firing gas passages in an outermost section in one row in a ring furnace for calcining of carbon bodies to firing gas passages in the matching outermost section in the parallel row via a connecting duct (1). The active flow cross-section in the connecting duct (1) is gradually reduced in the direction of flow of the firing gas by installing a flow director (2) inside the connecting duct (1). This results in the firing gases being distributed as evenly as possible between the firing gas passages (6, 6') in the head wall (7) and problems associated with uneven gas distribution in the first sections in the furnace rows being minimised.
