Abstract:
A device for regulating and cleaning an air port (3) arranged in the wall (2) of a furnace, especially a soda house furnace, comprises a cleaning arrangement (1) and an arrangement (4) for regulating the air flow through the air port, in which an air casing (5) is arranged around the air port on the outer side of the furnace wall, in which a drum (12) is arranged inside the air casing and air-tightly connected to the wall of the air casing located opposite to the furnace wall. An opening defined by at least a cover member (14) of the regulating arrangement and at least one lateral wall of the drum is arranged with a restricted extension in the circumferential direction of the drum so as to achieve an air jet in towards and through the air port (3).
Abstract:
Die vorliegende Erfindung betrifft ein Luftjustierorgan, das einen Grundkörper mit einem ersten Kanal, mindestens einer Lochplatte und einer in Strömungsrichtung davorliegenden Abdeckplatte umfasst, mit der der Luftdurchfluss durch die Lochplatte steuerbar verstellbar ist. Die Lochplatte ist auf der vom Koksofen gegenüberliegenden Seite vor dem Kanal angeordnet.
Abstract:
A damper regulator device for adjusting the orientation of a damper blade in an air transfer system, such as a duct, is disclosed. The regulator is coupled to an end portion, of a damper shaft, pivoting of a handle component of the regulator functioning to turn the shaft and hence the blade. The device is adjustable to accommodate damper shafts of different configurations and sizes without disassembly of the device by shifting the handle between one or another of a pair of slots disposed at disparate distances from the shaft. The shifting of the shaft between slots in effected by a channel extending between the slots.
Abstract:
Die vorliegende Erfindung betrifft einen Kühler (10) zum Kühlen von Schüttgut (12), insbesondere Zementklinker, aufweisend einen Kühlgasraum (14), durch den ein Kühlgasstrom zum Kühlen des Schüttguts (12) im Querstrom strömbar ist und eine Fördereinrichtung zum Fördern des Schüttguts (12) in Förderrichtung (F) durch den Kühlgasraum (14), wobei der Kühlgasraum (14), einen ersten Kühlgasraumabschnitt (16) mit einem ersten Kühlgasstrom (26) und einen sich in Förderrichtung (F) des Schüttguts (12) an diesen anschließenden zweiten Kühlgasraumabschnitt (18) mit einem zweiten Kühlgasstrom (30) umfasst, wobei der Kühler (10) eine Trennvorrichtung (34) zur gastechnischen Trennung der Kühlgasraumabschnitte (16, 18) voneinander aufweist, wobei die Trennvorrichtung (34) eine Mehrzahl von Abdichtungselementen (42) und zumindest ein Aufhängungselement (40) aufweist, an dem eine Mehrzahl von Abdichtungselementen (42) angebracht sind.
Abstract:
The invention provides a stove which includes a fuel tank 12 for storing a liquid hydrocarbon fuel 14 for combustion in the stove. A frame 16 made of sheet metal secures the tank 12 to a cooker portion 18 and permits feet 20 of a synthetic material such as PVC to be snapped into position to provide a stable base for the stove 10 when it stands on a surface such as a table or a counter. The tank 12 has in a central portion 22 thereof a ceramic porous element 24 made of a ceramic fibre mat which is spirally wound into a cylindrical shape with spaces so that the element 24 may retain a liquid hydrocarbon fuel such as ethanol. A burner 30 is secured in position above and in flow communication with the tank 12 with a cylindrical length 28 bridging the gap between the element 24 and the burner 30. A combustion chamber 40 is made of a base portion and an upper dished portion made of sheet metal 50, 52, the upper dished portion 52 having a conical, funnel-like, recessed portion 53 in which the apex of the cone or funnel is directly downwardly towards the tank 12 and has an opening in flow communication with the contents of tank 12.
Abstract:
A device is supplying combustion air to a combustion chamber (11), in which solid fuel is being burned, and the air supply is controlled in accordance with at predetermined program as a function of combustion time. The predetermined program is preferably based on empirical data. The combustion air may be supplied by means of a valve member (13), which is displaceable between first and second positions, and the valve member may expose varying areas of air supply opening(s) (12, 14) when moved between said positions. Biasing means (15), such as spring means, may bias the valve member (13, 17) towards said second position and slowing-down means may delay the movement of the valve member.
Abstract:
The invention relates to an arrangement for cleaning, airflow control and where appropriate pushing away melt in air ports of recovery boilers within the paper and pulp industry. By inclining the regulating device (10) at an angle to the horizontal plane and at the same time making the piston of the regulating device run in contact with the side and upper walls (24a, 24b) and, respectively, (22) of the air port, optimum airflow control and a more compact installation can be achieved. The airflow can be adjusted more rapidly with a small regulating movement at the same time as very good penetration of the air into the furnace (4) is achieved. The regulating device is allowed to penetrate into and down into the furnace so that the regulating device can push away any melt/slag in the event of a high level of melt (3) in front of the opening (30) of the air port into the furnace (4).
Abstract:
A vent that includes: a rotary head with blades arranged between a top and bottom section of the rotary head; a fixed component to mount the rotary head to a roof of a building, the fixed component having a throat that provides a flow path from inside the building to an interior of the rotary head; and a diffuser to split airflow vented from the throat and direct the vented airflow out through the rotary head.
