摘要： Removable apparatus for regulating air flow through an air port in a chemical recovery furnace. A plenum mounted adjacent an air port inside a wind box associated with the furnace supplies combustion air from the wind box to the furnace through the air port, and an adjustable damper mounted inside the plenum regulates the velocity and quantity of air flowing through the plenum. An access port in the plenum allows viewing of the air port opening through the plenum. An actuating mechanism withdraws the damper from the field of view to a retracted position wherein the damper depends from the top of the plenum chamber spaced apart from the air port opening. For airflow damping, the actuating mechanism moves the retracted damper toward the air port opening until the damper is adjacent to the opening; then a positioning mechanism pivots the damper to a predetermined position in the air stream adjacent the opening. The damper positioning mechanism comprises a spring loaded cylinder that holds the damper by spring tension, when retracted, above the flow of air through the plenum chamber. Upon further compression of the cylinder by the actuating mechanism, the reduced length of the compressed cylinder forces the damper downward into the air stream. When the actuating mechanism is reversed, the spring tension of the compressed cylinder pulls the damper upward to the retracted position.

摘要： A draft control system for furnaces comprises an auxiliary channel in communication both with ambient air and the flue of the furnace, a main draft control means for regulating the entrance of ambient, auxiliary draft air into the flue, and auxiliary draft control means mounted in the auxiliary channel for dampening the effect of extreme changes in external conditions on the main draft control means. Thus, uniform draft and efficient combustion is maintained in the furnace under a wide variety of conditions. The main draft control means comprises counter-balanced draft control plates which are initially set in an open position so that they can either open or close in order to efficiently regulate the draft in the flue. The auxiliary draft control means comprises, in one embodiment, an isolation damper plate rotationally mounted in the auxiliary channel, or, in a second embodiment, a set of louvred panels. The position of the auxiliary draft control means is automatically regulated by a pneumatic control device responsive to the efficiency of furnace combustion.

摘要： A draft control plate, which automatically opens or closes to provide efficient draft conditions in a furnace, is provided with both horizontal and vertical counterbalance devices which respectively permit adjustment of the initial position of the plate and the sensitivity of its movements. Initially, the plate is partially open where it remains while the furnace is operating under normal conditions. It is then capable of opening or closing in response to changes in the pressure differential across it. Preferably, the plate is horizontally mounted in an auxiliary flue channel which is adjacent to and in connection with the main flue of the furnace.

摘要： Apparatus for cooperation with an associated flue having a first axis extending away from a point proximate to an associated combustion chamber which includes a funnel shaped member having first and second ends. The second end is larger than the first end. A damper is disposed in the associated flue which has a generally central bore. The damper is mounted in the associated flue for rotation about a second axis which is generally perpendicular to the first axis and the funnel shaped member is mounted with the first end higher than the second end and with the second end extending into the damper. The mounting for the damper may comprise at least one rod shaped member extending through at least one wall of the associated flue. The mounting for the funnel shaped member may comprise a plurality of elongated members extending radially from the funnel shaped member to the associated flue. In another form of the invention a first duct is disposed within a second duct which is in fluid communication with an associated flue. The first duct may be rectangular in cross section and generally planar members may be selectively pivoted to restrict flow intermediate the first and second ducts. The first duct will ordinarily have no restriction on the flow of exhaust gases other than the restriction inherent in the inner duct.

摘要： A thermostat for a stove is disclosed. The thermal control unit is contained in a housing which has an aperture formed therein and includes a thermal control unit for detecting changes in the temperature of the stove. A flap is secured to the housing and is rotatable across the aperture so as to cover the aperture to any desired degree. The thermal control unit controls the position of the flap to control the effective area of the aperture, thereby to control the amount of air supplied to the stove. The thermal control unit, the flap and the aperture cooperate to ensure that the effective area of the aperture changes by an amount approximately proportional to the square of the magnitude of any change in the stove temperature detected by the thermal control unit. The thermal control unit may preferably comprise a bimetallic coil or a liquid expansion thermometer. At least one edge of the flap, or at least one edge of the aperture, or at least one edge of each is curved in such a manner as to produce the desired change in area, in cooperation with the thermal control unit, responsive to stove temperature changes.
