Abstract:
This invention is directed to a method for carrying out combustion in a furnace having porous walls with a large surface area comprising providing a combustion zone containing an atmosphere of furnace gases. A low velocity oxidant stream is injected through at least one oxidant injection side of the porous walls into the combustion zone and mixing furnace gases with the oxidant stream in a mixing zone within the combustion zone to produce an oxidant mixture. A fuel stream is injected through at least one fuel injection side adjacent to the oxidant injection side in the combustion zone. The oxidant mixture is mixed with the fuel stream to create a fuel-oxidant mixture.
Abstract:
An insulating glass door for a cooking chamber of a cooking appliance is formed by an insulating glass window composed of two individual panes which are spaced apart for forming an interspace therebetween, which is sealed by an insulating material. The door includes at least one door component which is integrated and extends between the two spaced-apart panes.
Abstract:
A warp resistant fuel feed door assembly for use in injecting supplemental fuel into a high temperature combustion chamber such as a rotating cement kiln without substantial loss of heat or combustion gases. The apparatus, which is positioned on the exterior side of a fuel passage transecting the wall of a rotating kiln, opens to receive fuel and then seals during the balance of the rotation of the kiln. Warping, bearing fracture, shaft distortion and jamming due to exposure to extreme heat and cooling are minimized by the sectional construction of the doors. The door includes a plate positioned over the mouth of the passage, a plurality of support arms attached to the plate and a hinge shaft attached to the arms. Stresses on the door structure from inconsistent expansion of the plate are reduced due to symmetrically spaced oblong and oversized bolt attachment bores in the support arms. Synchronous opening of the feed doors is achieved by levered rotation of the hinge shafts by an electric motor. Selective introduction of supplemental fuel into a rotating kiln can be controlled by electrical actuation of the feed doors.
Abstract:
A fill door for use on the angled surfaces of furnace shells and chemical containers. The door (16) is pivotally coupled to a door frame (18) integral with the angled surface and includes a rim (26) that mates with a female channel (28) in the door (16). A U-shaped latch is pivotally connected to the frame (18) and includes a threaded spindle operatively connected to a crank. The surface of the door (16) includes a female sleeve having a bore for accommodating the end of the spindle when the latch is over the door (16) and the spindle is tightened into its closed and locked position. The door (16) further includes a cantilevered arm having an angled bore which allows it to swivel around a substantially vertical cylindrical post connected to frame. The arm and door swing in a substantially horizontal plane around the axis of the post.
Abstract:
A motorized door latch assembly for locking an oven door in a locked and sealed position for purposes of cleaning the oven. A motor assembly causes a latch rod to translate, causing a latch plate to move between different positions. In a first position, the latch plate allows the oven door to open. In a second position, the latch plate prevents the oven door from opening. In a third position, the oven door is pulled inwardly to a locked and sealed position. During shipment, the latch plate is locked in its first position by a fixer. The distance between the latch plate and the motor assembly may be adjusted for ranges of different sizes.
Abstract:
A fireplace including a combustion chamber enclosure with an opening and an inner pane positioned to at least partially cover the opening of the combustion chamber. An outer pane is spaced apart from the inner pane, the outer pane and the inner pane creating a space through which air moves, the air cooling the outer pane. A blower may be provided to move the air through the space. The outer pane may be angled with respect to the inner pane to enhance air movement.
Abstract:
The invention relates to a hinge for a stove door, comprising a housing (1) in which a plug-in part (2) is rotationally (10) mounted. In order to be able to easily influence the torque produced by the spring, a spring guide (3) which is loaded by a spring (6), preferably a pressure spring, is provided, said spring guide being fitted with roller (15) that is guided through a curved section (9) of the plug-in part (2).
Abstract:
A cooking oven includes a heatable oven chamber (6) that can be loaded with product from the outside area (A) through a loading port (8). An oven door (10) serves to close off the loading port (8) of the oven chamber (6) from the outside area (A). An inner pane (50) faces the oven chamber (6), an outer pane (48) faces the outside area (A), and one or several intermediate panes (52) are positioned between the inner pane (50) and the outer pane (48). An outer cavity (54) is between the outer pane (48) and the neighboring intermediate pane (52) and an inner cavity space (56) is between the inner pane (50) and the neighboring intermediate pane (52). A cooling system moves cooling air (K1) through the outer cavity (54) while thermally insulating air (I) can be held stationary in the inner cavity (56).
Abstract:
A cooking appliance includes a cooking chamber that can be closed by a door having a multi-pane structure, including at least one inner pane and one front pane. The invention configures the cooking appliance such that the surface temperature on the outer side of the front pane is as low as possible. To this end, the inner pane is embodied in a tray-like manner and is fixed to the front pane by holding elements that are disposed on the inner side of the front pane inside the circumferential edge of the inner pane.
