Abstract:
A multi-oil fired furnace having a heat exchanger that extends rearwardly of the combustion chamber and utilizes laminar air flow around the combustion chamber to minimize the width and height dimensions of the cabinet shell for the furnace. The heat exchanger includes an exhaust header having a central opening and a cluster of concentrically arranged exhaust tubes connected to the combustion chamber. A vertical baffle forces the flow of air through a central opening that is concentric with the combustion chamber into a group of horizontal baffles directing the air into a generally laminar flow pattern against the outer surface of the combustion chamber before being discharged from the cabinet shell in a selected one or more of three possible directions. The fan control switch is mounted on a mounting plate that is welded to the combustion chamber to provide a planar contact surface for the switch mechanism.

Abstract:
A multi oil furnace is disclosed wherein the front door is sealable against the burner chamber and against a lip extending around the circumference of a front header formed in the cabinet shell to operatively interconnect an upper bank of heat exchanger conduits with a lower bank of heat exchanger conduits. The exhaust gases flow from the burner chamber into the upper bank of conduits to the front header where the exhaust gases must flow around the burner chamber to the lower bank of heat exchanger conduits. The lip extending around the periphery of the front header is recessed below the lower bank of conduits to permit an accumulation of ash precipitated from the exhaust gases. The front door carries longitudinally offset sealing surfaces to seal against both the burner chamber and the header lip. Both the upper and lower banks of conduits, the burner chamber and the front header are accessible through the opening corresponding to the front door when moved to its opened position.

Abstract:
A multi oil furnace is disclosed wherein the external cabinet shell houses a central burner chamber, an upper bank of conduits and a lower bank of conduits. Headers operably coupling the burner chamber, the upper and lower banks of conduits and a discharge opening define a flow path for the combustion gases created by the ignition of the used oil within the burner chamber. A ventilation chamber positioned between forward and rearward headers allows the passage of ambient ventilation air around the conduits and the burner chamber to effect a transfer of heat from the exhaust gases to the ventilation air while maintaining isolation therebetween.

Abstract:
A control device for the discharge deflection spout on a forage harvester is disclosed wherein the discharge end of the spout is rotated in a substantially horizontal plane even though the base of the spout is rotated about an axis defined by the blower which is tilted at an acute angle to the vertical.

Abstract:
A compartmentalized housing for the operative components of a multi oil furnace is disclosed wherein the first housing compartment contains an integrated preheater block and operative controls for the flow of used oil and compressed air to the burner assembly, which is cantilevered from the preheater block and positioned within the second housing compartment. The second housing compartment rotatably supports a combustion air fan to draw combustion air through an inlet opening in the second housing and blow the combustion air into the burner chamber over the burner assembly, which is configured and oriented to minimize combustion air turbulences. The fan motor is supported within the third housing compartment. Each of the housing compartments is provided with a removable cover to permit access to the respective component housed therein. The removable cover for the second housing compartment mounts the electrical power supply for the flame igniter so that the power to the igniter is disconnected whenever the cover is removed.

Abstract:
A preheater block for a multi oil furnace is disclosed wherein the metallic preheater block is formed with a separate heater chamber housing a heating element to provide conductive heat throughout the preheater block which is provided with a first flow path defining multiple passes through the preheater block to raise the temperature of the flow of used oil therethrough to a predetermined level. An oil flow regulator is coupled to the first flow path to permit a manual regulation of the rate of oil flow through the preheater block after the used oil has attained the predetermined temperature. A second flow path is defined within the preheater block to allow a flow of compressed air therethrough to reach substantially the same predetermined temperature as the used oil.

Abstract:
A self-propelled forage harvester having a longitudinally extending mobile frame supported by a pair of forwardly disposed transversely spaced wheels is disclosed wherein a transfer chute having a pivotally mounted frame guides crop material from the cutterhead to the discharge blower. The cutterhead is mounted on the forward portion of the mobile frame and includes a housing having a rear crop outlet opening. A shear bar is mounted adjacent the path of a plurality of knives affixed to the rotatably mounted transversely disposed cylindrical cutterhead, the knives cooperating with the shear bar to cut crop material and throw it rearwardly through the crop outlet opening. A crop discharge blower unit having a housing with a crop inlet opening aligned with the crop outlet opening of the cutterhead housing is mounted on the frame behind the cutterhead. The crop transfer chute guides crop material being thrown through the crop outlet opening by the rotating cutterhead to the crop inlet opening in the blower housing. The transfer chute includes a pivotally mounted frame which is selectively positionable between operative and inoperative position to provide a convenient access to the cutterhead and blower units.

Abstract:
A coil tube heater for a multi-oil burner in a used-oil fired furnace utilizing an air to liquid heat exchanger and being fabricated from tubing formed into a tightly coiled cylinder having a plurality of coil loops that are not fixed to any of the adjacent loops to allow for unfettered heat expansion. The coil tube heater is provided with a ceramic sleeve interposed between the burner assembly and the coiled heat exchanger to focus the flame into a tight configuration toward the target positioned at the rear of the combustion chamber. The coil tube heater is provided with a circulation system that has a first circulation loop having a first circulator that moves a liquid transfer medium through the coiled heat exchanger to a buffer tank or directly to the load. A second load loop has a second circulator that draws heated transfer medium from the outlet line leading from the coiled heat exchanger to a load cell before injecting the cooled transfer medium into the inlet line leading back into the coiled heat exchanger.
