Car Bottom Heating Furnace for Annealing Furnace

Car Bottom Furnaces
ELECTRICALLY HEATED OR GAS FIRED
Car Bottom Furnaces
bonade manufactures car bottom furnaces in either electric or gas fired heating systems. The design of the heating systems provide for shielding of the loads from the detrimental effects of direct radiant heat or flame impingement while promoting efficient uniform heating of the loads.
ELECTRIC HEATING SYSTEMS
Electric furnaces employ various styles of resistance type electric heaters to maintain the integrity of the furnace atmosphere and thermal efficiencies. Heaters can be supplied as either standard open resistance wire type, or bayonet/radiant tube style based on the specific furnace application, intended atmosphere and/or customer preference. SCR power controllers with control panel door mounted diagnostics displays are standard for bonade furnaces, with optional PLC and PC systems integration available. Heating systems are factory prewired to meet NEC and NFPA standards where applicable, and all equipment is factory tested prior to shipment.
GAS FIRING SYSTEMS
Gas fired furnaces employ either direct gas firing or radiant tube style gas firing burners to maintain the integrity of the furnace atmosphere. Sealed burner systems can be supplied as either standard tube firing or single end recuperative type based upon customer preference. Solid state flame supervision systems with panel door mounted diagnostics displays are standard for bonade furnaces, with optional PLC and PC systems integration available. Combustions systems are factory prepiped to meet FM, IRI, and NFPA standards where applicable, and all equipment is factory tested prior to shipment.
THERMAL RECIRCULATION SYSTEMS
bonade furnaces utilize alloy construction cartridge type fans for recirculation of the furnace atmospheres, promoting close tolerance temperature uniformities. Recirculation fans are located within a stainless steel plenum positioned in the top of the furnace heating chamber, integrated with the gas firing or electric heating system, to eliminate potential of direct heating of the workloads. Lateral sidewall ductwork is employed for introduction of the furnace atmosphere into the workzone beneath the workload, with recirculation and redistribution through the fan plenum inlet.
TRIPLE SEAL DOOR DESIGNS
The design of the furnace door is to provide for a triple-seal of ceramic fiber to ceramic fiber, fiber to furnace steel faceplate, and a gasketed perimeter seal around the furnace door. This triple-seal design, combined with our pneumatically operated, automatic clamping devices, create a positive pressured door seal, minimizing heat loss while maintaining atmosphere integrity. All door opening systems are designed to move the door away from the faceplate to eliminate abrasion of the refractories during operation.

CUSTOM DESIGNED AND ENGINEERED
Our in-house engineering and manufacturing allows bonade to custom design furnaces and systems to a customers process and specification requirements, rather than attempting to provide to you standard pre-design equipment, as some of our competitors would attempt to do. Follow-up technical services are available for all bonade thermal process systems.
Our ENGINEERED THERMAL SOLUTIONS will allow for flexibility in your manufacturing productivity.
