Industrial Gas Fired Ovens

CONSTRUCTION

A commercial Gas Fired Oven is usually of steel construction, composed of inner and outer shells of sheet steel sections, separated by 4" thick, 6 lb/ft3 density mineral made of woll insulation. The sections are built regarding minimize metal-to-metal contact between inner and outer shells and lower warmth flow from oven chamber towards the exterior surface. The structures are self-supporting, rigid, as well as sufficient strength to aid all auxiliary equipment. Interior surfaces can be created of 16 or 18 gauge aluminized steel and outer surfaces are constructed with 16 or 18 gauge aluminized steel too.

OVEN Writers &lifier Heating units

The Oven is heated by a number of gas fired writers. Writers are often situated within the combustion chamber, separated from work chamber. Typical burners capacity is 1. x 106 BTUH designed in a way the Oven shall achieve the right operating temperature in the required time. Electric heating units that might be used are situated around the walls from the Entry and Exit finishes from the Oven. Recirculation air within the Oven is heated by way of the gas fired writers within the combustion chambers and also the electric heating units around the walls. The style of the combustion chamber would be to fulfill the specs for gas fired heating.

RECIRCULATION SYSTEM

A Stove at roughly 25,000 CFM capacity for instance would discover one (1) Air Package Type Recirculation Fan with. The recirculation fan is finished with belt guard, belt drive, air flow switch, pillow block bearings, and secrets. The recirculation fans are impelled with a 5 - 50HP motor installed on a variable base.

EXHAUST SYSTEM

The Pre-heat Oven will get a number of General Purpose Exhaust Fans with 1,500 CFM capacity (each) normally. The exhaust fan is finished with belt guard, belt drive, air flow switch, pillow block bearings, and secrets. The exhaust fan is driven with a motor installed on a variable base.

SUPPLY AND RETURN PLENUMS

The Availability and Return Plenums are will include mister nozzles are constructed with 18 gauge aluminized steel which are adjustable to balance the flow. The new air is shipped within the Ovens in the supply plenum situated on the ground and it is came back with the top opening within the Combustion Chamber.

ELECTRICAL CONTROLS

One large NEMA-12 User Interface typically can be used to accommodate the controls. The panel could be connected to the Oven sidewall. A controller, switches, and showing lighting is mounted evidently from the User Interface. Additionally, the Oven has got the following controls integrated into the machine:

o Control Energy Selector switch.

o High Temperature Limit to make sure hot temperature safety.

o Temperature Controller to manage burners.

o Combustion Air Blower is integrated towards the burners like a warmth source as well as for complete combustion from the fuel gas.

o Fan Interlock: All fans are interlocked by air flow switches to avoid getting too hot from the Oven if fan is either off or inoperative.

o Power supply
