Auto cycle control

• Ramp, Soak, Cool ..... 8 Steps Profile
• 10, 20 Profile Memory
• Multi Input Multi Output (MIMO)
• PID Controlling Action.
• Micro processor based programable controller.
• one burner, one thermocouple forms one pair as zone, thus multi zone control
• Digital display for time temprature graph online with USB pendrive for data storage, Wired lan PC connectivity for real time graph printing

Firing

• High Velocity Short Flame Burner
• Direct On/Off pulse firing effect.
• Smokeless perfect combustion
• The furnaces are calibrated for uniformity as per API 6A Standard ( The Temperature Difference Between Highest & Lowest Points at Stabilised Conditions should not be more than 13ºC.)

Mechanization

• Trolley - movement by geared motor with brake.
• Door - movement by geared motor with brake, counter weighed,
• Door Lock Unlock - innovative,Pneumatically operated instant latching unlatching for perfect sealing

Construction

• Strong rigid construction
• Heat resistant grade CI castings at door and frame, bogie and furnace interface eliminates warpage.
• Railway rails for load bearing under temperature.
• Double sealing minimising heat losses.

Insulation

• High temperature high density ceramic fibre modular lining.
• Self supporting U-fold door lining.

Recuperator

All fuel fired furnaces are equiped with recuperator to recover the heat from flue gases by preheating combustion air. By thumb rule a rise of 150 degree C in combustion air 7.5% heat is recovered.

PLC control

• Large furnaces handle high value materials, it is essential to install PLC for opration to avoid manual errors.
• PLC checks each & every operation prior to loading of materials called booting to ensure air/gas/power etc. are within the specifications & all the sensors are in working condition
• PLC monitors each & every operation during auto cycle for supply conditions, flue temperatures burner operations any deviation is automatically notified audio visualy & through SCADA
• PLC keeps event history for the record

Control Panel

• Aesthetically powder coated control panel.
• Electrical switch gears for drives, burners.
• Status indication and control.
• Burner sequence controller and flame failure device.
• Programmable startup, burner, temperature controlling system.

Calibrations

• Thermal survey as per API 6A Standard.
• All measuring instruments calibrated to national traceability
