Firing
1 High Velocity Short Flame Burner
2 Direct On/Off pulse firing effect.
3 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
1 Trolley - movement by geared motor with brake.
2 Door - movement by geared motor with brake, counter weighed,
3 Door Lock Unlock - innovative,Pneumatically operated instant latching unlatching for perfect sealing
Construction:
1 Strong rigid construction
2 Heat resistant grade CI castings at door and frame, bogie and furnace interface eliminates warpage.
3 Railway rails for load bearing under temperature.
4 Double sealing minimising heat losses.
Insulation :
1 High temperature high density ceramic fibre modular lining.
2 Self supporting U-fold door lining.
Recuperator :
1 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 :
1 Large furnaces handle high value materials, it is essential to install PLC for opration to avoid manual errors.
2 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 .
3 PLC monitors each & every operation during auto cycle for supply conditions, flue temperatures burner operations any deviation is automatically notified audio visualy & through SCADA
4 PLC keeps event history for the record
Control Panel :
1 Aesthetically powder coated control panel.
2 Electrical switch gears for drives, burners.
3 Status indication and control.
4 Burner sequence controller and flame failure device.
5 Programmable startup, burner, temperature controlling system.
Calibrations :
1 Thermal survey as per API 6A Standard.
2 All measuring instruments calibrated to national traceability
