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
