Rotary furnace for degreasing metal turnings
The direct gas fired rotary furnace was
used to degrease metal turnings which were fed to it from
a conveying system.
The temperature control of the furnace was poor resulting
in either poor degreasing when it was too cold or fires and
consequent downtime when it was too hot.
A new control system
and sensors based around a Mitsubishi PLC were installed
together with new burner safety systems for the gas burner.
This resulted in much better temperature control which
allowed an increase in throughput without the fire risk.
