Industrial Automation of Gas Tunnel Kiln Using Relay Logics, PLC and VFD’s

Automation is one of the most pressing issues in any sector today. Automation is affecting almost every aspect of life, from agriculture to space technology. Plant automation is a must-have for the manufacturing business in today's internationally competitive market. It refers to the system's ability to function without human involvement at all times. We are designing a control circuit for the automation of the Gas Tunnel Kiln (GTK) using relay logics and Variable Frequency Drives (VFD's) in this paper because the current doors and movement of the transfer car in and out of the kiln are being operated manually and the temperature of the kiln is very high, making manual operation unsafe. The GTK has a vestibule on the front and the rear side. The charging and discharging of the green Insulators is being automated as a whole. The first stage is to create ladder diagrams that can be realised with hardware components and then simulate them using LADSIM - PLC Simulator.
