This document presents a project on 3 element control of a boiler system using a programmable logic controller (PLC), proportional-integral-derivative (PID) controller, and supervisory control and data acquisition (SCADA) interface. The proposed system aims to overcome limitations of previous control systems by automating control of parameters like temperature, pressure, and water level using various sensors connected to a PLC. The PLC is configured to control actuators based on input from sensors and PID logic. A SCADA interface is used to monitor parameters. Experimental results showed the system could effectively control water level and pressure based on defined setpoints and alarm thresholds.

23. CONCLUSION:
With the help of PLC it can be possible to overcome
drawbacks in drum level of boiler. Thus, we can securely protect
the boiler from blast. In this work, three element control using
PLC-PID and SCADA was designed and controlled. Different
sensors are used to measure the temperature, pressure and water
level. Water level can be measured with level sensors. SCADA
will be used to monitor the parameters and PLC to control the
whole operation. Delta PLC software can used to simulate the
PID & DIAVIEW software for design of drum automation
simulation.
