In the proposed system the previous papers disadvantages are overcome by using PLC Boilers have many serious injuries and destruction of property. It is critical fo

2、r the safe operation of the boiler and the steam turbine. Too low a level may overheat boiler tubes and damage them. Too high a level may interfere with separating moisture from steam and transfers moisture into the turbine, which reduces the boiler efficiency. Various controlling mechanism are used

3、 to control the boiler system so that it works properly, many control strategies have been applied to it. In order to automate a power plant and minimize human intervention, there is a need to develop a Boiler Automation system. It is achieved by using Programmable Logic Controller & Supervisory Con

4、trol and Data Acquisition system that helps to reduce the errors caused by humans and avoids the catastrophic failure. IV.BOILER AUTOMATION USING PLC AND SCADA In order to automate a power plant and minimize human intervention, there is a need to develop a PLC &SCADA system that helps to reduce the errors caused by humans. PLC and SCADA interfaced through communication cables. SCADA is used to monitor the boiler temperature, pressure and water level using different sensors and the corresponding
