Abstract
The most important unit in a process industry or power station is a boiler. In thermal power plant a three element control of boiler drum includes three process variables such as drum level, feed water flow and steam flow to control boiler drum. Water interface exist in boiler drum and the level of water in the boiler drum is very difficult to maintain. If the water level becomes too low the boiler can run dry, resulting in mechanical damage of the drum and boiler piping. If the level becomes too high, water can be carried over into steam pipe work and causes damage in downstream equipment. The data from entire plant is received and logged in DCS system for experimental analysis. The data logging system of the plant DCS monitors process variables and multi loop control in a plant and measures and record the process variable manipulated variable control signal etc., of a different control process. The data logging requires huge memory forrecording different variables of the plant. The measured variables stored in cloud and used in the process with the IOT technology and
hence huge memory occupation in DCS is reduced. In this project IOT concept has been implemented in the boiler drum level control in thermal power plant and variables which are monitored, recorded and controlled by using IOT.
