Control and analysis of crucial parameters for an automatic boiler unit in a chemical industry

Abstract

A boiler plays a significant role in a processing industry, particularly in chemical industry. It requires proper adoption of control techniques for supplying accurate temperature, pressure, steam, and water flow to produce chemicals. An uncontrolled boiler can shut down the whole process. Therefore it requires a continuous monitoring system for avoiding such shutdown. In the past few decades, relay logic, embedded or process card systems were used for controlling the boiler system. In the conventional system, the controlling scheme was also complex for troubleshooting because process cards are used only once. In order to overcome this type of problem Supervisory Control and Data Acquisition (SCADA) and Programmable Logic Controller (PLC) system helps to collect data and information about the flow of boiler from various sensors. In this paper, SCADA and PLC assist in controlling crucial parameters using Proportional Integral Derivative (PID) control. PID controller used in this paper is programmed according to the boiler operation's need, and the data can be stored and analyzed using the SCADA system. The results in this paper help the industrial personnel for boiler automation, allowing the plant operator to observe the crucial parameters for increasing boiler efficiency and reducing the financial losses.
