Abstract

The boiler is a fundamental part of almost all industries. It varies in application from low pressure to high pressure. The paper outlines the various stages of operation involved in the conversion of a manually operated boiler towards a fully operated boiler. The initial phase of the paper focuses on passing the inputs to the boiler at a required temperature, so as to maintain a particular temperature in the boiler, and shows the
temperature/pressure relationship. To achieve desired steam pressure (2Bar) at certain temperature, the Properties of Steam Table analysis is done. A proper boiler design and modelling and safety precautions are taken into consideration. Focussing on level, pressure, temperature parameters are constantly monitored using SCADA screen which is connected to the PLC.

INTRODUCTION

PLC applications are extensively used in industries to control and facilitate repetitive processes such as manufacturing cell management, fly-by-wire control, or nuclear plant systems.One of these applications is industrial automation which includes numerous automated processes. This again includes boiler automation which demands determination of certain physical parameters (viz. pressure, temperature, etc.) & utilizing these parameters to make the boiler start-stop or function in any manner we want, but automatically, without involvement of any human. Nowadays, every new industry before stepping into the production line, never givesup thinking about ways of automating it`s production process, so as to reduce it`s overallexpenditure in terms of wages, wastage of material due to inaccurate manual work and to reducethe overall time taken for production. This is where the job of PLCs come into picture. There aremany companies manufacturing PLC trainer kits. Companies like
Siemens, Allen Bradley, ABB, LG, Mitsubishi, Omron, GE Fanuc are the leading global manufacturers of PLCs, each varyingfrom the other in terms of CPU memory, number of digital and analog inputs and so on. Themain theme behind using a PLC is reduction of cost as well as complexity of incorporating hugenumber of electrical devices, easier error detection, optimization of overall production time andabove all automation
