Boiler Automation
Over the years the demand for high quality, greater efficiency and automated machines has increased in this globalised world. The initial phase of the process focuses on passing the inputs to the boiler at a required temperature, so as to constantly maintain a particular temperature in the boiler.
The process mainly focuses on level, pressure and flow control at the various stages of the boiler plant. Thus the temperature in the boiler is constantly monitored and brought to a constant temperature as required by the power plant.
The automation is further enhanced by constant monitoring using SCADA screen which is connected to the PLC by means of communication cable. At the automated power plant, the boiler is controlled by Variable Frequency Drive (VFD) to put in action the required processes to be carried out at the boiler.
Conventional equipment systems are prone to errors due to the involvement of humans in the data collection and processing using complicated mathematical expressions. Thus what we require is a system that collects raw data, processes it and presents it in values which can be verified and compared with the standard values.
All the values can be filled up by the introduction of the automation technique into the power plants. The automation technique involving the automatic control of all the processes which includes the monitoring and inspection needs provides for a very efficient system. The automation process helps the company having the power plant to reduce the amount of errors that occur , reduction in the human resources, increased efficiency, and most importantly very cost effective.
