Solution. Each of the four boilers has two power settings. Each power setting is assigned to PLC. The master thermostat is connected to PLC input. The thermostat is used to set the temperature at which the boiler is to be switched on and off. Say, If the temperature falls below 75°C, the first power setting of boiler 1 is activated for heating.

Control of Boiler Operation using PLC – SCADA K. Gowri Shankar Abstract––This paper outlines the various stages of operation involved in the conversion of a manually operated boiler towards a fully automated boiler. Over the years the demand for high quality, greater efficiency and automated machines has increased in this globalised world.

A single element control system is one with just one control input, a two element control system is one with two control inputs, etc.. A three-element boiler water level control system is one which typically uses the measured water level, the steam flowrate from the boiler, and the water flowrate into the boiler to regulate the flow of water into the boiler.

Among the boiler’s main control loops is the combustion control: variable frequency drives on primary and secondary air fans adjust the airflow based on the air/bagasse curve, in order to guarantee the required excess air under different operating regimes. The air/bagasse curve operates according to a curve determined by the manufacturer.

Complex boiler control systems may involve multiple digital control systems (e.g. DCS, PLC, or computer controlled smart instruments) linked together by a communication data bus. The communication data bus passes significant data between the digital control systems in a serial format. There are numerous bus architectures available.

The Control Panel is fully automated and continually monitored via a Programmable Logic Controller. The air flows and fuel feed rates are constantly and automatically adjusted by way of variable frequency drives to ensure a hot water or warm air temperature that is maintained within 3 to 5 degrees of the desired set point.
