| Abstract: | A modification design was conducted of the control system of a thermal power plant boiler air dryer through the addition of a OMRON PLC controller. The on site commissioning tests show that the PLC based control system has promoted a safe and reliable operation with powerful functions and a high flexibility in conducting operation changes. As a result, all design targets have been attained. |
