Abstract
Digital sootblower control systems and methods therefor are provided in accordance with the teachings of the present invention. In the digital sootblower control systems provided within the present invention, a programmable controller is interconnected to a scanner, a display panel, sootblower drivers, sootblower signal receivers, and information input panels. The information input panels are capable of designating sootblowers within the system, sootblowing program routines to be established and sequences of program routines to be initiated. The programmable controller is provided with an executive program which is determinative of system parameters to be monitored as well as limits upon sootblowing program routines to be established. Once a sootblowing program routine has been initiated by an operator, the programmable controller issues orders to the sootblower drivers to start an initial sequence of sootblowers defined in the inititated sootblowing program routine. Thereafter, the scanner cyclically addresses all sootblowers so that the inactive or active state thereof is supplied by the sootblower signal receiver to the display panel which provides indicia as to the state of the…
