Abstract
A closed-loop control system for intelligent soot blowing of a utility boiler is provided, including an intelligent soot blowing server, a distributed control system, a physical isolation device, a client and a heating surface soot blower group, where the intelligent soot blowing server communicates with the DCS via the physical isolation device, reads data from the DCS, and sends a soot blowing alarm signal or a soot blowing control signal to the DCS after processing the data; the client and the heating surface soot blower group establish communication links with the DCS separately; a program and a control flow of the closed-loop control system for intelligent soot blowing is developed; a time protection soot blowing flow for a heating surface of an air pre-heater is set in the control flow; a screen of the closed-loop control system for intelligent soot blowing is set up and installed in the DCS.
