Systems and methods for dynamic boiler control are disclosed. The system can receive flue gas data from a flue gas sensor and can receive blower data associated with a blower of the boiler. The system can determine, based at least in part on the blower data, a current fire status of the boiler and can provide one or more fire-status-specific parameters based on the current fire status of the boiler. The system can compare the flue gas data to a target flue gas value, and in response to determining that the flue gas data is less than the target flue gas value, the system can execute one or more boiler operation rules using the one or more fire-status-specific parameters. The system can output instructions for adjustment of an air-fuel ratio of the boiler based on the boiler operation rules and the one or more fire-status-specific parameters.
