Systems and methods for dynamic boiler control

A non-transitory, computer-readable medium having instructions stored thereon that, when executed by one or more processors, cause a system to:

• receive flue gas data from a flue gas sensor of a boiler associated with the system;
• receive blower data associated with a blower of the boiler;
• determine, based at least in part on the blower data, a current fire status of at least two fire statuses of the boiler;
• provide one or more fire-status-specific parameters based on the current fire status of the boiler;
• compare the flue gas data to a target flue gas value;
• in response to determining that the flue gas data is indicative of a flue gas concentration that is less than the target flue gas value, execute one or more boiler operation rules using the one or more fire-status-specific parameters;
• and
• 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, wherein the adjustment is implemented via both (i) opening or closing of a fuel shutter at a speed selected from a first set of speeds, and (ii) increasing or decreasing the current blower output at a speed selected from a second set of speeds.
