Abstract: A system for automated control of an industrial process system, comprising: a data historian storing measured process data sensed by a plurality of sensors within the industrial process system; a processor; and, memory storing a control engine as computer readable instructions that, when executed by the processor, cause the processor to: receive an artificial intelligence control setpoint for controlling an operating condition of the industrial process system; compare the artificial intelligence control setpoint to a static threshold and a dynamic threshold; and output a control signal, to manipulate the operating condition, as one of the artificial intelligence control setpoint, the static threshold, or the dynamic threshold based on a relationship of the artificial intelligence control setpoint to the static threshold or dynamic threshold.

Abstract: Emissions of NOX and/or CO are reduced at the stack by systems and methods wherein a primary fuel is thoroughly mixed with a specific range of excess combustion air. The primary fuel-air mixture is then discharged and anchored within a combustion chamber of a burner. Further, the systems and methods provide for dynamically controlling NOX content in emissions from a furnace by adjusting the flow of primary fuel and of a secondary stage fuel, and in some cases controlling the amount or placement of combustion air into the furnace.

Abstract: Systems and methods operate to infer a fuel composition in a combustion system. The fuel composition may be inferred by receiving measured operating parameters including one or more of fuel data defining fuel characteristics used in combustion within a heater of the combustion system, emissions data defining emission gasses exiting the heater, airflow data defining ambient air being supplied to the heater and airflow rate of the air within the heater. One or more relationships within the measured operating parameters may be identified that result in a list of potential fuel compositions. One of the potential fuel compositions from the list may be selected having sufficient likelihood of resulting in the measured operating parameters as an inferred fuel composition. The output the inferred fuel composition to a heater controller of the combustion system and used for automatic control thereof.

Abstract: Combustion heater control systems and methods that include dynamic safety settings. Current operating parameters of the combustion heater are sensed at a plurality of time intervals and converted into a time-varying signal. The time-varying signal is compared to a burner stability envelope indicating when a burner is likely to enter an unstable state. The unstable state may include huffing, flashback, and/or liftoff. When the burner is likely to enter an unstable state, the combustion heater is controlled to prevent the unstable state.

Abstract: Systems and methods for determining operating discrepancy a process heater. The discrepancy may be identified by solving a fired-systems model of the heater. The fired-systems model is then compared to current operating data. If the sensed current operating data is outside of the expected value(s), as defined by the fired-systems model, the systems and methods may take a remediation action to resolve the discrepancy. The discrepancy may include convection fouling identification and identification of tramp-air leaks within the process heater that are otherwise not easily detected by a human operator.

Abstract: Systems and methods iteratively solve a fired-systems model of the process heater based on fuel information, a target heat release of the plurality of burners, ambient air information, and available airflow at each of the plurality of burners to identify optimized burner air register settings to achieve a target global excess oxygen level to be sensed by the oxygen sensor. The optimized burner air register settings may be output to a heater controller of the process heater for control of the process heater.

Abstract: The present invention relates to a system and method of separating particulates from an airflow. The apparatus comprises an air inlet for directing an airflow to a fluid conduit. The fluid conduit has an outer wall curvature with a radius decreasing with azimuthal distance around the fluid conduit. The fluid conduit also has one or more openings in the outer wall through which the particulates pass when the airflow accelerates through the fluid conduit. Particulates accumulate in a particulate collector that is fixed to the fluid conduit and around the one or more openings.
