A flame analytics system that may incorporate a burner, one or more sensors at the burner, a historical database connected to the one or more sensors, a model training module connected to the historical database, and a runtime algorithm module connected to the one or more sensors and the model training module. The runtime algorithm may compare realtime data from the one or more sensors and historical data from the model training module in accordance with a machine learning algorithm. The system may further incorporate a fault detection module connected to the runtime algorithm module, a fault diagnostics module connected to the fault detection module, and an enunciator connected to the fault detection module. The one or more sensors may also include having video or acoustic sensitivity of combustion in the burner.

The present invention concerns a flame detector with optical sensors situated within a housing, which is coupled to a signal collector and focuser enclosure. The enclosure includes a reflective surface or reflective surfaces generally oriented outwardly and in optical communication with the sensors through a shield window exposing the sensors; the shield window is situated between the enclosure and the housing of the flame detector. The enclosure may have a conical shape, a parabolic shape, and may include convex or concave surfaces that reflect emission signals from an emission signal source to the sensors in optical communication with the reflective surfaces. The enclosure is thus adapted to collect emission signals and narrow or focus a field of view of the sensors, thereby increasing a detection range between the flame detector and an emission signal source such as a flame source.

Methods and systems for programming and controlling a control system of a gas valve assembly. The methods and systems include programming a control system in an automated manner to establish an air-fuel ratio based at least in part on a burner firing rate. The established air-fuel ratio may be configured to facilitate meeting a combustion constituent set point of combustion constituents in the combustion exhaust. The methods and systems include controlling operation of a combustion appliance based on closed-loop control techniques and utilizing feedback from a sensor measuring combustion constituents in exhaust from a combustion chamber in the combustion appliance. The combustion constituents on which control of the combustion appliance may be determined include oxygen and/or carbon dioxide.

A method and an assembly for controlling an internal combustion engine having multiple burners is provided. Combustion measurement data is collected in a burner-specific manner for each burner and assigned to a burner identification identifying the respective burner. Performance measurement data of the internal combustion engine is also collected and used to determine a performance value. A machine learning model is trained by means of the combustion measurement data, the associated burner identifications and the performance measurement data, to generate burner-specific control data which optimizes the performance value when the burners are actuated in a burner-specific manner using the control data. The control data generated by the trained machine learning model is output for the burner-specific actuation of the burners.

A modulating gas valve assembly includes a modulating gas valve to variably control a flow of gas through the gas valve assembly and a control circuit. The control circuit includes a valve memory storing a calibration table for the modulating gas valve, and a controller communicatively coupled to the peripheral component. The calibration table includes a plurality of control settings for the modulating gas valve, each control setting being associated with a different gas flow rate. The controller is programmed to receive a command to open the gas valve, and to control the gas valve to a target control setting in the calibration table adjusted in accordance with a valve offset.

A sensitivity parameter storing portion stores, as known sensitivity parameters owned by a flame sensor, reference received light quantity, reference pulse width, probability of regular discharge, and probabilities of non-regular discharge in advance. The discharge probability is calculated based on the number of drive pulses applied to the flame sensor and the number of discharges determined to have occurred in the flame sensor having received the drive pulses. The calculated discharge probability and the known sensitivity parameters are used to calculate the received light quantity per unit time received by the flame sensor.
