METHOD OF ASSESSMENT OF THE QUALITY OF THE BURN OF THE GASES IN THE FLARE AND ADJUSTMENT TO THE VAPOR FLOW RATE IN A CONTINUOUS AND CONSTANT WAY
The present invention presents a method of assessing the quality of the burning of the gases in the flare and adjusting the vapor flow rate in a continuous way and with flexibility to integrate with different instrumentation topologies of the flare control system. The state of the flare flame is identified from an image set of the flame, classifying it into one of four: flame with excess vapor, optimized flame, flame with soot or images with insufficient information to classify them as one of the previous states of the flare flame. In addition, it is further able to quantify the height of the flame. The invention comprises the following components: flare, camera, image stream manager, edge computer, data historian, alert manager, information visualization panels, distributed digital control system, DDCS, and cloud storage and computing.

SYSTEM AND PROCESS FOR HYDROGEN COMBUSTION
The invention relates to a system and process for hydrogen combustion for industrial or steam generation applications, and more particularly to a hydrogen combustion burner or retrofit kit combustion system and process using a primary pure hydrogen fuel source. The burner or retrofit kit combustion system and process may also use one or more secondary fuels, such as natural gas, methane, propane, or the like, to reduce emissions of CO.sub.2.
