  • Publication number: 20240125470
    Abstract: A method and device for monitoring combustible matter in a hot gaseous stream and generating a control signal, a controlled jet of an oxidant is injected into the gaseous stream with a lance extending between a window of a monitoring device and the flow path of the gaseous stream, the lance defining a line of sight between the window and the gaseous stream in the flow path, the combustible matter burns with the oxidant in a flame in the gaseous stream in front of the lance, one or more properties of the flame which are correlated with the concentration of combustible matter in the gaseous stream are detected by the monitoring device through the line of sight and the window and the monitoring device processes the one or more detected flame properties and generates a control signal on the basis of the one or more detected flame properties.

  • Publication number: 20230194082
    Abstract: Combined combustion and post-combustion method whereby flue gas is generated by combustion in a main combustion zone, the flue gas being evacuated from the main combustion zone and introduced into a post-combustion zone where the flue gas is subjected to post-combustion and post-combusted gas is obtained which is evacuated from the post-combustion zone, whereby a first level of one or more combustible substances in the flue gas evacuated from the main combustion zone and/or a second level of one or more combustible substances in the post-combusted gas evacuated from the post-combustion zone is/are monitored, whereby a control signal is generated on the basis of the monitored level(s) and whereby the post-combustion oxidant injection rate or the stoichiometric excess of post-combustion-oxidant with respect to post-combustion fuel is regulated in function of said control signal.

  • Patent number: 11598521
    Abstract: Process for combusting a fuel with an oxidant and burner for the implementation thereof, process wherein at least one stream of the fuel is injected through at least one first perforation, a main flow of oxidant is injected below or above the one or more streams of the fuel through at least one second perforation, an auxiliary flow of the oxidant is introduced into contact with the at least one fuel stream so as to generate an initial flame by an initial partial combustion of the fuel with the auxiliary flow of the oxidant, this initial partial combustion being completed downstream of the initial flame by means of the at least one main stream of the oxidant, the flow rate of the main flow of the oxidant or the ratio between the flow rate of the main flow of the oxidant and the flow rate of the auxiliary flow of the oxidant being adjusted depending on the emission intensity of the initial flame.

  • Publication number: 20220074592
    Abstract: An assembly for injecting a gaseous combustion agent into a combustion zone, the assembly having a chamber having an inlet, through which the agent is introduced into the assembly; at least one primary injector configured to convey a primary flow of the agent from the chamber toward the combustion zone, at least one secondary injector for conveying a secondary flow of the agent from the chamber toward the combustion zone, a pressure detector; a regulating; and a control system connected to the pressure detector and to the regulating system, the control system controlling the regulating system so that the flow section of the at least one secondary passage is regulated as a function of the pressure or of the variation in pressure detected by the pressure detector.
