- FIGS. 1 to 5 The invention and its advantages will be better understood in the light of the following examples: (reference being made to FIGS. 1 to 5) in which:
- FIG. 1 schematically represents an assembly comprising a primary injector (21) with a concentric secondary injector (22), the secondary injector (22) surrounding G primary injector (21);
- FIG. 2 schematically represents an assembly comprising a primary injector (21) with a concentric secondary injector (22), the primary injector (21) surrounding G secondary injector (22);
- FIG. 3 schematically represents an assembly comprising a primary injector (21) with a non-concentric secondary injector (22), separated by a distance
- FIGS. 4 and 5 schematically represent two views of the assembly incorporated in a burner for injection in a combustion zone (1) of a gaseous combustion agent.
- Figures 1, 2, and 3 show a fluid inlet chamber (11).
- the primary injector (21) is fluidly connected to the chamber (1 1) by means of a primary passage (23).
- the secondary injector is fluidly connected to the chamber (1 1) by means of a secondary passage (24).
- the secondary passage (24) has an adjustable flow section.
- An adjustment system (32) makes it possible to adjust this flow section of the secondary passage (24) using a shutter (33).
- Figures 1, 2 and 3 also show a pressure detector (30) for detecting a gas pressure or a variation in gas pressure in the chamber (11) and a control system (31) connected to the pressure detector (30).
- the control system is also connected to and controls the adjustment system (32).
- FIG. 4 schematically represents an assembly comprising three primary injectors (21) each surrounded by its concentric secondary injector (22), a chamber (11).
- the primary injectors (21) are fluidly connected to the chamber (1 1) by the primary passages (23).
- the secondary injectors (22) are fluidly connected to the chamber (1 1) by the secondary passages (24).
- the secondary passage has an adjustable flow section.
- An adjustment system (32) makes it possible to adjust this flow section of the secondary passage (24) by means of a shutter (33).
- a pressure detector (30) is present for detecting a pressure or a variation in gas pressure in the chamber (1 1).
- a control system (31) is connected to the pressure detector (30). This control system is also connected to and controls the adjustment system (32).
- the burner comprising a block (40) with an inlet face (41) and an outlet face (42) opposite the inlet face, as well as additional injectors (50 ) for injecting an additional fluid into the combustion zone (1).
- the automatic adjustment by feedback system according to the present invention can advantageously be implemented in various combustion processes such as the production of glass.
- Glass furnaces mainly use air preheated to over 1000 ° C as an oxidizer. This hot air is obtained when passing through regenerators (stack of refractory bricks). The volume of oxidizer injected into the oven at this temperature level constitutes a significant amount of movement.
- burners operating with an oxygen-rich oxidant then appears to be a particularly suitable solution.
- These burners are generally installed in the openings available near the regenerators.
- Oxy-combustion i.e. combustion with an oxidizer containing at least 80% vol and preferably at least 90% vol of oxygen
- oxy flames are very disturbed by the flames, called “aero flames”, coming from regenerators operating with hot air, because of the least amount of movement of the oxy flame.
- the present invention can advantageously be used in this case by defining a predefined pressure range or a predefined pressure making it possible to ensure an automatic distribution of flow between the primary and secondary injections so as to maximize the pulse of the oxy flame whatever the total fuel flow.
- the power of an oxy-burner can be 800 kW whereas for a production increase of 8%, the power of an oxy-burner can be of 1.8 MW. It has been determined that a pressure of 300 mbarg at the distribution chamber between the two fuel injections ensures a very stable flame both at 800 kW and at 1800 kW.
- the automatic adjustment according to the invention of the distribution of fuel as a function of the gas pressure in the chamber when the power varies will thus optimize production costs, limit quality defects and optimize energy consumption.
