Post-mix burner and use of same for generating a flame curtain, the burner having a longitudinal central dividing wall () terminating in a wall head () towards the burner top (), an oxidant inlet compartment () and an oxidant outlet compartment () on a first side of the central wall (), a fuel inlet compartment () and a fuel outlet compartment on the opposite side of the central wall (); the wall head () presenting a first set of oxidant outlet passages () and a second set of fuel outlet passages () terminating respectively in first oxidant ejection openings () and second fuel ejection openings () in an ejection surface () at the burner top (), the oxidant and fuel ejection openings () each extending in the longitudinal direction along the ejection surface ().

Compact flame-curtain burner

Method and installation for treating a CO- and HO-containing flue gas generated by an industrial process unit before CCUS, whereby the flue gas evacuated from the unit is subjected to cooling to a temperature T2 between 100 and 600° C., whereby the cooled flue gas is pretreated in one or more particle removal and/or gas cleaning and/or drying stages and the temperature of the cooled flue gas is further reduced to a temperature T3<T2, before a first part of pretreated flue gas is subjected to CCUS, a second part of the pretreated flue gas being recycled at temperature T3 as a cooling agent and mixed with the flue gas during the controlled cooling thereof, partially or fully purified COfrom the CCUS may be recycled at temperature T4<T2 may be recycled as a cooling agent and mixed with the flue gas during the controlled cooling.

Flue gas treatment method and installation

Method and installation for calcining cement raw meal in a calciner whereby fuel and a calciner oxidant having an oxygen content of at least 30% vol are introduced into the calciner so as to generate either an oxidant-lean zone or a fuel-lean zone in the calciner located between the lowermost fuel inlet level and the lowermost oxidant inlet level of the calciner, between 50% and 100% by weight of the raw meal being supplied to the calciner upstream of and/or within the oxidant-lean, respectively the fuel-lean zone.

Oxy-calcination process

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.

Method and device for automatically adapting a flame to variable operating conditions

Method of operating a rotary furnace for the production of hydraulic binder so as to reduce ring formation therein, whereby the longitudinal temperature profile in the furnace is varied during furnace operation by injecting at least one fluid other than the main fuel(s), the primary oxidizer and hot air from the material cooler with at least one continuously or discontinuously varying injection parameter.

Hydraulic-binder rotary-furnace operation

Method and burner for combusting a main fuel with a main oxidizer, whereby flows of the main fuel and the main oxidizer are injected via an injector end, comprising at least one metallic injector, said injector end being positioned in the upstream section of a main passage of a refractory block and whereby multiple jets are injected into the downstream section of the main passage to increase mixing and turbulence of the flows of the main fuel and the main oxidizer.

Method and combusting fuel and burner therefor

Variable momentum burner assembly for separately injecting fuel gas and oxidant in a combustion zone, comprising at least two fuel gas canals, at least one oxidant canal and a fuel gas distributor, whereby the at least two fuel gas canals comprise an inner fuel-conducting passage forming an inner fuel gas outlet and an outer fuel-conducting passage forming an outer fuel gas outlet, said inner and said outer fuel-conducting passages being coaxially arranged; and whereby said fuel gas distributor comprises a first fuel gas chamber in fluid connexion with the inner fuel-conducting passage of the at least two fuel gas canals and a second fuel gas chamber in fluid connexion with the outer fuel-conducting passage of the at least two fuel gas canals.

Burner assembly and method of combustion

The invention relates to a method for calcination of a material in which said material is heated by contact with a heat source essentially generated by means of a flame produced with at least one flow of fuel and primary air and a flow of secondary air, the flame comprising a first combustion zone with a temperature below 1500&#xb0; C. and a second combustion zone with a temperature above 1500&#xb0; C., where at least one flow of at least one inert gas is injected into the flame at the beginning of the second combustion zone and/or at least one flow of oxygen or a gas enriched in oxygen is injected into the second combustion zone.
