Definitions

  • the present invention relates to a burner assembly with enhanced flexibility and in particular such a dual-fuel burner and/or a burner with staged combustion.
  • burners and notably burners with staged combustion, for the heating of a load in a furnace, such as a melting furnace.
  • the maintenance of a burner usually includes the inspection of the state of the injectors or fuel rods, their cleaning or their replacement.
  • the result of the foregoing is that, because the maintenance of a burner causes it to be taken out of service, the operation of maintaining the burner or burners of an industrial furnace has a temporary negative impact on the performance of the furnace and/or the quality of the product. Moreover, the maintenance of the burner or burners is essential for the safety of the furnace and its longer-term productivity.
  • Switching a burner from a first fuel to a second fuel usually requires the fuel injectors to be replaced and therefore normally the burner to be taken out of service. This operation may take several hours in the case of cold reagents, but it may be spread over several days in the case of preheated reagents.
  • the present invention proposes a burner assembly which makes it possible to maintain the fuel rods without having to stop the burner, and even without having to reduce the power of the burner.
  • the present invention also proposes a burner assembly which allows the switch from a first fuel to a second fuel or to a combination of several fuels and vice versa without having to stop the burner, and even without having to reduce the power of the burner.
  • the present invention relates more particularly to a burner assembly comprising:
  • the burner unit has an inlet face and an outlet face, at least one oxidant passageway between the inlet face and the outlet face and at least one fuel-rod passageway between the inlet face and the outlet face.
  • Said burner unit is such that m fuel rods can be simultaneously mounted in the burner unit through the at least one fuel-rod passageway, where m>1.
  • Each of the first-fuel rods is capable of being mounted in the or in one of the fuel-rod passageways, and of being removed from said fuel-rod passageway via the inlet face of the burner unit.
  • it is specifically important to be able to insert and remove the rods without the rods, the burner unit and in particular the fuel-rod passageway(s) being damaged thereby.
  • the oxidant-supply device is capable of transporting a flow of oxidant from a source of oxidant to the burner unit for its injection through the at least one oxidant passageway into a combustion zone situated downstream of the outlet face.
  • the first fuel-supply device is capable of transporting a flow of a first fuel from a first-fuel source to the burner unit for its injection into the combustion zone through one or the fuel-rod passageway(s).
  • This first fuel-supply device comprises a first supply line, a first flow meter, a first distributor and n first flexible lines connecting the first distributor to the n first-fuel rods.
  • the first supply line is more particularly capable of transporting said flow of the first fuel from the first-fuel source to the first distributor.
  • the first flow meter is capable of regulating the rate of flow of the first fuel from the first-fuel source to the first distributor and the first distributor is capable of dividing the flow of first fuel into n subsidiary flows on the n first flexible lines.
  • the flexible lines make it much easier to insert the fuel rods into the fuel-rod passageway(s) and to remove the fuel rods from said passageways.
  • the burner assembly according to the present invention is characterized notably in that the first fuel supply device comprises one or more valves making it possible to close or open the n first flexible lines one by one so that, when x of the n first flexible lines are closed by said one or more valves, where 1 ⁇ x ⁇ n ⁇ 1, the first distributor divides the flow of first fuel into the n ⁇ x first flexible lines which are open for its injection into the combustion zone by the first-fuel rod or rods connected to said first open flexible lines.
  • the burner assembly according to the invention therefore makes it possible, during the maintenance of one or, if necessary, several of its first-fuel rods, to keep the burner assembly in operation and to do so without having to reduce the level of the power supplied by said burner assembly to the combustion zone. In this manner, the effect of the maintenance of the first-fuel rods on the thermal profile in the furnace, and therefore of the productivity of the furnace and/or the quality of the product originating from the furnace, is greatly reduced.
  • Each first flexible line may, for example, be furnished with a valve making it possible to open and close this flexible line.
  • the first fuel-supply device may also comprise a valve which makes it possible to close and open selectively one or more of the first flexible lines.
  • the burner assembly may comprise a central control unit for the opening and the closure of the first flexible lines by the valve(s) of the first fuel-supply device and/or means for the manual operation of this or these valves.
  • a flexible line is closed when it does not allow a flow of fuel to pass and that a flexible line is open when it allows a fuel flow to pass through the flexible line.
  • the first fuel may in particular be a gaseous fuel (such as natural gas) or a liquid fuel, such as fuel oil.
  • the number n of first-fuel rods is equal to the number m of fuel-rod passageways in the burner unit.
  • the number n of first-fuel rods is equal to the number m of fuel-rod passageways+1.
  • this embodiment makes it possible, when one of the first-fuel rods is taken out of service for its maintenance by the closure of the corresponding first flexible line, to replace in the burner unit the rod under maintenance with the m+1 st first-fuel rod and to open the first flexible line that corresponds to this m+1 st rod so as to be able to operate the whole burner with m first-fuel rods during the maintenance of one of the first-fuel rods.
  • the effect of the maintenance of the first-fuel rods on the thermal profile in the furnace, and therefore on the productivity of the furnace and/or the quality of the product coming from the furnace is again more clearly reduced, or even eliminated.
  • a source of fuel called a reserve source, linked by means of a reserve-fuel supply device to a reserve-fuel rod so as to be able, for a burner assembly having, in normal operation, an injection of first fuel into the combustion zone by means of m first-fuel rods, when one of the m first-fuel rods is taken out of service for its maintenance by the closure of the corresponding first flexible line, to replace in the burner unit the first fuel-rod under maintenance with this reserve-fuel rod and thus be able to operate the burner assembly with m ⁇ 1 first-fuel rods and the reserve-fuel rod during the maintenance of one of the first-fuel rods.
  • a reserve source linked by means of a reserve-fuel supply device to a reserve-fuel rod so as to be able, for a burner assembly having, in normal operation, an injection of first fuel into the combustion zone by means of m first-fuel rods, when one of the m first-fuel rods is taken out of service for its maintenance by the closure of the corresponding first flexible line, to replace in the burner unit
  • the reserve fuel may also be a gaseous or liquid fuel.
  • the reserve fuel is advantageously a liquid fuel, notably because of the ease of storage and transport of such a fuel.
  • the reserve fuel may be of the same type (gaseous, liquid, etc.) as the first fuel or of a different type.
  • the composition of the reserve fuel may match or be different from the composition of the first fuel.
  • the present invention also relates to a burner assembly as described above and which also comprises:
  • Each of said second-fuel rods is able to be mounted in the or in one of the fuel-rod passageways and to be removed from said fuel-rod passageway via the inlet face, as already indicated above for the first-fuel rods.
  • the second fuel device is capable of transporting a flow of a second-fuel from a second one or fuel source to the burner unit for its injection into the combustion zone through one or the fuel passageway(s).
  • the second fuel-supply device comprises a second supply line, a second flow meter, a second distributor and p second flexible lines connecting the second distributor to the p second-fuel rods.
  • the second supply line is capable of transporting the flow of the second fuel from the second-fuel source to the second distributor.
  • the second flow meter is capable of regulating the rate of flow of the second-fuel from the second-fuel source to the second distributor.
  • the second distributor is capable of dividing the flow of second fuel into p subsidiary flows on the p second flexible lines.
  • the second fuel-supply device comprises one or more valves making it possible to close and open the p second flexible lines one by one so that, when y of the p second flexible lines are closed by said one or more valves, where 1 ⁇ y ⁇ p ⁇ 1, the second distributor divides the flow of second fuel over the p ⁇ y second flexible line(s) which is/are open for its injection into the combustion zone by the second-fuel rod or rods connected to said second open flexible line(s).
  • Each second flexible line can, for example, be furnished with a valve making it possible to open and to close this flexible line.
  • the second fuel-supply device may also comprise a valve which makes it possible to close and to open selectively one or more of the second flexible lines.
  • the burner assembly may comprise a central control unit for opening and closing the second flexible lines by one or the valves of the second fuel-supply device and/or means for the manual operation of this or these valves.
  • the second fuel may in particular be a gaseous fuel or a liquid fuel.
  • the second fuel may be of the same type (gaseous, liquid, etc.) as the first fuel, but in practice most frequently of a different type.
  • the reserve fuel When use is made of a reserve fuel, the reserve fuel may also be a gaseous or liquid fuel.
  • the reserve fuel is advantageously a liquid fuel, such as fuel oil, notably because of the ease of storage and of transporting such a fuel.
  • the number n first-fuel rods may be equal to the number p second-fuel rods.
  • the number p of second-fuel rods may be equal to the number m of fuel-rod passageways of the burner unit.
  • the number p of second-fuel rods may be equal to the number m+1 of fuel-rod passageways.
  • the burner assembly according to the invention may be used in air combustion, but is particularly useful for applications in oxycombustion.
  • the invention therefore relates in particular to a burner assembly in which the source of oxidant is a source of oxidant having an oxygen content of at least 80% vol, preferably of at least 90% vol.
  • the burner assembly according to the invention is notably advantageous for staged combustion.
  • the method of staged combustion of fuels consists in dividing the quantity of oxidant necessary for the total combustion of the fuel into at least two flows of oxidant inserted into the combustion zone at different distances from the injection of the flow or flows of fuel into this combustion zone. Therefore, at least one first flow of oxidant is injected very close to or together with the flow or flows of fuel.
  • the oxidant injected by this or these flows of injected oxidant closest to or with the flow or flows of fuel is called primary oxidant.
  • the or the other flow(s) of oxidant are injected into the combustion zone at a greater distance from the fuel than the primary oxidant.
  • the oxidant thus injected makes it possible to achieve the combustion of the fuel that has not reacted with the primary oxidant.
  • the oxidant injected by this or these latter flows is called secondary oxidant.
  • Document WO 02/081967 describes a method making it possible to apply this type of staged combustion method.
  • the oxidant is separated into three distinct flows which are injected at different distances from the injection point of the fuel and at different speeds. Therefore, a first jet of oxidant is injected at a high speed at the center of the jet of fuel. Then, a second jet of oxidant is injected at a lower speed at a first distance from the jet of fuel. Finally, a third jet of oxidant is injected at a second distance from the jet of fuel, this second distance being greater than the first distance.
  • the invention therefore also relates to a burner assembly in which the oxidant-supply device is capable of transporting several oxidant flows from a source of oxidant to the burner unit for its injection through the at least one oxidant passageway into the combustion zone, at least one of said oxidant flows being a secondary oxidant flow injected into the combustion zone through an oxidant passageway situated at a distance ds>0 from the fuel-rod passageway(s) and at least one of said oxidant flows being a primary oxidant flow injected into the combustion zone through the or one of the fuel rod passageways or through an oxidant passageway situated at a distance dp from the fuel-rod passageway(s), where 0 ⁇ dp ⁇ ds.
  • At least one of the oxidant flows is a primary oxidant flow injected through the or one of the fuel-rod passageways around one or the fuel rod(s).
  • the inventors have in particular proposed, in application EP-A-1995543, heat exchangers making it possible to heat the oxygen satisfactorily.
  • the oxidant-supply device comprises means for the heating of the at least one secondary oxidant flow to a temperature of at least 100° C. upstream of the burner unit, said oxidant-supply device comprising no means for the heating of the at least one primary oxidant flow.
  • Said primary oxidant which is injected into the combustion zone through the or one of the oxidant-rod passageway(s) or through one or the oxidant passageway(s) situated at a distance dp from the fuel-rod passageway(s) is therefore not heated or preheated to a temperature of 100° C. or more at the inlet of the burner unit.
  • the secondary oxidant is preheated to a temperature at the inlet of the burner unit of between 100° C. and 650° C., preferably between 100° C. and 600° C., and again preferably between 350° C. and 550° C.
  • This embodiment makes it possible to improve energy efficiency through the use of a preheated oxidant for the secondary oxidant, while retaining the enhanced flexibility of the burner according to the invention, notably with respect to the maintenance of the fuel rods and/or the switch from a first fuel to a second fuel or to a combination of several fuels, through the use of a non-preheated oxidant for the primary oxidant.
  • the non-preheated primary oxidant provides only a very small fraction of all the oxidant necessary for the total combustion of the fuel. This fraction is usefully less than 10% of all the oxidant.
  • this proportion ranges between 1.5 and 7% of all the oxidant necessary to ensure the complete combustion of the fuel.
  • the (primary) oxidant is in the essential ambient temperature conditions that prevail on its path taking it to the furnace. On passing the refractory walls of the furnace, its temperature necessarily rises.
  • the temperature of the non-(pre)heated oxidant is preferably the ambient temperature and must not exceed one hundred degrees Celsius, the temperature in the vicinity of the furnace nevertheless being substantially higher than that of the atmosphere at a distance from the furnace.
  • the primary oxidant and the secondary oxidant may have an identical or different composition.
  • the primary oxidant and the secondary oxidant have one and the same composition, they can be provided by one and the same source of oxidant, such as, for example, a unit for separating gases from the air, the secondary oxidant passing through, upstream of the burner unit, means for the preheating of said secondary oxidant, such as notably heat exchangers, while the primary oxidant does not pass through any means for preheating it upstream of the burner unit.
  • the burner unit may consist of a single brick.
  • the burner unit may also advantageously consist of a set of several bricks, typically fire bricks. When the burner unit consists of several bricks, said bricks may be spaced out, notably when the burner assembly is mounted in a wall of a furnace.
  • the use of a burner unit which consists of several bricks allows in particular a staging of the combustion that is more spaced out, that is to say the injection of at least one jet of secondary oxidant at a greater distance from the injection(s) of fuel.
  • a burner unit which consists of several bricks may also allow a more spaced injection of different jets of fuel.
  • the invention relates notably to a burner assembly in which the burner unit is mounted in a wall of a furnace, the combustion zone downstream of the outlet face being situated inside the furnace.
  • the invention also relates to a furnace comprising such a burner assembly.
  • the invention also relates to the use of one or more of these burner assemblies for carrying out the combustion of oxidant and fuel in a combustion zone and in particular in such a combustion zone inside a furnace, and any combustion method by means of a burner assembly or of a furnace according to the invention.
