Description

Apparatus and method for feeding regenerative fuel into a radiant boiler casing region in a gasification reactor

The present invention relates to a device for feeding a regenerative fuel into a zone of a radiant boiler casing in a gasification reactor, the gasification reactor consisting of a reaction space in which the burner is located in the reaction space and a cooling space (wherein The cooling space is provided with a radiant boiler casing for cooling and solidifying the liquid slag, wherein according to the invention, the cooling space portion of the positioning radiant boiler casing will be equipped with a burner introduced into the cooling space via the radiant boiler casing, allowing regeneration The fuel is introduced into the cooling space tangentially along the cooling space closed container. In this way, even in the cooling space for vaporizing the regenerative fuel, the heat of the hot syngas can be utilized more effectively. The invention also relates to a method of introducing regenerative fuel into a cooling space of a coal gasification reactor via a radiant boiler casing along the tangential direction of the reactor wall, and the use of syngas produced by the process.

In most embodiments, the coal gasification reactor is collected from the reaction space (where the synthesis gas is cooled by mixing it with the external medium of the cooler) and a slag collection tank (which is filled with water and then cooled to the slag for subsequent collection into the slag collection) In the tank) composition. The reaction space contains burners for introducing a mixture of a carbonaceous fuel and an oxygen-containing gas to produce a syngas in the gas stream gasification reaction.

In most embodiments, the cooling space extends directly vertically below the reaction space such that the syngas containing liquefied slag and ash initially reaches the cooling space along with the ash and slag. In the cooling space, hot syngas and cold The external medium is blended to cool the hot syngas and to discharge most of the ash and slag. The entire unit is suspended in a pressure-resistant closed container to help perform the high pressure and high temperature of the reaction.

The discharged slag and ash are transferred from the cooling space to a slag collecting tank located below the cooling space. In most embodiments, the slag collection tank is also used to collect slag water. In the slag collection tank, the slag water is disposed of from the reaction vessel via a pressure gate. Syngas is supplied via a lateral discharge connector for further processing and use. The actual coal gasification reaction typically occurs at temperatures in excess of 1400 ° C to 1500 ° C and pressures from 0.5 MPa to 8 MPa. After leaving the cooling space, the syngas has a temperature of about 900 ° C and after it is mixed with the cooler external medium, it still has a temperature between 200 ° C and 300 ° C. This syngas is withdrawn from the closed vessel by means of a reactor at this temperature.

DE 10 2008 012 734 A1 describes a method and a device for recovering synthesis gas produced by a coal gasification reaction according to the prior art, wherein the synthesis gas produced is produced in a first reactor space at the top of the reactor, the input material being at the first Feeding in the top region of the reactor space, and liquid slag is deposited on the sidewall of the first reactor space (the liquid slag is free flowing, and the slag surface is not hardened), and the bottom of the first reactor space Positioning an opening having a drip down edge from which the recovered syngas is moved downward and the liquid slag flowing downward can be dripped, and the second space designed as a cooling space is connected to the opening a bottom portion, and the second space is limited by a water film in which the third space is connected to the bottom of the second space, in which water is fed into the syngas Cooling occurs and a water bath designed as a slag connection tank is connected to the bottom of the third space, and at the bottom or side of the third space (but above the water bath), the cooled and produced syngas is drawn from the pressure vessel. The second space below the reaction space is designed as a cooling space and contains a laterally restrictive water film to prevent deposition.

Since my manpower map obtains syngas which is as free of slag and ash as possible, there is a specific example of a coal gasification reactor equipped with a so-called radiant boiler casing for the cooling space. These radiant boiler casings act as cooling plates and are positioned on the side walls of the gasification reactor. At the same time, the reaction vessel is protected by this method. The syngas flowing out of the reaction space has an angular momentum such that it contacts the cooler radiating boiler casing. During this process, the slag solidifies and falls into the slag collection tank due to gravity or due to gas flow.

DE 10 2005 041 930 A1 describes a method for gasifying a solid fuel in a sputum stream with a solid fuel by means of partial oxidation with a free oxygen-containing oxidant, wherein the pulverized coal is fed into a pneumatic metering system and the pulverized coal reaches at least via the sump a pressure gate, fed to the metering vessel after loading the condensate-free gas, introducing an inert gas at the bottom of the metering vessel to form a fluidized bed, the fluidized bed reaching the burner of the reactor via the transfer conduit, The pulverized coal fed into the reactor via the transfer line is partially oxidized together with the oxidant containing free oxygen in a reaction space having a cooling curtain, where the fuel ash is melted and transferred to the quenching via the discharge device together with the hot gasification gas The quenching chamber is cooled, and the quenched steam saturated raw material gas is subjected to raw material gas washing or mechanical dust removal to remove the entrained particles. One or several nozzle rings are positioned in the quench, by means of which nozzles are injected The quench water is required, wherein the nozzle tip is flush with the inner wear shell, which is made of a metal ring and is disposed on the reactor pressure shell to protect the reactor pressure shell.

DE 10 2005 041 931 A1 describes a process for the gasification of a solid fuel in a stream of hydrazine by partial oxidation with an oxidant containing free oxygen, which process consists of the following process steps: pneumatically metering pulverized coal in a reactor space with cooling a gasification reaction, partial quenching, cooling, raw material gas washing and partial condensation in the reactor of the profile, wherein the pulverized coal reaches the at least one pressure gate via the storage tank, and is fed into the measuring container after loading the gas without condensate, An inert gas is introduced at the bottom of the metering vessel to form a fluidized bed that reaches the burner of the reactor via a transfer conduit, and wherein the pulverized coal fed into the reactor via the transfer conduit is combined with an oxidant containing free oxygen Partial oxidation is carried out in a reaction space having a cooling curtain where the fly ash is melted and transferred together with the hot combustion gases via a discharge device to the quenching chamber of the quencher for partial quenching and partial quenching The feed gas is cooled in a waste heat boiler and subsequently cleaned and further processed.

In one embodiment of the invention, the quench space is directed to a waste heat boiler in which a conduit for generating steam is positioned and a lower portion of which is positioned to remove the feed gas and slag using a water bath. In this way, the heat of the waste heat boiler can be used to generate steam.

Many specific examples introduce syngas into a cooling space equipped with a radiant boiler casing, wherein the radiant boiler casing is composed of an internal wear shell (which is made of metal to protect the reactor pressure shell) or is piped (water The The pipeline is guided to produce steam). Both specific examples have the following objectives: no direct introduction of hot syngas into the cooling space, or directing of the hot syngas directly towards the radiant boiler casing of the closed vessel, but cooling, so that the slag is curable and discharged from the syngas .

It is sometimes possible to direct the hot syngas containing slag to the cooling slag (also known as the "bulkhead") provided for this purpose, wherein the geometry of the cooling plates along the cooling space and the vertical extension of the entire reactor The central axis is tapered concentrically. These cooling plates can also be composed of pipes. The latter should be parallel to the direction of the gas flow to improve cooling.

In a typical embodiment of the invention, the syngas has been suitably provided with angular momentum in the reactor so that the latter is not introduced directly into the cooling space, but rather has been directed towards the cooling plate in the cooling space with a small angular momentum. . The reactor itself has a funnel shaped outlet which increases the gas velocity and thus enhances the direction of the hot syngas towards the cooling plate. The actual walls positioned around the cooling plates are often equipped with pipes that protect the walls from the high temperatures of the syngas. The inlet nozzle for the external medium is positioned behind the cooling plate or baffle in the direction of the air flow.

This method has the disadvantage that the sensible heat of the syngas leaving the reactor is still unused. The syngas leaves the reactor at a temperature in excess of 1500 ° C and is between 200 ° C and 300 ° C after being cooled by supply of a cooling gaseous, vapor or liquid external medium. In this way, the heat of the syngas is lost without being used.

Therefore, it would be advantageous to use the heat of the syngas positioned between the reactor outlet and the radiant boiler casing for the chemical process, where cooling space should be considered. The specific residence time required for this chemical process. Therefore, there is a problem that the following method can be used: it directly uses the syngas or sensible heat of the syngas after the reactor outlet to ensure subsequent residence time in the cooling space, and still contributes to the cooling space. The radiant boiler casing and an external medium are supplied in the direction of the gas flow behind the radiant boiler casing to cool the syngas.

The present invention solves this problem by using a device in which the burner is positioned at a certain angle in the cooling space along the tangential direction of the reactor wall, whereby the injected fuel is subjected to angular momentum guided around the central axis of the cooling space for injection. The residence time of the material in the cooling space increases, and thus the chemical reaction is promoted with the remaining heat of the syngas.

The burner can inject regenerative fuel at an angle in the direction of the gas flow or in the direction of the reverse gas flow. However, according to the invention, the tangential direction must be followed, wherein the tangential direction refers to the chamfer, which is formed on the opposite side of the cooling space wall in the horizontal cross section of the cooling space.

At the same time, the burner must be guided through the closed vessel wall and the radiant boiler casing. Often, this requires a high design cost because the radiant boiler casing often contains pipes or thick-walled metal curtains. A common design for implementing this burner configuration is a "tube-web-tube" design.

The regenerative feedstock is preferably injected into the cooling space in the form of an additional fuel. The regenerable feedstock has the property of reacting with the syngas and not increasing the temperature substantially during the reaction. Through the tangential injection of regenerative fuel, the residence time in the cooling space is increased to facilitate the reaction of the regenerative fuel with the still hoter syngas. Syngas temperature is often further reduced with the addition of regenerative materials low. The regenerative fuel reacts with the syngas component and consumes heat. Additional syngas is produced during the reaction.

The economic efficiency of the coal gasification process can be substantially improved via the apparatus according to the invention. Since the regenerative feedstock only transfers a small amount of ash in the gasification process, the radiant boiler casing is loaded with substantially less ash and slag by the method according to the invention. Finally, the radiant boiler casing is exposed to a significantly lower heat load by subsequent introduction of regenerative fuel.

In particular, a device for feeding a regenerative fuel into a zone of a radiant boiler casing of a coal gasification reactor is proposed, comprising: a reaction space suitable for use with an oxygen-containing gas or a vapor containing water and oxygen A reaction occurs to vaporize the solid carbonaceous fuel, and is equipped with a burner, a second space, which is designed as a cooling space, and which is disposed below the reaction space along the gas flow direction, wherein the cooling space is equipped with a gas state and a vapor state. And a feeding device of the liquid cooling medium, wherein: the cooling space is equipped with at least one extension of the airflow direction with an annular radiation boiler casing disposed on the inner wall of the cooling space, and is characterized by: ● Configuring cooling of the radiation boiler casing The annular portion of the space is equipped with burners that are introduced into the cooling space via a radiant boiler casing through which regenerative fuel can be introduced into the cooling space. The burner is angled at a tangential direction along the reactor wall. Configured in the cooling space.

The design cost for the increase in the feed is thus determined by the type of radiant boiler casing. In order to carry out the invention, it is only necessary to closely guide at least one burner via a hermetic radiation boiler casing medium. In one embodiment of the invention, the conduit is disposed within the cooling space, wherein the cooling medium can flow through the conduit in the direction of the gas flow. The burner must therefore be introduced into the cooling space between the pipes or via pipes via closed containers. In the manufacture of gasification reactors, the design of the radiant boiler casing is sometimes quite different, so that the design cost of the burner configuration is determined by the design of the radiant boiler casing.

In another embodiment of the invention, a conduit of a particular length across the cooling space covers the entire interior perimeter of the cooling space, wherein the cooling medium can flow through the conduit in the direction of the gas flow. In this case, the burner must be guided to a specific location via a pipe in each case. This can be achieved with a pipe collar, however, it is implemented in an advantageous embodiment using a so-called "pipe-net-pipe" design. EP 0840053 B1 teaches a typical example of a "pipe-net-pipe" design for preventing undesired interruption of water flow through the pipe in the case of burner assembly.

In another embodiment of the invention, the annular wall is positioned between the cooling space wall and the conduit as a radiant boiler casing. Therefore, the mechanical load of the closed vessel is kept low during the cooling of the syngas containing the slag. In another embodiment of the present invention, other ducts are disposed inside the cooling space through which the cooling medium can flow in the direction of the airflow, and the ducts are arranged in parallel by concentric directions along the geometric central axis of the cooling space. To configure. These pipes preferably surround the cooling space with a specific length across the cooling space The entire inner perimeter of the pipe combination configuration wherein the cooling medium can flow through all of the pipes in the direction of the gas flow. The arrangement of the tubes that are flush with the geometric center axis of the cooling space improves the cooling of the syngas and extends the residence time in the cooling space. The concentric configuration of these pipes is also known as the "baffle." In a simple embodiment, such "baffles" can also be implemented as a plate. This configuration typically does not extend to the center of the longitudinal axis of the cooling space, but only extends to one-third of the cross-sectional area in the cooling space.

In one embodiment of the invention, the radiant boiler casing is comprised of a heat resistant plate. The radiant boiler casing can also contain pipes that are included in the radiant boiler casing in any configuration. The radiant boiler casing can also consist entirely of pipes. The pipe is used to guide any indirectly cooled media. In this case, in order to carry out the invention, the burner must be placed in close proximity to the cooling medium introduction conduit and through the hermetic radiation boiler casing ("pipe-net-pipe" design). In order to carry out the invention, it is also possible to provide a refractory lined pipe along the direction of the cooling space. DE 3809313 A1 provides a radiant boiler casing from a specific example of the prior art which contains a pipe. In order to carry out the invention, the medium is tightly guided through the annularly extending duct wall and the refractory lining to at least one burner.

In another embodiment of the invention, the other annular wall is positioned as a radiant boiler casing around a concentrically configured conduit. This may also have other conduits for cooling on the side facing the reaction space through which the cooling medium may flow. Thus, such conduits preferably extend around the geometric central axis of the reaction space to achieve an improvement in cooling.

It is also possible to arrange intermediate space between the radiant boiler casing and the inner wall of the cooling space. Between the gases, the gas can circulate through the intermediate space. An example of such a radiant boiler casing is provided in DE 10 2008 012 734 A1. In order to carry out the invention, the burner for the regenerative fuel is then guided via this intermediate space and the inner wall. The radiant boiler casing can, for example, also consist of a convection boiler which is concentrically surrounded by a cooling space in a hollow cylindrical design. EP 616 022 B1 provides an example of a specific example with a cooling space consisting of a convection boiler designed for cooling in a hollow cylindrical design. Convection boilers can also be divided into multiple sections or equipped with cooling plates on a part thereof. It is also envisaged that in order to carry out the invention, the waterfall-like cooling device is positioned behind the burner in the direction of the gas flow for the regenerative material, as is claimed, for example, in DE 10 2008 012 734 A1.

The burner feeding the regenerative feedstock via the radiant boiler casing can be designed in any manner. These burners can for example be designed as burner guns. However, such burners can also be designed as nozzles. The burner can also be configured in a tangential and concentric manner. The burner can also be configured such that it is in front of the discharge connector of the reaction space in the direction of the gas flow so that it is in the "flow shadow" of the syngas stream during operation. In this way, the burner preferably prevents slag formation. In order to carry out the invention, it is only required that at least one burner is guided tightly via the hermetic radiation boiler casing medium and guided or guided in the direction of the gas flow before introduction of the cooling gaseous, vaporous or liquid external medium in at least a portion of the cooling space Renewable fuel.

The pressure vessel of the reaction space and the cooling space can be provided as a single component having the same diameter for constructing the device. However, the reaction space and the cooling space may also be two pressure vessels having different diameters placed on each other, wherein the cooling space-pressure vessel diameter is in this case more than the reaction space-pressure The diameter of the container is large.

A method of tangentially injecting fuel into the cooling space of a gasification reactor is also claimed. The fuel can be injected in the cooling space along the direction of the gas flow or against the direction of the gas flow, but in the horizontal cutting plane of the cooling space along the corners of the reactor wall. Thereby, the residence time in the reaction space is substantially increased.

Regenerative fuels are typically used for injection. The regenerative fuel is fed concentrically tangentially into the cooling space via the at least one burner via the radiant boiler casing to generate another gas stream gasification reaction, through which the temperature of the effluent gas decreases and The enthalpy difference is used for additional gasification of the regenerative raw material ("chemical quench"). Tangential injection of fuel with extended residence time contributes to this procedure or at least facilitates this procedure.

A method of feeding regenerative fuel into the area of a radiant boiler casing of a coal gasification reactor is also claimed, wherein: - a finely powdered carbonaceous fuel and oxygen or oxygen which are concentrically or downwardly directed from the outside in a horizontal direction. a mixture of gases is injected into the refractory reaction space from above to cause the fuel to react in the reaction space to form a synthesis gas in the gas stream reaction, and the obtained synthesis gas is at a pressure of 0.5 MPa to 8 MPa and is upwardly directed Deriving from the reaction space in a downward direction, and ● after completion of the extraction, introducing the synthesis gas thus obtained into a second reaction space designed as a cooling space, and supplying the gas supplied for cooling purposes in the second reaction space Mixed with a gaseous, vapor or liquid external medium of the cooler, and characterized by - between the reaction space and the feed point for the external medium, the regenerative fuel is fed concentrically via the at least one burner into the cooling space via the radiant boiler casing to generate another gas stream gasification reaction via which With a gasification reaction, the temperature of the effluent gas decreases and the enthalpy difference is used for additional gasification of the regenerative raw material, and the regenerative fuel is injected into the cooling space at an angle along the tangential direction of the cooling space wall to make the regenerative fuel Angular momentum is received during injection into the feed gas stream from the reaction space.

All biological materials can be used as regenerative fuels, which are suitable for producing syngas with an oxygen-containing gas as a reactive gas. This regenerative fuel can be a finely chopped, crushed, finely ground energy crop, any form of wood, straw, pasture, cereals, biological residues, marine plants or livestock manure. The regenerative feedstock can be pretreated prior to gasification, wherein the pretreatment step includes, for example, drying, carbonization, milling, or a combination of such steps. For gasification, a regenerative fuel is then introduced into the cooling space with a mixture of steam or oxygen containing gas, water vapor, or oxygen containing gas and water vapor. A mixture of regenerative fuel and a carbonaceous fuel or fossil fuel can also be used as a fuel for a burner in a cooling space.

It is basically known to add a regenerative raw material to the gas stream reaction of the anthraquinone stream. EP 1027407 B1 describes a process for producing combustible gases, syngas and reducing gases from regenerative fuels and fossil fuels by burning the fuel together with gaseous oxygen or an oxygen-containing gas in a burner. DE 102009011174 A1 (not yet disclosed at the time of this application) describes a second burner level in a region extending over the total height of the reaction space, via regenerative fuel A method of adding a gasification reaction to use a synthesis gas.

DE 102010008384.4 (not yet disclosed at the time of this application) describes a method in which biofuels are concentrically introduced into a cooling space via other openings arranged in a cooling space inside the cooling space for another reaction with the syngas, thereby further Reduce the temperature of the syngas. This application introduces fuel directly into the cooling space and does not provide an indication of the complex design of tangential introduction of regenerative fuel via the radiant boiler casing.

The temperature of the syngas is typically from 1400 ° C to 1500 ° C during discharge from the reaction space, from about 1,200 ° C to 1,300 ° C after introduction of the regenerative fuel and about 900 ° C after leaving the cooling space. The temperature of about 900 ° C when leaving the cooling space is recorded using the measured value, and the remaining values are estimated values.

The burner can be configured in the cooling space in any manner. The regenerative fuel must be introduced tangentially into the cylindrical cooling space only via the tangentially disposed burners to allow the enthalpy flow in the cooling space to accept angular momentum, thereby increasing the residence time of the fuel in the cooling space. Since the burners are tightly guided via the radiant boiler casing medium, such burners are typically equipped with a sealing collar in the radiant boiler casing region. However, the sealing can be achieved in any manner and the type of sealing can be performed in any manner.

The sensible heat of the syngas can be used to generate steam. An external medium is used for this purpose, which absorbs heat from the cooling space via intercooling in a cooling plate or pipe in the radiant boiler casing. This heat can be used in downstream waste heat boilers to produce steam or high pressure steam. In order to perform the present invention, the radiant boiler casing and baffle may also be cleaned using a beater or soot blower or both.

Also advocates the use of syngas produced by the mentioned method, this syngas It can be used, for example, to generate electricity in a power plant. In addition, the syngas can be used to generate electricity in a power plant where carbon dioxide is separated from the combustion gases. An example of this use is IGCC technology (IGCC: "Integrated Gasification Combined Cycle"). Finally, it is also possible to use the syngas produced according to the invention to produce synthetic motor fuel or synthetic natural gas. Furthermore, any use of syngas produced in accordance with the present invention may be used to produce chemicals ("polygeneration").

The present invention has the advantage of using a hot syngas from a coal gasification reaction in a cooling space equipped with a radiant boiler casing. Therefore, the economic efficiency of the coal gasification process can be substantially improved. Since the regenerative fuel transfers only a small amount of ash in the gasification process, the radiant boiler casing is loaded with substantially less ash and slag by the method according to the invention. Finally, the radiant boiler casing is exposed to a substantially lower thermal load via subsequent introduction of regenerative fuel.

The invention is illustrated in more detail by means of two figures, wherein the invention is not limited to such specific examples. 1 shows a coal gasification reactor having a post gasification reaction according to the present invention, wherein the radiant boiler casing is designed from a water guiding pipe or a cooling medium guiding pipe equipped with an overlapping cooling plate. 2 shows a coal gasification reactor having a post gasification reaction according to the present invention, wherein the radiant boiler casing is composed of a cooling plate equipped with a pipe that guides the cooling medium around the cooling space above it.
