Description

  The present invention relates to a water gas burner that generates water gas by heating a carbon-containing aqueous solution, burns the water gas, and injects a high-temperature (1,000 ° C. or higher) flame.

  It has long been known that synthesis gas composed of carbon monoxide and hydrogen, so-called “water gas”, is produced by reacting carbon with high-temperature steam. Water gas is produced by gasifying coal or by gasifying waste or waste carbide, and is used directly as a gaseous fuel for combustion. Hydrogen is used as fuel for fuel cells. For example, Patent Document 1 proposes an apparatus and a method for directly heating water with a high-temperature flame to generate high-temperature superheated steam, and generating water gas from carbon in waste using the superheated steam. Yes.

JP 2006-199838 A ([0031])

  Conventionally, the generated water gas is recovered and used as a gaseous fuel for combustion or fuel for a fuel cell. However, if it is used as a gaseous fuel for combustion, the water gas is combusted at the same time as it is generated. It is preferable that it can be utilized in the embodiment. Here, since the water gas also contains carbon monoxide in addition to hydrogen, it is necessary to completely burn carbon monoxide when the generated water gas is used in a mode in which it is burned simultaneously. However, conventionally, only an apparatus and a method have been proposed regarding a mode in which water gas is generated and recovered and used, and there is no apparatus and method used in a mode in which water gas is combusted simultaneously with generation. There was no apparatus and method for complete combustion of carbon monoxide. Therefore, in order to develop a burner that simultaneously burns while generating water gas and completely burns carbon monoxide, that is, a water gas burner was studied.

  As a result of the study, the production preparation device, the production reactor, and the complete combustor are connected, and the production preparation device injects a flame into the atomized carbon-containing aqueous solution to produce heated carbon and steam, The production reactor produces water gas from the heated carbon and water vapor fed from the production preparation device, and the complete combustor completely burns the water gas fed from the production reactor to inject a flame. A water gas burner was developed. Specifically, the production preparation device is a cylinder that is closed at both ends, a heating source that injects a flame is attached to one end, one end of the production reactor that is closed protrudes to the other end, and a carbon-containing aqueous solution is injected. A raw material spray nozzle is projected between the heating source and the closed end of the production reactor, and an extrusion air hole is provided in the vicinity of the heating source. The production reactor is a cylinder that is closed at one end and open at the other end. The closed end protrudes from the other end of the production preparation device, and the other open end protrudes from one end of the complete combustor. The communication air hole is provided on the side surface of the range protruding from the production preparation device. The complete combustor is a cylinder whose one end is closed and the other end is open. The other end of the open production reactor projects to one end, and an injection air hole is provided near the other end of the production reactor. Composed.

  The production preparation device heats the carbon-containing aqueous solution sprayed from the raw material spray nozzle by spraying a flame sprayed by a heating source to produce heated carbon and water vapor that are raw materials for producing the water gas. Then, flame, heated carbon, and water vapor are sent to the production reactor through the communication air holes by the air blown from the extrusion air holes. The carbon-containing aqueous solution means an aqueous solution in which carbon or a carbon compound that can be used for the production of water gas is mixed, and an aqueous solution in which carbide powder is mixed can be exemplified. In the case of an aqueous solution in which carbide powder is mixed, when the aqueous solution in which carbide powder is mixed is sprayed into the production preparation device, the powdered carbide becomes heated carbon by the flame injected by the heating source, and Water becomes water vapor, and raw materials necessary for the production of water gas are instantly generated. The heating source is not limited as long as it can inject a flame, and various conventionally known burners using various solid fuels, liquid fuels, or gaseous fuels can be used. The extrusion air hole feeds air into the production preparation device, raises the internal pressure of the production preparation device to extrude the flame, heated carbon and water vapor toward the production reactor, and the flame through the communication air hole, Heated carbon and water vapor are fed into the production reactor.

  The production reactor reacts the flame sent from the production preparation device through the communication air hole, heated carbon and water vapor to produce water gas, and burns the water gas produced by the flame. The production reactor protrudes from the other end of the production preparation device, and is a cylindrical body having a relatively smaller volume than the production preparation device due to the structure in which flame, heated carbon and water vapor are fed from the communication air holes provided on the side surface. It is understood. From this, feeding heated carbon and steam from the production preparation device to the production reactor will consolidate the heated carbon and water vapor that expands according to the volume of the production preparation device into the production reactor, and the heating The reaction of generated carbon and water vapor can be promoted. As a result of the heated carbon and water vapor being concentrated, the internal pressure of the production reactor is increased. As a result, the flame of the production reactor and the produced water gas are relatively released from the production preparation device by opening the other end. It is sent to the complete combustor where the internal pressure is lowered.

  In the complete combustor, the other open end is configured as a flame injection port, and the air (especially oxygen) injected from the injection air hole into the flame and water gas (especially carbon monoxide) sent from the production reactor. To complete combustion and complete combustion of water gas. As described above, the air injected from the injection air hole has a function of pushing out the flame toward the other open end in addition to aiming at complete combustion of the water gas. Further, the complete combustor is a cylindrical body having a relatively larger volume than the production reactor due to the structure in which the other end of the production reactor is protruded from one end and an injection air hole is provided in the vicinity of the other end of the production reactor. It is understood. From this point, sending the flame and water gas from the production reactor to the complete combustor expands the flame and water gas that are aggregated according to the volume of the production reactor in the complete combustor. The internal pressure of the combustor is relatively lowered, and the difference in the internal pressure also contributes to the flame injection.

  Extrusion air holes blow out the air that pushes out the flame, heated carbon and water vapor, communication air holes communicate the production preparation device with the production reactor, and the injection air holes completely burn the water gas and inject the flame It is sufficient if air can be supplied. However, from the viewpoint of facilitating the movement of the flame, heated carbon, water vapor and water gas from the production preparator through the production reactor to the complete combustor, and suppressing the spread of the flame in the production preparator and the complete combustor, The production preparation device is provided with a plurality of extrusion air holes inclined in the direction toward the production reactor, that is, toward the production reactor and in the tangential direction of the inner peripheral surface, and the production reactor is directed to the other end, ie, the complete combustor. A plurality of communication air holes inclined in the direction and tangential direction of the same inner peripheral surface as the extrusion air holes are arranged in a ring shape, and the complete combustor is in the direction toward the other end, that is, the injection port, and the same as the extrusion air holes A plurality of blast air holes inclined in the tangential direction of the inner peripheral surface may be arranged in a ring shape. As a result, the air blown out from the extrusion air holes and the jet air holes forms a swirling flow in the same direction (tangential direction of each inner peripheral surface), suppresses the spread of the flame, and the communication air hole forms a swirling flow of the air. A smooth flame, heated carbon, water vapor and water gas transfer are realized.

  Here, if the air blown into the production preparation device from the extrusion air holes or the air blown into the complete combustion device from the injection air holes is at a low temperature, the temperature inside the production preparation device or the complete combustion device may be lowered. In particular, because the inside of the production preparation device generates heated carbon and water vapor, and further needs to be maintained at a high temperature (900 ° C. or more) necessary for production of water gas by the heated carbon and water vapor in the production reactor, It is preferable that the air blown from the extrusion air hole to the production preparation device or the air blown from the injection air hole to the complete combustor is as close to the flame temperature as possible. Therefore, the production preparation device is provided with an air-cooling jacket at least near the heating source, and the production preparation device is air-cooled and heated by connecting the air-cooling jacket and one or both of the extrusion air hole and the injection air hole with a distribution pipe. It is good to suppress or prevent that the temperature inside a production | generation preparatory device or a complete combustor falls by blowing out the air which passed through the extrusion air hole or the injection air hole. In this case, the air supplied to the air-cooling jacket is heated and the pressure is increased, so that there is an advantage that the ejection speed of the air ejected from the extrusion air holes and the ejection air holes is increased and the formation of a high-speed swirling flow is facilitated.

  A feature of the present invention is that a carbon-containing aqueous solution is sprayed inside the production preparation vessel, and a carbon or carbon compound is immediately heated to a high temperature and water is immediately vaporized by a flame injected by a heating source, so that the water gas in the production reactor is It is in the point of facilitating the generation. In the present invention, in order to realize easy production of water gas, a production preparation device is interposed between the production preparation device and the complete combustor, and the production preparation device and the complete combustion device are connected via the production reactor. is doing. Here, when considering efficient generation of heated carbon and water vapor in the production preparation device, the production preparation device protrudes and sprays the raw material spray nozzle with the injection direction of the carbon-containing aqueous solution directed to one end of the production reactor. Preferably, the carbon-containing aqueous solution is struck against one end of the sealed production reactor and diffused. Then, from the viewpoint of promoting the diffusion of the carbon-containing aqueous solution, the production reactor projects one end sealed by a sharp cone-shaped lid toward the heating source at a position facing the heating source of the production preparation device. Good.

  According to the present invention, it is possible to provide a water gas burner that completely burns carbon monoxide by continuously burning while generating water gas easily and achieving complete combustion of the water gas. The water gas burner of the present invention generates heated carbon and water vapor that are raw materials for generating water gas by heating a carbon-containing aqueous solution sprayed inside the production preparation device with a flame. Here, since the carbon or carbon compound contained in the carbon-containing aqueous solution can use a carbide of waste, the present invention has a side of waste treatment. Further, since the generated water gas is immediately combusted, combustion of carbon monoxide becomes a problem. However, the present invention does not cause the problem because the complete combustor completely burns carbon monoxide. Thus, the present invention provides a new utilization mode of water gas as a water gas burner.

  Hereinafter, embodiments of the present invention will be described with reference to the drawings. FIG. 1 is a block diagram showing an example of the water gas burner 4 of the present invention, FIG. 2 is an axial cross-sectional view of the water gas burner 4 of this example, and FIG. . In this example, an aqueous solution in which carbide powder is mixed (hereinafter referred to as “charcoal mixed water”) is used as the carbon-containing aqueous solution. 1 and 2, the left side or left direction on the paper surface is the rear end side or rear side, and the right side or right direction on the paper surface is the front end side or front side. From FIG. 3, the front side orthogonal to the paper surface is the front end side or the front side, and the rear side orthogonal to the paper surface is the rear end side or the rear side.

  As shown in FIGS. 1 and 2, the water gas burner 4 of the present example includes a production preparation device 1, a production reactor 2, and a complete combustor 3 that are cylindrical bodies in the axial direction (see FIGS. 1 and 2). The flame F at about 1,100 ° C. is injected from the flame injection port 33 of the complete combustor 3. The water gas burner 4 of the present invention requires a heating source 12 of about 1,000 ° C. to generate water gas. However, the generated water gas is immediately burned and the final flame F is injected to reduce the amount of heat. It can be greatly increased. From this, compared with the case where the heating source 12 is used as a single burner, the water gas burner of the present invention is particularly suitable for use requiring a heat amount.

  The production preparation device 1 has a multistage configuration in which a rear cylinder 14 to which a heating source 12 composed of a liquid combustion burner is attached and a front cylinder 15 to which the production reactor 2 is connected are connected. The rear cylinder 14 needs only to have a capacity to which the heating source 12 can be attached, and is smaller than the front cylinder 15 because the flame F injected by the heating source 12 needs to be narrowed down. On the contrary, the front cylinder 15 secures a space in which the coal-mixed water is heated by the flame F to expand the volume, and the heated carbon and water vapor are circulated to the production reactor 2 from the communication air hole 21. Since it needs to be fed, it is made larger than the rear cylinder 14. Since the production preparation device 1 includes the heating source 12 and the production reactor 2 only has to protrude inside, the production preparation device 1 may not have a multi-stage configuration as in this example.

  The rear cylindrical body 14 is a hollow cylindrical body in which a rear air reservoir 145 having an annular cross section is made of a steel plate. The heating source 12 is inserted into a hollow portion formed by the rear air reservoir 145 and the rear is sealed. Since the production preparation device 1 is required to have heat resistance in a high-temperature (about 1,000 ° C.) atmosphere, it can be considered that the production preparation device 1 is made of heat-resistant ceramics instead of steel plates. The heating source 12 of this example uses a gas burner made of liquid fuel. The liquid fuel to be supplied is adjusted by a liquid fuel adjustment valve 49 to adjust the amount of heat of the flame F. The rear air reservoir 145 has a front end surface closest to the flame F injected from the heating source 12 as an inclined surface, and a plurality of extrusion air holes 11 are opened in the circumferential direction of the front end surface. Further, a rear air cooling jacket 141 is wound around the rear end surface of the front cylindrical body 15 to suppress or prevent deterioration of the connection portion between the rear cylindrical body 14 and the front cylindrical body 15 due to the flame F due to high temperature. .

  The rear air cooling jacket 141 is supplied with compressed air from an air cooling high-pressure blower 41 installed outside the water gas burner 4. In this example, the rear air cooling jacket 141 and the rear air reservoir 145 are connected by the rear distribution pipe 142, and the air heated by the rear air cooling jacket 141 is supplied to the rear air reservoir 145, and forward from the extrusion air hole 11 I try to erupt towards you. Here, as shown in FIG. 3, the extruded air hole 11 is inclined and opened in the circumferential direction, so that the ejected air forms a swirling flow W. This swirl flow W is represented by the reference symbol G in this example, in addition to the flame F injected by the heating source 12, as well as the carbon, water vapor, or water gas G heated by the flame F. ) Is sent out toward the production reactor 2 in the forward direction. The flow velocity and flow rate of the swirling flow W are adjusted by the rear adjustment valve 143 based on the rear pressure gauge 144 provided in the rear distribution pipe 142.

  Like the above-described rear cylinder 14, the front cylinder 15 is formed by forming a front air cooling jacket 151 having an annular cross section with a steel plate, the rear end is closed by connecting the rear cylinder 14, and the front end is formed by the production reactor 2. It is a sealed hollow cylindrical body that is connected and closed. The raw material injection nozzle 13 protrudes from the side surface between the heating source 12 and the closed end 22 of the production reactor 2 protruding from the front to the middle in the front-rear direction, and sprays the coal-mixed water toward the closed end 22. As a result, the sprayed charcoal mixed water diffuses within the range of the flame F swirling in accordance with the swirling flow W described above, the carbide in the charcoal mixed water, that is, carbon is instantaneously heated, and the water is instantaneously converted into water vapor. Become. The raw material spray nozzle 13 of this example is a charcoal mixed water sprayer 47 that combines charcoal mixed water supplied from a charcoal mixed water tank 46 by a charcoal mixed water supply pump 45 and compressed air supplied from a high-pressure blower 42 for spraying. Mix and spray. The flow rate of the supplied charcoal mixed water is appropriately adjusted by the charcoal mixed water flow rate adjusting valve 44, and the supplied compressed air is appropriately adjusted by the air flow rate adjusting valve 43.

  The front air cooling jacket 151 suppresses or prevents the side surface of the rear cylindrical body 15 to which the swirling flame F approaches from deterioration due to high temperature. The front air cooling jacket 151 is supplied with compressed air from an air cooling high-pressure blower 41 installed outside the water gas burner 4. In this example, a front air cooling jacket 151 and a front air reservoir 32 to be described later are connected by a front distribution pipe 152, and the air heated by the front air cooling jacket 151 is supplied to the front air reservoir 32, and the jet air holes 31 are provided. It spouts out from the front. Here, the injection air hole 31 is inclined and opened in the same circumferential direction as the extruded air hole 11 described above, and in addition to the complete combustion of the water gas by the supply of air, the finally injected flame F is air. (See FIG. 3). The flow velocity and flow rate of the swirling flow W are adjusted by the front adjustment valve 153 based on the front pressure gauge 154 provided in the front distribution pipe 152.

  The production reactor 2 is made of a steel plate as in the production preparation device 1 described above, and the rear end, which is the sealed end 22, protrudes rearward from the front end of the front cylindrical body 15 of the production preparation device 1 and is opened. It is a cylindrical body in which the front end protrudes forward from the rear end of the complete combustor 3 described later. The sealed end 22 has a conical shape that protrudes rearward so as not to hinder the diffusion of the coal-mixed water sprayed from the raw material spray nozzle 13. The communication air hole 21 is provided on a side surface of the range protruding to the generation preparation device 1. Here, the communication air hole 21 is inclined and opened in the same circumferential direction as the extruded air hole 11 described above, and the flame F and the heated carbon, water vapor, or water gas G smoothly communicate with the swirl flow W. The air can be fed into the production reactor 2 through the air holes 21 (see FIG. 3).

  The carbon and water vapor G heated by the flame F in the production preparation device 1 are set to a high temperature (about 1,000 ° C.) necessary for the atmospheric temperature at which the flame F reacts with the carbon and water vapor to produce water gas. However, since the reaction for generating the water gas is an endothermic reaction, carbon and water vapor do not sufficiently react in the generation preparation device 1. Therefore, the water gas burner 4 of the present invention takes carbon and water vapor G heated together with the flame F into the production reactor 2 having a small volume, and reacts the carbon and water vapor in a state where a sufficient amount of heat is secured, Water gas is produced in the production reactor 2. At this time, since the heating source 12 of the production preparation device 1 injects the flame F toward the production reactor 2 and is taken into the production reactor 2 through the air communication hole 21, the production reactor 2 is wrapped in the flame F. Since the production reactor 2 itself is at a high temperature (about 1,000 ° C.), the atmospheric temperature in the production reactor 2 can be hardly lowered. In this example, a temperature sensor 48 is projected from the side surface of the front cylindrical body 15 of the production preparation device 1 toward the side surface of the production reactor 2 so that the heating temperature of the production reactor 2 can be monitored.

  In the complete combustor 3, like the production preparation device 1 described above, the front air reservoir 32 having an annular cross section is formed of a steel plate, the rear end is closed by connecting the opened front end of the production reactor 2, and the front end is closed. This is a hollow cylindrical body having an open flame injection port 33. In order to inject the flame F combusted with the water gas, the inner diameter of the production reactor 2 is slightly larger than the open front end, but the flame injection port 33 basically faces the front so as to throttle the flame F. The side shape of the truncated cone is very narrow. The front air reservoir 32 forms a heat insulation layer provided over the entire length of the complete combustor 3, and has a rear end surface closest to the opened front end of the production reactor 2 into which the flame is injected as an inclined surface, A plurality of holes 31 are opened inclining in the same circumferential direction as the extruded air holes 11 described above (see FIG. 3).

  As described above, the air ejected from the ejection air hole 31 is supplied from the front air cooling jacket 151 connected by the front distribution pipe 152. The air thus supplied to the front air reservoir 32 is discharged from the front end by supplying fresh air (especially oxygen) toward the front end of the production reactor 2 which is ejected from the injection air hole 31 and supplied to the front end. In addition to the complete combustion of the water gas G, the swirl flow W is formed to narrow down the flame F, and further push out the flame F toward the flame injection port 33. Here, since the air injected from the injection air hole 31 has already been heated in the front air cooling jacket 151, the temperature of the flame F is not lowered.

  The above-exemplified water gas burner was prepared, and a combustion test was actually performed. The generation preparation machine consists of a steel plate with a thickness of 10 mm and a longitudinal cylinder of 250 mm in the front and rear, and an outer diameter of 125 mm including the rear air reservoir, and a steel plate with a thickness of 10 mm and a longitudinal length of 500 mm, and an inner diameter of 210 mm excluding the front air cooling jacket. In a configuration in which the front cylinder is connected, a rear air-cooling jacket having a width of 50 mm in the front-rear direction is wound around the rear end face of the front cylinder. The extrusion air hole has a hole diameter of 10 mm, and is inclined 40 degrees from the normal direction to the tangential direction when viewed from the front to form a counterclockwise swirl flow. The production reactor is configured as a cylindrical body with a plate thickness of 10 mm and a longitudinal length of 350 mm and an outer diameter of 90 mm, and 40 communicating air holes with a hole diameter of 10 mm are provided on the side surface at equal intervals. The communication air holes are inclined in the same manner as the extrusion air holes. The complete combustor is configured as a cylindrical body with a steel plate having a thickness of 10 mm and a longitudinal length of 250 mm and an outer diameter of 135 mm including a front air reservoir. The injection air hole has a hole diameter of 10 mm and is inclined in the same manner as the extrusion air hole, and forms a counterclockwise swirling flow.

  The carbon-containing aqueous solution used as a raw material in the examples is a coal-mixed water obtained by mixing 300 g of pulverized coal per 10 liters of water. The pulverized coal preferably has a particle size of 70 μm or less, and can be easily obtained as a carbide obtained by carbonizing bamboo trees or agricultural crops, for example. Here, since the carbides have a small range that can be used as they are, and many of them are disposed of in landfills, the present invention expands the range of use of such carbides, that is, an aspect of achieving effective use of waste treatment. Have The proportion of carbon in the coal-mixed water of the example is 2.91%. Here, since it is preferable that the pulverized coal in the coal-mixed water is dispersed as uniformly as possible, the coal-mixed water in the coal-mixed water tank is stirred from the start of the combustion test of the water gas burner to during combustion. I kept doing it.

  As a heating source, a burner using kerosene as fuel was used. The kerosene supplied was 10.5 liters per hour, and when a flame of 15 to 20 minutes was injected, it was confirmed that the internal temperature reached 1,060 ° C. by the temperature sensor inserted from the side of the preparation device. Although the temperature of the production reactor cannot be known directly, since the temperature sensor measures the temperature very close to the production reactor, it can be estimated that the temperature of the production reactor is also around 1,060 ° C. At this stage, since no water gas is generated, no flame injection is observed from the flame injection port of the complete combustor. In other words, it is understood that the flame of the heating source works only for heating the production preparation device and the production reactor.

  After confirming that the temperatures of the production preparation device and the production reactor have reached 1,060 ° C., the charcoal mixed water pump, the air-cooling high-pressure blower, and the spraying high-pressure blower are started to operate. As a result, the raw material spray nozzle starts spraying the charcoal mixed water into the production preparation device, and the air supplied to the rear air reservoir through the rear air cooling jacket and the rear distribution pipe enters the production preparation device from the extrusion air hole to the front of the production preparation device. The air supplied to the front air reservoir through the air cooling jacket and the front distribution pipe is respectively injected into the complete combustor from the injection air hole. In this combustion test, the spray amount of charcoal mixed water was 16.5 liters per hour. The spray amount of this charcoal mixed water is proportional to the amount of water gas generated, but the increase in spray amount requires an extra amount of heat to generate water vapor, and the generation of water gas is an endothermic reaction. When it is desired to increase the amount of heat of the finally injected flame, it is preferable to increase the spray amount and enhance the flame of the heating source.

  When spraying of the coal-mixed water is started, a flame in which water gas is combusted starts to be injected from the flame injection port of the complete combustor. Immediately after the start of the flame injection, the complete combustor has not yet been heated sufficiently, so the flame temperature was about 1,000 ° C. The temperature reached over 1,050 ° C. Further, the presence of carbon monoxide was not confirmed in the flame in the steady state, and it was proved that the water gas was completely burned. In addition, the amount of heat of the flame injected from the flame injection port was about 192,000 cal, and the amount of heat of the burner using kerosene as fuel was about 96,000 cal, so an increase of about 96,000 cal by water gas was confirmed. That is, the water gas burner of the present invention can obtain about twice as much heat as a burner using kerosene as fuel. In other words, the water gas burner of the present invention can obtain a large amount of heat while reducing the amount of kerosene and at the same time treating the waste carbide.

  The water gas burner of the present invention is used in applications that require a large amount of heat as compared with the case where the heating source is used as a single burner. Specifically, steam (water vapor) generating boiler burners, hot air generators and incinerator auxiliary burners can be exemplified. Here, since the water gas burner of the present invention can completely burn up to carbon monoxide, there is an advantage that the post-treatment of carbon monoxide for the injected flame becomes unnecessary, and installation of equipment including the water gas burner is provided. There is an advantage that the installation area is not limited and there is no possibility of causing poisoning damage due to leakage of carbon monoxide, and the installation location is not limited. Thus, the present invention makes it possible to use a new water gas burner in a field where it has been difficult to use a conventional burner by increasing the amount of heat and the degree of freedom of installation.
