    An improvement in the process for the gasification of a solid fuel wherein the solid fuel is at least partially oxidized at a temperature above the melting point of ash of the solid fuel and at a pressure of 10-200 bar where the resultant synthesis gas is thereafter cooled in the presence of combustion residues of the solid fuel, and the combustion residues are thereafter discharged directly, the improvement residing in carrying out the gasification in a gasification zone disposed vertically over and in fluid communication with a radiation zone comprising cooling surfaces, the radiation zone have disposed at the bottom thereof and in fluid communication with the radiation zone a water containing bath. The radiation zone is cylindrical or conical, widens by 0 to 15 degrees towards the bottom, is made in a finned wall construction with a relation of height to diameter of </=6:1 and comprises cooling surfaces. A jet centrally placed in the radiation zone for introducing synthesis gas and combustion residues from the gasification zone into the radiation zone at a flow rate of 1-30 m/sec. The effluents from the gasification zone are directed into the radiation zone and into contact with the water containing bath, whereby combustion residues are retained by the bath. Synthesis gas can thereafter be removed from the radiation zone and further cooled in a convection chamber. Also disclosed is an apparatus for carrying out the process.

    (54) DEVICE for; OBTAINING SYNTHESIS GAS J The invention relates to gas generators, in particular, to an apparatus for producing synthesis gas. A device for producing synthesis gas is known, comprising a gasification chamber and a cooling chamber with a water bath, located under the gasification chamber and provided with a pipe for removing slag and synthesis gas, located above the surface of the water. The disadvantage of this device is that the liquid and plastic slag particles contained in the synthesis gas are not completely separated from the gas and the slag particles carried away by the gas flow are deposited in the gas. pipe for removal of synthesis gas, which ultimately leads to blockage of the pipe and reduce the reliability of work. The closest to the proposed technical entity is a synthesis gas production device, including a gasification chamber, a cooling chamber with a water bath, located under the gasification chamber and equipped with external cooling pipes, water cooled valves, a slag removal pipe and a drain pipe synthesis gas, located above the surface of the water bath in the upper part of the gasification chamber 12. A disadvantage of the known device is that it does not prevent the clogging of the pipe to prevent a synthesis gas, which also reduces reliability. The purpose of the invention is to increase reliability by reducing the blockage of the pipe for discharging the synthesis gas. This goal is achieved by the fact that in the device for producing synthesis gas, which includes a gasification chamber, a cooling chamber with a water bath, located under the gasification chamber and equipped with a refrigeration unit. pipes and pipes for removal of slag and syngas, cooling pipes located in the cooling chamber, a pipe for removal of synthesis gas is located in the engineering part of the cooling chamber at an angle to the surface of the native bath. The drawing schematically shows the device, a general view. The device includes a chamber I gasification, in the bottom of which is located. There is a nozzle connected to cooling chamber 2. Chamber 2 is equipped with refrigeration pipes 3 located at a distance from the walls. In the lower part of chamber 2, water is placed on the bath 4, which is connected through a pipeline to gateway 5 to discharge residues suspended in water. Above the surface of the water bath is a downwardly inclined pipe 6 for discharging synthesis gas, which can be connected to the convection chamber 7 for further cooling of the synthesis gas. The distance between the surface of the water bath 4 and the outlet of the gasification chamber 1 is 0.5-6-6 times the inner diameter of chamber 2. The device works as follows.: The volume in the gasification chamber 1 is synthesis gas and the remainder, which consists of large agglomerates and small droplets carried away by the gas stream, with a speed of 1-30 m / s, the nozzle is fed centrally into the chamber 2 located under the gasification chamber 1, which is equipped with refrigeration pipes 3. At the same time, the large agglomerates are fed through the chamber 2 and the water bath 4. Carried away ha ovym flow of fine droplets tightening .verdevayut p.ri passing through the chamber 2 and the retracting syngas Th Res pipe 6 greatest part of solidified particles falls in a water nuyu.van well by the centrifugal force. The fine particles that are carried away by the exhausted synthesis gas harden to the point that they do not cause clogging or clogging of the tubes 6. These small pieces also clog the convection chamber 7, in which the gas is further cooled. Synthesis gas, which, with increased velocity, centrally enters the chamber 2 from above, is a turbulent jet, which carries away the gasification residues and thereby prevents their contact with refrigerators 1 rub 3 or with a chamber arch 2. To completely eliminate contact synthesis gas with a chamber wall 2 spaces between the individual refrigeration pipes 3 in the circumferential direction of the closed welded bridges. Therefore, the shift can be made of steel. Thus, the wall can not be supplied with a lining. Chamber 2 may be made cylindrical or 0-15 ° conically expanding downward. PRI me R. From chamber I of gasification, in which 13,780 kg / h of coal water slurry is gasified, at 1390 ° C and pressure of 37 bar, 14,380 kg / h of synthesis gas is withdrawn through the exhaust nozzle with a diameter of 965 mm, which carries 1,215 kg / slag, 256 kg / h of unburned carbon and 5416 kg / h of water vapor. Then the gas flow i is passed through a chamber 2 with a length of I3 m and a diameter of 3.8 m, directly located below the gasification chamber 1, having a cooling surface of 83 m, which is a crown of pipes 57x4 mm in size with a pitch diameter of 3 m. After cooling to synthesis gas, the water bath deviates from the water bath in the lower part of the chamber and is discharged from chamber 2 to the side 6. Pipe 6. 924 kg / h of slag and .246 kg / h of unburned carbon enter the water bath 4. Together with the gas flow from the cooling chamber 2, 290 kg / h of unburned carbon was carried away. No clogged pipe 6 is observed. From the vbd bath 4, the removal of ..L20 .000 kg / h of water at 186 ° C, which can be used to preheat the desalted feedwater supplied to the cooling pipes 3. In the refrigeration pipes 3, the desalted water is converted into steam. Placing the cooling pipes inside the cooling chamber and the pipes for synthesis gas in the lower part at an angle to the surface of the bath allows to intensify the heat exchange, which makes it possible to cool small particles of slag to: the temperature at which they lose stickiness and do not clog pipe for removal of slag, which in turn ensures the reliability of the device.
