    Plant comprising a reactor, particularly for the gaseification of fossil fuels, the components coming out of the reactor still having temperatures in the range of 1500`C. In order to influence the flow, it is appropriate to vary the outlet section (35) of the reactor. According to the invention, this is to be carried out while incurring small expenses, and to this effect a good thermal insulation has to be provided also in the connection portion through which the components of the reaction are directed to the other portion of the plant (36, 37). It is proposed that, between the connection portion (14, 15) and the portion comprising the duct or plant (36, 37), there is provided an intermediary ring. This ring has also a refractory coating (34) and its inner section area determines the smallest output section of the connection portion.

    By means of the installation and the intermediate ring, annular seals are made, made of a flexible material.
    The invention relates to the chemical industry, namely to a plant for the gasification of mineral fuels
    The known installation for gasification of minerals is heatable, in the case of an inner lined body, a receiving chamber, a fitting for connecting the body with a receiving chamber having a cross section less than the cross section of the liner pji
    A disadvantage of the known installation is that the lining in the lower part of the body and in the area of the joints is solid. Such
    the implementation of the lining complicates the changeover n entails stopping
    installations for gazi kats and fuel and dropping its performance when readjusting to the desired performance.
    The purpose of the invention is to simplify the change in plant performance.
    The goal is achieved by the installation of gasification of mineral fuel}, including a housing lined from the inside, a receiving chamber, a fitting for connecting the housing to n1) a small chamber having a cross-section less than the cross section of the housing lining, equipped with a removable intermediate ring, having an inner lining, internal diameter which is less than the internal fitting.
    Moreover, the lining of the intermediate kilt is made expanding in the upper part.
    In this case, the lower end of the nozzle lining is located below its body.
    The lining of the nozzle is fixed in its housing on the console by means of supporting elements at a distance from the housing.
    Bearing elements are made in the form of cooling tubes arranged parallel to the vertical axis of the housing.
    The cooling parts in the upper part have an annular collector mounted on the console with the possibility of radial movement.
    The lining of the intermediate ring is fixed in its case on the console by means of bearing elements.
    The bearing elements of the lining of the intermediate ring are made in the form of cooling pipes, which have a ring collector in the upper part located outside the lining of the Btme fitting of its lower end.
    In addition, the cooling tubes of the lining of the intermediate ring in their lower parts are made to bend 1and inwards and provided with an annular manifold located 4 in its lining at the level of the smallest „through passage.
    The lining of the intermediate ring is expanding at the bottom.
    The lower end of the lining of the intermediate ring is located below its body.
    Between the bearing elements of the linings and the housings of the installation and the intermediate ring there are annular seals made of flexible material.
    Installing a removable intermediate ring with an inner lining, the inner diameter of which is smaller than the inner diameter of the nozzle, simplifies changeovers of the installation, does not require installation work on the refractory lining, as it does not require cooling installation to replace it, as is the case with the well-known solution.
    FIG. 1 shows the proposed installation, longitudinal section; on league. 2 shows section A-A in FIG. one; in fig. 3 - the location of the cooling tubes in the intermediate ring.
    The installation for gasification of mineral TOSH1IV includes the inside of a housing 1, a receiving chamber 2, a fitting 3 connecting the housing 1 with the receiving chamber 2 and having sections smaller than the cross section of the liner housing 1. The installation is equipped with a removable intermediate ring 4 having an internal lining 5, internal diameter which is smaller than the internal diameter of the fitting 3. “The lining 5 of the intermediate ring 4 is made expanding in the upper part, and the bottom torus of the lining 6 of the fitting 3 is located not on its body 7. The lining 6 of the fitting is fixed in its body 7 n and the console 8 by means of supporting elements 9 at a distance from the housing 7. Bearing elements 9 are embedded in the form of cooling tubes located on the vertical axis of the housing 7. Bearing elements 9 in the upper part 1 are welded to hemlock collectors 10 mounted on the brackets 8 radial movement. The lining 5 of the intermediate ring A is fixed in its housing 1 on the cantilever 12 by means of supporting elements t3, which are made in the form of coolings c1 {x pipes and tubes in the upper part of the annular collectors 14, located outside the lining 6 of the fitting 3 above its bottom end. The bearing elements 13 of the lining 5 of the intermediate ring 4 in the lower part are made inwardly bent and provided with annular collectors 15 located in its lining at the level of its smallest section. The lining 5 of the intermediate ring 4 is made widened at the bottom, and the lower end of the lining 5 of the intermediate ring 4 is located below its Koprtyca fl. Between the bearing elements 9 and 13 4 Uterovok 5 and 6 and the housings 7 and 11 are installed annular seals 16, made of flexible material. The refractory lining 6 applies the cage formed by the cooling pipes (support elements) 9. The upper parts of the cooled pipes enter the annular collector 10, which is located on the consoles 8. The lower ends of the protective pipes 9 in the lower part are connected to the annular collector 17. The upper collector 10 is divided by its circumference into at least two segments. The left section of the collector 10 is connected to the inlet pipe 18, the right section to the outlet pipe 19. The inlet pipe 18 and the outlet pipe 19 lead to a central supply system (not shown). In order to compensate for thermal expansions, compensators 20 are inserted into the inlet 18 and outlet 19 pipelines. The cooling pipes 9 are connected to each other around the circumference by sheet walls 21 (Fig. 2). On the cooling pipes 9, as well as on the ring collectors 10 and 17, anchors 22 are welded, which are included in the refractory lining 6 with their forked ends and rigidly connect it to the cage formed by the cooling pipes 9 and ring 1 and collectors Yu and 17. ring collector 10 on console 8 allows the collector to move in the radial direction, which compensates for temperature expansions. The sealing rings 23 are located between the housings of the fitting 3, the intermediate ring 4 and the receiving chamber 2. The collector 14 is divided into sections extending for 90. A supply pipe 24 is connected to one section of the annular collector 14. The refrigerant flows through the supporting elements 13 leaving this section into the lower annular collector 15 and from there into the right (Fig. 3) section of the upper annular collector 14. From there, the refrigerant goes through a discharge pipe 25 to the central source (not shown) of the refrigerant. The disassembly and assembly of the intermediate ring consists of a connector of flanged connections, with which the intermediate ring can be used. A is fixed on housing 1. If, for affecting the reaction progress in the inside of the reactor vessel, another output section is needed, the intermediate ring 4, which is mounted depending on the circumstances, is replaced by another intermediate ring that has the desired flow area. A reduction in the passage cross section leads to an increase in the residence time of the reaction components in the reactor vessel and, thus, to a reduction in throughput. An increase in the transverse cross section is also possible, and this increase is certainly limited due to the fact that from a technical point of view it makes sense only to the same diameter as the inner diameter of the lining of the connecting nipple. With a further increase in the transverse cross section in the intermediate ring, the transverse cross section in the connecting nipple as the smallest passage cross section, it would even be largely decisive for the output velocity of the product action and thus for the KOMijoHeHTOB time in the reactor tank, the Advantage) of the invention is that to prepare for the connecting area of another part of the installation or pipeline or to change the output section of the reactor tank, installation of the heat-resistant lining of this reactor tank is not required. The intermediate ring is only a relatively small CONSTRUCTIVE detail with respect to the reactor vessel itself, and this part may be available in several instances with different internal cross-sectional sizes. If it is necessary to attach an additionally connected part of the installation or a change in the internal cross section in the output region of the reactor tank, it is sufficient to change the intermediate ring. For this, it is only necessary to disconnect the screw connection between the housings of the connecting connection and the intermediate ring, and in this case the reactor tank should be somewhat raised. These works are carried out after a short cooling time, since there is no need to hold them over the lining itself as the most heated area. In this case, all work can be carried out outside. V An advantage of the invention is that the cross section of the lining of the intermediate ring expands in the upper part, thereby making it possible to lining the intermediate ring to such a height that it can encompass the lower part of the connecting nipple. In this case, the direct passage of heat in the radial direction is absent and it is advisable to place the lower end side of the lining of the connecting nipple below its body. A variant of the installation is possible when the lining of the connecting nipple inside its body is fixed on the console with the help of several elements, due to which an annular space is created, which makes it possible to fix the lining of the intermediate ring if the lining of the connecting nipple enters the intermediate ring. Bearing elements can be made predominantly as cooling pipes that run parallel to the vertical axis of the outer shell. The cooling tubes provide the possibility of supplying the cooling medium as closely as possible to the especially strongly heated lining areas, the formation of the structural element of the rigidity of the lining,,. In addition, the cooling tubes may have an annular manifold in the upper region, which is radially displaceable on the cantilever. At the same time, the collector is at the same time an integral part of the structural element of the liner stiffness. Its radially movable support makes it possible to compensate for different thermal expansions between the cooling pipe and the annular collector of the supporting structure, on the one hand, and the lining, on the other hand. The lining of the intermediate ring can be fixed with the help of bearing elements on the console, due to which the lining of the lining of the intermediate ring attached at the height of the console is possible. The use of a cantilever allows only a small connecting area between the lining and the body to compensate for different thermal expansions. The lining support elements of the intermediate ring can also be made as cooling pipes, which in the upper part have an annular manifold located outside the lining of the connecting nipple and above the lower end plane of the lining of the connecting 7 nipple, which makes it possible to insert the connecting nipple in the cooled area of the intermediate ring and its lining. Thus, the end area of the lining of the intermediate ring and the connecting nipple is also intensively cooled in the transitional area with full efficiency. , t. According to the following embodiment of the invention, it is proposed that the cooling tubes of the lining of the intermediate ring in the lower part of this ring be folded inwards and provided with an annular collider, located at a height. the narrowest flow area of the intermediate ring lining. Due to this, the collector in the most narrow transverse section (L4 of the intermediate ring lining contributes directly to the cooling of the coolant and at the same time provides an emphasis in this medium-sized area. The cooling pipes are laid in such a way that the bottom of the burner ring extends from the narrowest cross section At the same time, the cell formed by the cooling tubes to the cooling tube receives, before the end of the intermediate ring facing the reactor tank, the relative side from the reactor tank This cylindrical form 818 allows to move the ring lining into the connected part of the installation or pipeline with a relatively small gap so that the ring lining can form a transition with the lining of the connected part of the installation or pipeline Preferably, the bottom end surface of the intermediate ring lining is located deeper than the outer shell of this. Yeduzhi with the existing elements of the lining of the case are installed, as necessary, ring seals of elastic material, Oops serve as gas shut-off elements, and prevent gas streams from entering the space, located between the lining and the body as needed. The refractory lining of the connecting nipple and the intermediate ring can be made entirely of shlh partly from heat-resistant building materials, or by heat-resistant building masses. If the lining consists of heat-resistant building masses, the cooling tubes and / or steel sheets and / or manifolds located between them can be equipped with anchors that enter the layers of the building mass and can be fixed to these parts due to conventional welding.
