    The invention relates to a plant for utilization of low-potential waste heat of a gas-pipeline compressor station in a heat consumer which is outside the station such as e.g. district heating systems for homes, for industrial or agricultural purposes. The compressor stations of this type have a compressor driven by a gas motor or gas turbine. The improvement is in that a surface heat exchanger (7) cooled with liquid, preferably with water is provided for cooling the gas after leaving the compressor and being warmed in the course of compression. The heat exchanger is connected to the heat consumer through a liquid conduit having a circulation pump in it (FIG. 1).

    The invention relates to installations for the utilization of waste heat with a low potential from gas compressor stations at heat consumers outside the gas compression cycle.
    A known installation for utilization of low-grade waste heat from a compressor station outside the compression cycle includes: a main compressor installed between low and high pressure gas mains, driven by a gas turbine, containing a surface heat exchanger placed after the main compressor and connected to a consumer heat through the liquid line and boiler 1}
    However, the known installation possesses. It has low thermodynamic efficiency due to the fact that the heat given off to the gas during compression is not used. In this case, the gas temperature after compression increases and, consequently, the heat losses in the gas line increase.
    The purpose of the invention is to increase the thermodynamic efficiency of the installation by the beneficial use of heat withdrawn from the gas during its compression.
    This goal is achieved by the fact that the installation for utilization outside the compression cycle of low-grade waste heat from a compressor station, including a main compressor installed between low and high pressure gas mains, is driven by

    In addition, the heating medium can be connected to the exhaust of the gas turbine or parallel to it, and to the heated one - in series with the surface heat exchanger, and the installation can be additionally equipped with kinematically connected steam turbine and auxiliary compressor and condenser, with the auxiliary compressor) installed in parallel the main between the low-pressure main and the surface heat exchanger; ohm, the boiler is connected to the gas turbine before and after the last, and heated Rede - to the steam turbine and condenser, forming with the latter a closed loop with the generation of steam in the boiler.
    The installation is also equipped with an additional cooling tower, to the heat exchange surface of which a condenser is connected through a cooling medium, and an additional heat exchanger connected via a heating medium to the boiler, and heated up to a liquid line above the surface heat exchanger;
    The surfaces of the main and additional cooling towers are combined in one case, and the boiler, additional heat exchanger, heat exchange surfaces of the main and additional cooling towers are connected to the surface heat exchanger.
    Figure 1 shows the installation, General view; figure 2 - installation with a boiler, podklychennym in the heating medium to the exhaust gas turbine; on fig.Z - the same, parallel to the gas turbine; figure 4 - the same, with parallel-connected compressors; on fig.Z - the same, the heat exchange surfaces of the cooling towers are spacing; they are in the same housing; 6 is the same, the heat exchange surfaces of the cooling towers have a common cooling system. The proposed installation includes low and high pressure gas lines 1 and 2, respectively, between which the main compressor 3 is installed and is driven by a gas turbine 4. The gas for the gas turbine is supplied from line 1 through line 5. After compressor 3, a surface heat exchanger 6 is installed, connected to the consumer 7 of heat through the main line 8 for a liquid, in which a circulation pump 9 is installed. Fluids through the cooling medium are connected heat exchange surfaces 1 O of the main cooling tower 11, which contains flat louvers 12 for adjusting the air draft inside it. The installation also contains a boiler 13, which can be connected to the exhaust 14 of the gas turbine 4 (FIG. 2) or parallel to the gas turbine 4 (FIG. 3 and heated in series with the surface heat exchanger 6 (FIG. 2)) and additionally equipped with a heating medium Kinamatiki connected steam turbine 15 and an auxiliary compressor} 6 and a condenser 17 (Fig. 4), the auxiliary compressor 16 being installed parallel to the main compressor 3 between the low pressure pipeline 1 and the surface heat exchanger 6, the boiler 13 for heating media It is connected to the gas turbine 4 before and after the last, and to the steam turbine 15 and the condenser, 17, on the heated medium, forming a closed loop I8 with the latter generating steam in a boiler 13.

    line 8, an additional heat exchanger 19 is installed, connected via heating medium to boiler 3, and heated to liquid line 8 after the surface heat exchanger a boiler 13, additional heat exchanger 6, heat exchange surfaces 10 and 20 of the respective main and additional cooling towers P and 21 are connected to surface heat exchange NIKOM 6 (fig.Z), line 8 and condenser 17 pipelines 22-24, respectively.
    During the operation of the installation, the low-pressure gas supplied from the low-pressure gas pipeline 1 is supplied to the main compressor 3 driven by the gas turbine 4. After compression in the main compressor 3, the gas with elevated temperature and pressure enters the high pressure pipeline 2.
    The compressed gas heated in the main compressor 3 is cooled in the surface heat exchanger 6 with water or another liquid, for example an antifreeze solution circulated in the liquid line 8. On the line 8, the heated fluid is pumped by the pump 9 to the heat consumer 7, which need not be located near the compressor station. It may be a communal heating system or industrial or agricultural heating. The heated coolant may flow into the heat exchanger surfaces of the 1 O tower of the cooling tower 11. This is necessary when the heat consumer consumes little heat, which is not enough to cool the compressed gas in the surface heat exchanger 6. The flow rate of the fluid can be regulated by means of flow control in the pipes 22-24.
    In addition, the invention allows to use more heat than is obtained from it when the compressed gas is cooled. In this case (FIG. 2) the cooling liquid of the surface heat exchanger 6 is supplied to the boiler 13 before it is supplied to the heat consumer 7.
    When connecting the boiler 13 through the heating medium parallel to the gas turbine 4, the heat generated in the boiler 13 when the gas is burned is supplied to the consumer 7 of heat together
    with heat received from a gas in a surface heat exchanger 6 (Aig.3), |
    If the heat output of the surface heat exchanger 6 is stable, the heat consumption of the heat consumer 7 is controlled by changing the heat output from the boiler 13 by changing the amount of the combusted gas. Thus, heat can be supplied to the heat consumer 7 even if the gas turbine 4 stops.

    but to burning gas. Steam, with one stool-15 connected in series with the surface, is directed to an additional heat exchanger 19, ac of the other side, into a steam turbine 15, which is kinematically connected with an auxiliary compressor 16. The outgoing steam from the steam turbine 15 is condensed in a condenser 17, the cooler of which is cooled in an additional cooling tower 21.
    The condensate formed in the additional heat exchanger 19 enters the condenser 17, and from it all the condensate formed enters to preheat the surface heat exchanger 6.
