    ammonia is released as condensate. Exhaust gases through T 16 are vented to P 14. Part of the gas stream with non-substituted components is withdrawn to T 22, where it is biased with residual gases U 11 and device 10, after which their mixture is compressed in the combustion chamber 21 turbines 18.

    connected to the combustion chamber 21, connected on one side through the pipeline 22 of combustible gas to the installation 3 for the production of chemical raw materials with combustible gas, and on the other hand to the compressor 19. The pipeline 22 of combustible gas is connected through a cleaning device, made in the form of gas washing installation 23, to the crude gas pipeline 24 connecting the coal gasification unit 4 with the conversion unit 9, as well as to the pipelines 25 of the air decomposition unit 5, which also has oxygen removal lines 26 into the gas a generator 6. A waste heat boiler 28 is connected to the waste gas line of the gas turbine 18 28. The waste heat boiler 29 is connected to the steam turbine 30 of the steam turbine power unit 3, the steam turbine 30 consists of
    31 high pressure (CWD) and parts
    32 low pressure (PND). It is connected to the generator 33. After the PND 32, the capacitor 34, the condenser pump 35, the feed water tank 36 and the feed water pumps 37 and 38 are installed in series.
    The power plant works as follows.
    The gas generator 6 is supplied with coal and oxygen through line 26 from the connected air decomposition unit 5. In addition, process steam is introduced into the gas generator 6 coal. Coal.gasses with oxygen and process steam in

    Clean gas containing carbon monoxide and hydrogen. This crude gas is cooled in a heat exchanger 7 connected to a gas generator 6 coal. The heat released in the heat exchanger 7 is used to produce steam. Then, the unpurified gas is released in the dust removal device 8 from the gas supplied to it by water from dust particles that are in it. Depending on the mode of operation of the power plants, the crude gas subjected to such purification may be supplied to different parts of the combustion chamber 21 of the gas-turbine I8 and the subsequent conversion steps in unit 3 for the production of chemical raw materials.

    Primary gas is primarily carried out through a conversion unit 9. In it carbon monoxide contained in the crude gas, with the help of water pre-25, is formed into hydrogen and carbon dioxide. Carbon dioxide and the hydrogen sulfide contained in it are removed in a sequentially connected gas cleaning device 10 according to a known method. The gas thus purified, containing essentially only hydrogen and, depending on the degree of conversion of carbon monoxide to a more or less severe degree, is cleaned in the decomposition unit 11 using the liquid nitrogen supplied from the decomposition unit 5 via the pipeline 25 from all other gases with the exception of hydrogen, and at the same time g is also enriched with nitrogen. At the same time, at the outlet of the plant 1 1 is decomposed-, the NIN of the gas must be set to a 3: 1 ratio of hydrogen to nitrogen. This synthesis gas is supplied to plant 12 for ammonia synthesis. There, it is first of all compressed with gas-i compressor 13 to process pressure and then introduced into ammonia synthesis reactor 14. Gases leaving ammonia synthesis reactor n 14 and incompletely converted containing ammonia are cooled in a sequentially connected gas separator 15. In this case, ammonia is discharged as condensate. The flue gases through the recirculation pipe 16 are discharged to the ammonia synthesis reactor 14. Part of the reduced waste gases

    as a so-called cleaning gas with non-substituted gas components, 22 combustible gases are diverted into the pipeline and, together with the crude gas, are combusted in the combustion chamber 21 of the gas turbine 18. The residual gases of the gas decomposition unit I1 and the gas cleaning device 10 are discharged The vehicle is in the pipeline 22 of combustible gas and is combusted with the raw gas. The combustible waste gases of the gas turbine 18 are conducted through the waste heat boiler 28 and give up most of their heat there. In the boiler 28, fresh steam is generated from the water supplied by the feedwater pump 37. This steam, together with the steam supplied to the heat exchanger 7, is supplied to the steam turbine 30. From the respective steps of the parts pressure. Steam turbine 30 is used to extract process steam, which is necessary for the operation of the gas generator 6 coal and for various conversion stages. The steam used in the steam turbine 30 is condensed in the condenser 34 and supplied as a feed water through a condensate pump 35 to the feed water tank 36.
    When using coal with a high content of sulfur, it is recommended to install the gas-washing unit 23 into the combustible gas pipeline 22 leading from the dust removal device 8 to the gas turbine combustion chamber 2 in order not to exceed the allowable amount of sulfur emissions in the gas turbine 18. For this, it is sufficiently simple to install, by means of which hydrogen sulfide is diluted using a suitable solvent.
    When using coal with significant sulfur content, it may also be advantageous to supply cooled raw gas leaving the dust removal devices 8 from the gas, partially bypassing the conversion unit 9 of the gas cleaning unit 10 and decomposing the unit II nor gas. As a consequence, gas decomposition unit 11 produces substantially more carbon monoxide and less hydrogen. Thereby, more of the carbonaceous gas containing carbon monoxide can be supplied to the combustion chamber 21. For this in installation 12 for syn5130991
