Definitions

• the invention applies to the generation of mechanical - electrical power, the joint generation of mechanical power and heat, as well as other technological plants, e.g. the petrochemical industry, the food industry, and the gas generation.
• thermodynamic laws it is proportional to the nature of the substance - its specific thermal capacity, " its -temperature before the thermal machine - the turbine - and the pressure, ratio before and ; after the machine. ; :: . . :
• the maximum cycle pressure - at the turbine inlet - is limited by the properties of the material the machine is manufactured of and which may be used for the particular temperature.
• the pressure at the machine outlet is selected so that the condensation in the steam section from the mixture with carbon dioxide would have its course in the following heat transformer at pressure higher than the ambient one - the atmospheric pressure. This eliminates the necessity of suction off the carbon dioxide from the heat transformer, which requires certain energy, but it may be only relieved from the cycle.
• At least one more steam generator may be put before the heat transformer.
• the steam-gas mixture at the primary side is cooled while at the secondary side overheated HP steam is generated and supplied into the turbine. It works at a pressure and temperature steam level different from that of the original generator and the steam transformer. It is put between the original steam generator and the heat transformer admission part.
• the pressure and temperature of the generated steam conform to those of the steam-gas mixture, and decrease in the direction of its flow.
• the steam temperature and pressure at the outlet, of the heat transformer and the individual heat generators are selected so as to allow the most effective utilization of the energy contained in the steam-gas mixture at the turbine outlet.
• the steam generated in the steam generators and the heat transformer is pipelined into the multi-pressure section of the gas-steam turbine, Here it increases its volurne. as. far as the pressure in the condenser where it condenses. Using a condensate pump, the condensate is discharged from the condenser back into the cycle.
• the steam generators and the heat transformer mentioned above may be placed in one body where steam of different pressure is generated.
• the attached figure shows a simplified scheme of the emissionless thermal cycle with a gas- steam turbine, a steam generator and a heat transformer.
• the enclosed figure shows a scheme of the emissionless cycle with a one-stage steam generator and a heat transformer, consisting of the steam-gas mixture generator 7, connected by the steam-gas mixture piping 16 with the gas-steam turbine I 1 the outlet branch of which is connected with the steam generator (S 1 and the heat-transformer 6, .
• the one-stage steam generator 5 may be replaced with a multi-stage one, producing multi-pressure steam admitted into the multi-stage steam turbine.
