Description
Emissionless Cycle with Steam Generator and Heat Transformer
Scope of Technology
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.
Present State of Technology
In connection with the increasing problem of the warming of our planet, there is an endeavor to reduce the amount of carbon dioxide and other dangerous substances being released into the atmosphere. New technologies are under development the working substances of which are not the air but pure substances, e.g. fuel, oxygen, water, or carbon dioxide. Abroad, they are also called the CES systems. One of them is the emissionless cycle with a gas-steam turbine, the description of which can be found in the invention application No 2001 3331. Here, the fuel and oxygen are combusted at high pressure and temperature. After this, water is injected into the generated combustion product, generating thus a mixture of superheated steam and carbon dioxide - the steam-gas mixture (hereinafter only SGM) - which enters the thermal machine - the turbine.
Only part of the thermal power conveyed into cycle through the working substance . pan be used for converting into mechanical power. According to the 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.
These limitations determine the pressure ratio of the HP section of the gas-steam turbine, which is one of the main reasons. why not all the thermal power contained in the steam-gas mixture at the outlet the HP module can be fully utilized. If the thermal efficiency of the cycle is to be increased, then by increasing the temperature of the steam-gas mixture at the inlet into the turbine HP section the temperature at its outlet increases in due proportion.
Subiect-matter of Invention
The problems mentioned above are partly solved by the emissionless cycle, with a steam generator and a heat transformer, the principle of which consists in the fact that the outlet branch of the HP turbine is connected using a steam-gas mixture piping with the primary side of the steam generator, and then with the heat transformer, while the secondary side of the steam generator is connected to-the step-up pump, and by the HP steam piping to the HP steam module.
If the temperature of the gas-steam mixture at the turbine outlet is high, at least one more steam generator may be put before the heat transformer. Here 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.
