Abstract
In order to create a process for using solar energy in a gas and steam power station, which incorporates a gas turbine circuit and a steam turbine circuit for converting thermal energy into mechanical work, whereby a compressed gaseous heat carrier which has been heated is fed to a gas turbine in the gas turbine circuit and waste gases from the gas turbine are used to generate steam, which is fed to a steam turbine in the steam turbine circuit, and whereby this process has a high efficiency rate for converting thermal energy into mechanical work and makes optimum use of the solar energy, it is proposed that thermal energy be supplied to the heat carrier in the gas turbine circuit by means of solar radiation.

A process for using solar energy in a gas and steam power station, which incorporates a gas turbine circuit and a steam turbine circuit for converting thermal energy into mechanical work, comprising the steps of:
- feeding a heat carrier in the gas turbine circuit through a solar collector installation in order to absorb thermal energy by means of solar radiation, wherein the solar collector installation has channel collectors and wherein the channel collectors are arranged in parallel, whereby the heat carrier is divided to flow through several channel collectors,
- feeding a compressed gaseous heat carrier which has been heated to a gas turbine in the gas turbine circuit,
- using waste gases from the gas turbine to generate steam, and
- feeding the steam in the steam turbine circuit to a steam turbine.
A gas and steam power station for converting thermal energy into mechanical work, which is used in particular for generating electric current, comprising:
- a gas turbine circuit;
- a combustion chamber situated in the gas turbine circuit;
- a steam turbine circuit, wherein a compressed gaseous heat carrier which has been heated is fed to a gas turbine and wherein waste gases from the gas turbine are used to generate steam, which is fed, in the steam turbine circuit, to a steam turbine;
- and
- a solar collector installation, through which the gaseous heat carrier is fed for the purpose of absorbing thermal energy by means of solar radiation,
- wherein the solar collector installation is situated in the gas turbine circuit,
- wherein the solar collector installation has channel collectors, and
- wherein the channel collectors are arranged in parallel, so that the heat carrier in the solar collector installation can be divided between several channel collectors.
