Steam turbine plant for thermal power plant, and methods of operating a steam turbine plant for thermal power plant

摘要

Steam turbine plant for thermal power plant, with– a steam turbine (12a) with a steam inlet (14a), for live steam, and a steam outlet (16a) for exhaust steam, for the conversion of energy of the steam into mechanical output, and– a together with the steam turbine (12a) in a water - steam - circuit and on the one hand with the vapor outlet (16a) of the steam turbine (12a) and, on the other hand, with the steam inlet (14a) of the steam turbine (12a), the steam which is connected to provide a direction (20a, 22a, 24a, 26a, 28a, 30a), the with thermal energy from a force of the tool position process heat is supplied from the exhaust steam from the steam turbine (12a) live steam for the steam turbine (12a) to produce,characterized by– a reactor (40a) with a reaction chamber (42a) to the hydrothermal carbonization of biological residues,– Energy transfer means consist (44a, 46a, 48a, 50a, 52a) for the transmission of thermal energy from the carbonization process into the water - steam - circuit, wherein the energy transfer means consist (44a, 46a, 48a, 50a, 52a) on the steam providing a direction (20a, 22a, 24a, 26a, 28a, 30a) at least one branch (44a) via a line (46a) with a to the heat loss from the reaction chamber (42a) of the reactor (40a) heat exchanger provided (48a) which is connected through a return pipe (50a) with a einzweigung (52a) at another point of the water - steam - circuit is connected, and– further energy transfer means consist (60a, 62a, 66a; 70a, 72a, 74a, 80a, 82a) for the transmission of thermal energy from the water - steam - circuit in the reaction chamber (42a) of the reactor (40a), in order to initiate the carbonization process, the further energy transfer means consist (60a, 62a, 66a; 70a, 72a, 74a, 80a, 82a) on the steam turbine (12a) in the course between the steam inlet (14a) and the steam (16a) at least a vapor tap (60a; 70a, 72a) and / or on the water - steam - circuit branch a freshly steam via a steam line (62a; 74a) to the reactor (40a) is connected.
