Embodiment Construction

[0029] Said single figure shows a cylindrical water supply container or tank 1 lying horizontally and in which there is supply water 2 at the bottom and saturated steam 3 in the area formed above it. In the water supply tank 1 , the area filled with the supply water 2 reaching the liquid bath surface 4 is hereinafter referred to as the water supply area 5 , and the area formed above it is hereinafter referred to as the steam area 6 of the water supply tank 1 . In the water supply area 5, degassed water supply for the water / steam cycle of a connected solar thermal power plant (not shown) is supplied and prepared. The water supply tank 1 is connected to the water / steam circuit via a water supply line 7 whereby the water / steam circuit is supplied with degassed supply water 2 in the direction indicated by the arrow in the pipe 7 .

[0030] Arranged above the steam area 6 on the water supply tank 1 is a vertical cylindrical deaerator 8, which in the illustrated embodiment of the in...

Abstract

The invention relates to a feed water degasifier comprising a degasifier (8) with a feed water tank (1) connected thereto, said components being integrated into the water / steam cycle of a solar thermal power station that has a heat transfer medium circuit with an associated water / steam cycle. The aim of the invention is to provide a solution, which in terms of the heating and control process provides a less complex way of supplying the degasifier with heating steam in comparison with prior art. To achieve this, at least one additional evaporator (11), which has a line connection (12) on the water side to the feed water region (5) of the feed water tank (1) and a line connection (13) on the steam side to the steam region (6) of the feed water tank (1), is allocated to the feed water tank (1).

Description

technical field [0001] The present invention relates to a water supply deaerator comprising a deaerator with an associated water supply tank, said deaerator and water supply tank being incorporated into the water / steam cycle of a solar thermal power plant comprising Heat transfer medium circuit for distributed water / steam cycle. The invention also relates to a solar thermal power plant with such a feed water deaerator, and to a method of using the degasser in the water / steam cycle of a solar thermal power plant for supply water degassing and / or A method of heating water. Background technique [0002] A solar thermal power plant generally has a heat transfer medium circuit and a water / steam cycle coupled thereto via a heat exchanger, has a steam turbine arranged therein for converting thermal energy into mechanical energy, and has an associated generator for generating electrical energy. This involves, for example, the use of solar elements in the form of parabolic mirrors,...
