    摘要: The fluid flow rate from a drain tank (32) is regulated by cooperatively modulating first and second valves (42, 44) arranged in parallel flow relation to allocate fluid flow to first and second fluid sinks (38, 40).
    First and second parallel acting signal generators (50, 52) detect the fluid level in the drain tank (32) and generate fluid level indicator signals. The first signal generator's signal is normally transmitted to the first valve (42) which modulates in response thereto to maintain the desired drain tank fluid level. The second signal generator (52) normally provides a drain tank level indication signal to the second valve (44) which modulates for signals indicative of drain tank fluid levels greater than a predetermined height. Signal monitors (66, 68) provide means for detecting erroneous signals generated by the first and second signal generators (50, 52). If an erroneous signal, as indicated by a signal being out of a predetermined range, from one signal generator is monitored, transmission of that signal to its respective valve is obstructed and the other signal generator's signal is transmitted to both valves (42, 44).

    摘要: A steam power plant is suggested having, parallel to the preheater passage (VW1 to VW4), a heat reservoir (25) which is loaded with preheated condensate in weak-load times. This preheated condensate is taken from the heat reservoir (25) for generating peak-load and inserted downstream of the preheater passage into the condensate line (19.2) resp. the feed water container (8). Thus it is possible to quickly control the power generation of the power plant in a wide range without significantly having to change the heating output of the boiler of the steam generator (1). A steam power plant equipped according to the invention can thus be operated with bigger load modifications and also provide more control energy.

A solar power system according to the present invention includes: a heat collection apparatus (2, 4) ; a steam turbine (5), a power generator (16); a superheated steam supply line which supplies the steam turbine with superheated steam generated by the heat collection apparatus; a water supply line which condenses the steam expelled from the steam turbine into water and supplies the condensed water to the heat collection apparatus; a heat storage device (8) which has a heat storage medium; a first line which branches from the superheated steam supply line and which supplies the heat storage device with the superheated steam flowing through the superheated steam supply line; a second line which branches from the water supply line and which supplies the heat storage device with the water flowing through the water supply line; and a third line which supplies the steam turbine with superheated steam generated by the heat storage device. The heat storage device stores the heat of the superheated steam which has flowed through the first line in the heat storage medium, and heats the water which has flowed through the second line with the heat storage medium to thereby generate the superheated steam.
