  • Method for operating a steam power plant, particularly a steam power plant in a power plant for generating at least electrical energy, and corresponding steam power plant
    Patent number: 7886538
    Abstract: The invention relates to a method for operating a steam power station and a power plant as well as a corresponding steam power station. According to the invention, essentially all of the water that is drained from at least one pressure stage of the steam power station is collected, stored, and recirculated into the water circuit of steam power station.

  • Method of using a test liquid for checking the efficiency of electrical power station components
    Patent number: 5996399
    Abstract: The invention teaches a method for using a test liquid to simulate the effects of a coolant condensate on an electrical power station component in the event of an accident with an uncontrolled escape of coolant condensate, in which a film is formed on a surface of the power station component and then a resistance test of the power station component is performed. A test liquid formed of polyglycol ether which has a content of between 0.01 and 0.5 weight % dissolved in deionized water, a conductivity between 1 and 6 .mu.S/cm at room temperature, and a surface tension up to 50 mN/m at room temperature is provided. A power station component is coated with a film of the test liquid. A resistance check of the coated power station component is then performed.
