| 摘要 |
The invention relates to a heat exchanger for generating a steam flow for a solar-thermal power plant, comprising a casing for accommodating a casing-side fluid, and having pipes extending inside the casing for a pipe-side fluid, wherein the heat is transmitted via the pipes from the pipe-side fluid to the casing-side fluid. The casing-side fluid is water, and the pipe-side fluid is a thermo oil or salt. The invention allows for an increase of the startup gradients and the alternating load gradients, thus increasing the availability of the power plant. Furthermore, a higher operational safety can be achieved. |
