Experience with using the technology of starting modes of power units equipped with a built-in assembly

Papers on the operating modes of the starting built-in assembly used in the once-through boilers of 150-, 200-, 300-, and 500-MW power units are reviewed. It is shown that this assembly does not meet the requirements for separating steam-water medium into steam and water that are placed on it, this resulting in degraded reliability of the heating surfaces situated downstream of it. Proposals for solving these problems are given.
