Method for starting a once-through steam generator and the once-through steam generator for carrying out said method

摘要

The throughflow steam generator (1) has an evaporator throughflow heating surface (8) in a hot gas channel (6) through which gas can flow approximately horizontally with a number of steam generator tubes (12) in parallel and a superheating surface (20) following the evaporator throughflow heating surface with a number of superheating tubes (22) in parallel. The evaporation end point of the flowing medium is predominantly in the superheating tubes. An independent claim is also included for the following: (a) a horizontal throughflow steam generator.
