Abstract

Procedure for the regulation of a forced circulation steam generator, where both the flow of the feed water as well as the quantity of fuel and air are influenced by a main signal depending on the temperature of the working medium and by an auxiliary signal that it depends on the temperature of the working medium which - seen in the direction of the working medium current - is taken from the temperature of the first mentioned working medium, characterized in that a temperature of steam that is in the final superheat zone and that the main signal is subjected to a Proportional, Integral, and Differential transformation and the auxiliary signal to a Proportional-Differential transformation.
