Abstract
Procedimiento de mando de una caldera con circulación forzada, en particular para una turbina de vapor, comprendiendo la caldera por lo menos un primer intercambiador de calor (10) cuya entrada está conectada a un conducto de alimentación de agua (18) y cuya salida está conectada, a través de una válvula de regulación (30), o bien a la entrada de un segundo intercambiador de calor (12), cuya salida está conectada a la turbina de vapor, o bien directamente la turbina de vapor, caracterizado porque: - durante la fase de puesta en marcha, la válvula de regulación (30) está cerrada, - mientras el fluido a la salida del primer intercambiador (10) sea un fluido difásico constituido por una mezcla de agua y de vapor, se provoca la condensación de este fluido difásico en agua líquida, por mezcla de dicho fluido con agua de alimentación y sin separación previa de las fases gaseosa y líquida de dicho fluido, siendo la cantidad de agua de alimentación necesaria para la condensación de dicho fluido regulada con respecto a la temperatura (42) del fluido corriente abajo del punto de unión del conducto de salida (24) y de un conducto en bypass (38) entre el conducto de entrada (18) y el conducto de salida (24) del primer intercambiador (10), de manera que durante la fase de puesta en marcha, esta temperatura permanece inferior a la temperatura de saturación; - cuando el fluido a la salida del primer intercambiador (10) es vapor puro, se abre progresivamente la válvula de regulación (30).
