Abstract

Unos perfeccionamientos en los circuitos de calefacción para generadores de vapor de presión variable, caracterizados por comprender las fases a establecer la circulación en el generador para cargas normales mediante la bomba de alimentación del generador, siendo la evaporación en el mismo igual a la velocidad de circulación, varias la presión en el interior del generador en proporción a la carga, llevar a cabo la evaporación en la envolvente del horno para cargas más bajas solamente hasta una mezcla vapor-líquido, separar las partes vapor-líquido de dicha mezcla, recircular la parte del líquido de la mezcla hacia la envolvente del horno para dichas cargas bajas, proporcionando a la circulación natural la fuerza de impulsión para la recirculación por lo menos en parte y convertir el generador de flujo recirculante a flujo directo y viceversa, sustancialmente a la carga y presión para las cuales se presenta poca o ninguna fuerza de impulsión por circulación natural.
