Abstract
Un método para medir cambios de masa de un banco de intercambiadores de calor (1, 2, 3) o los intercambiadores de calor de este de una caldera de vapor, cuyo intercambiador de calor (4) se encuentra apoyado por medio de varillas de suspensión (7) a vigas de apoyo (5, 8) por encima de la caldera de vapor, caracterizadas porque a lo menos una varilla de suspensión (7) de a lo menos un intercambiador de calor (4) se encuentra conectada con un elemento de medición inferior (9) y un elemento de medición superior (10), y los cambios de la longitud de medición (X) entre los elementos de medición (9, 10) son medidos por medio de un instrumento de medición (15) conectado entre los elementos de medición (9, 10) para medir los cambios de masa del intercambiador de calor (4). Preferiblemente, el instrumento de medición (15) se fija entre los elementos de medición (9, 10) y el cambio en la longitud de medición (X) es medido por la deformación del instrumento de medición (15). Preferiblemente, un elemento de conexión (11) que es paralelo a la varilla de suspensión (7) se encuentra entre los elementos de medición (9, 10), cuyo elemento de conexión (11) transmite el cambio en la longitud al instrumento de medición (15). Un elemento elástico (16) se encuentra conectado entre el elemento de medición (9) y el elemento de medición superior (10).
