Abstract

Caldera de recuperación de calor perdido para intercambio de calor de un gas de proceso relativamente caliente con un medio refrigerante, que comprende - una parte de envuelta, - al menos dos placas de tubos, - una pluralidad de tubos de intercambio de calor, - al menos un tubo de derivación, - una sección de intercambio de calor confinada por dicha parte de envuelta y dichas al menos dos placas de tubos, - una sección de entrada de gas de proceso, - una sección de salida de gas de proceso, - al menos una entrada de medio refrigerante, - al menos una salida de medio refrigerante, en donde, en uso, el gas de proceso relativamente caliente entra en los tubos de intercambio de calor y en el al menos un tubo de derivación en la sección de entrada de gas de proceso, y circula por la sección de intercambio de calor, en donde al menos el gas de proceso que circula por los tubos de intercambio de calor está en intercambio de calor indirecto con el medio refrigerante y sale en la sección de salida de gas de proceso, y en donde dicha caldera de recuperación de calor perdido comprende, además, una válvula de control y un colector de gas de proceso de salida, estando la caldera de recuperación de calor perdido caracterizada, además, por que dicha válvula de control está capacitada para controlar la corriente volumétrica del gas de proceso que circula por dicho colector de gas de proceso de salida, y el colector de gas de proceso recoge al menos una parte del gas de proceso que sale del al menos un tubo de derivación y el gas de proceso enfriado que sale de una parte de los tubos de intercambio de calor.

intercambiado en calor es más baja que la temperatura de la mezcla del gas de proceso derivado y el gas de proceso intercambiado en calor que sale de la salida 138 de gas de proceso, la válvula de control puede variar la temperatura del gas de proceso que sale de la sección de salida de gas de proceso dentro de un intervalo entre la temperatura del gas intercambiado en calor y el gas de derivación mezclado. O lo que es más importante, la válvula
5 de control puede mantener la temperatura del gas de proceso que sale de la sección de salida de gas de proceso en un cierto nivel, aun cuando la temperatura del gas de proceso intercambiado en calor varíe debido a, por ejemplo, un intercambio de calor indirecto reducido a causa de, por ejemplo, el ensuciamiento de los tubos de intercambio de calor.
La figura 2 muestra la caldera de recuperación de calor perdido de la figura 1 con las temperaturas anotadas. Las 10 temperaturas tienen las relaciones siguientes:
t1  t3 > t4 > t2
