Sistemas de agua de refrigeración

En una central termoeléctrica se requiere un sistema de refrigeración para convertir el vapor utilizado después de la turbina en condensado líquido (condensador). Para el funcionamiento económico del sistema de refrigeración se requiere un complejo tratamiento químico del agua. Las torres de refrigeración consumen altos costes operativos y de planta, y requieren un mantenimiento intensivo para evitar costosos tiempos de inactividad de toda la central eléctrica. Las principales dificultades son el escalado, la corrosión y el crecimiento biológico de algas y bacterias.

Hechos clave de la aplicación

Aplicación

3 aplicaciones (1.ª prueba de oxígeno disuelto DO, 2.ª prueba del valor de pH y conductividad, 3.ª prueba de conductividad) en varios puntos de medición

Área

Centrales eléctricas en operación combinada

Requisitos principales

Formación de incrustaciones en las calderas, corrosión y crecimiento biológico causado por algas y bacterias.
