| description | The present invention increases the operation efficiency of a soot blower while suppressing a change in the steam temperature of a heat transfer tube. This soot blower control system is provided with: a soot blower (30) that jets steam onto the surface of a heat transfer tube (6); an inlet temperature sensor (20d) that detects the steam inlet temperature (Tin) of the heat transfer tube; an outlet temperature sensor (20e) that detects the steam outlet temperature (Tout) of the heat transfer tube; and a controller (100). The soot blower control system is characterized in that the controller calculates a temperature change value (dT) which is the difference between a first temperature difference (ÎT1) and a second temperature difference (ÎT2), which are differences between the steam inlet temperature and the steam outlet temperature at a first time point and a second time point, respectively, during operation of the soot blower and determines an operation interval of the soot blower so as to keep the temperature change value within the range of a target value.
La presente invención aumenta la eficacia de operación de un soplador de hollín mientras suprime un cambio en la temperatura del vapor de un tubo de transferencia de calor. Este sistema de control de soplador de hollín se proporciona con: un soplador de hollín (30) que rocía vapor sobre la superficie de un tubo de transferencia de calor (6); un sensor de temperatura de entrada (20d) que detecta la temperatura de entrada de vapor (Tentrada) del tubo de transferencia de calor; un sensor de temperatura de salida (20e) que detecta la temperatura de salida de vapor (Tsalida) del tubo de transferencia de calor; y un controlador (100). El sistema de control de soplador de hollín se caracteriza porque el controlador calcula un valor de cambio de temperatura (dT) que es la diferencia entre un primer diferencial de temperatura (?T1) y un segundo diferencial de temperatura (?T2), los diferenciales de temperatura están entre la temperatura de entrada de vapor y la temperatura de salida de vapor en un primer punto de tiempo y un segundo punto de tiempo, respectivamente, durante la operación del soplador de hollín, y determina un intervalo de operación del soplador de hollín para mantener el valor de cambio de temperatura dentro del rango de un valor diana. |
