Abstract

En las calderas presurizadas donde se quema combustible fósil para generar vapor, se utilizan Ventiladores de Tiro Forzado (VTF) para suministrar el oxígeno necesario para quemar el combustible en la cámara de combustión (horno); los ventiladores cuentan con dos compuertas reguladoras, tipo persianas, para manipular el flujo de aire. La característica de trabajo de los VTF es no lineal, es decir no existe correspondencia proporcional entre el flujo de aire que entrega el ventilador con la posición que ocupan las compuertas de regulación, lo que hace inestable la regulación automática de la Combustión; la solución propuesta consiste en incorporar un bloque "linealizador" en la senal de realimentación de posición de las compuertas, ajustado de forma que la senal de posición de las compuertas (entrada del regulador de posición) sea proporcional al flujo de aire que entrega el ventilador, con lo que se logra la correspondencia lineal entre la senal de mando del regulador de la combustión y el flujo de aire que entrega el VTF, necesaria para lograr la regulación automática de la Combustión.In pressurized boilers where fossil fuel is burned to generate steam, forced draft fans (VTF) are used to supply the oxygen necessary to burn the fuel in the combustion chamber (furnace); The fans have two regulating gates, type blinds, to manipulate the air flow. The working characteristic of VTFs is non-linear, that is, there is no proportional correspondence between the air flow that the fan delivers with the position occupied by the regulation gates, which makes automatic combustion regulation unstable; The proposed solution consists of incorporating a "linearizer" block in the gate position feedback signal, adjusted so that the gate position signal (position regulator input) is proportional to the air flow delivered by the fan , which achieves the linear correspondence between the control signal of the combustion regulator and the air flow delivered by the VTF, necessary to achieve automatic combustion regulation.
