Abstract

MEDIANTE UN SOLO DETECTOR DE TEMPERATURA (7) COLOCADO EN EL FLUJO DE DESCARGA DE LOS PRODUCTOS DE COMBUSTION POR LA ENTRADA DE AIRE (5) DEL TIRO (3), SE MIDEN LAS VARIACIONES DT/DT DE TEMPERATURA DEL DETECTOR RESPECTO DEL TIEMPO, Y LA MEDIDA INSTANTANEA DE LA TEMPERATURA T DE LOS PRODUCTOS DE COMBUSTION DESCARGADOS, ASOCIADOS A LA MEDICION DE LA CORRIENTE DE LA ELECTROVALVULA DE REGULACION PARA QUE LA PUESTA EN SEGURIDAD NO INTERVENGA MAS QUE SI LA MEDICION DE LA TEMPERATURA ES SUPERIOR A UN UMBRAL PREDETERMINADO QUE CORRESPONDE A LA CORRIENTE DE DICHA ELECTROVALVULA. APLICACION EN LOS APARATOS DE POTENCIA VARIABLE.THROUGH A SINGLE TEMPERATURE DETECTOR (7) PLACED IN THE DISCHARGE FLOW OF COMBUSTION PRODUCTS BY THE AIR INLET (5) OF THE SHOT (3), THE DT / DT TEMPERATURE VARIATIONS OF THE DETECTOR ARE MEASURED, AND THE INSTANT MEASUREMENT OF THE TEMPERATURE T OF THE DISCHARGED COMBUSTION PRODUCTS, ASSOCIATED WITH THE MEASUREMENT OF THE ELECTROVALVE REGULATION CURRENT SO THAT THE SAFETY SETTING DOES NOT INTERVENE MORE THAN IF THE TEMPERATURE MEASUREMENT IS MORE THAN A PREDETERMINE THRESHOLD TO THE CURRENT OF SUCH A SOLENOID VALVE. APPLICATION IN VARIABLE POWER DEVICES.
