Abstract

La presnete invención se refiere a un sistema de seguridad mejorado para un molino pulverizador de carbón que comprende: medios para determinar la cifra de cambio del nivel de monóxido de carbono y otros gases combustibles en el molino pulverizador de carbón y establecer señales indicativa de mismo; medios para comparar dicha señal proveniente de dichos medios de detección con un punto de colocación de señal indicativo de un cambio de cifra potencialmente peligros del nivel de monóxido de carbono y otros gases combustibles en el molino pulverizador de carbón y establecer una primera señal de control de los mismos, y medios de alarma que responden a dicha primera señal de control para indicar una condición potencialmente peligrosa en el molino pulverizador de carbón.The present invention relates to an improved safety system for a coal pulverizing mill comprising: means for determining the amount of change in the level of carbon monoxide and other combustible gases in the coal pulverizing mill and establishing indicative signs thereof; means for comparing said signal from said detection means with a signal placement point indicative of a potentially dangerous change in the level of carbon monoxide and other combustible gases in the coal pulverizing mill and establishing a first control signal for the same, and alarm means that respond to said first control signal to indicate a potentially dangerous condition in the coal pulverizer mill.
