  • Pulse-jet valve performance monitoring system and method
    Patent number: 10933362
    Abstract: An system includes a fabric filter, an air supply system, a pulsing valve that is coupled to the air supply system and is configured to generate a statistical pulse of air that is directed to the fabric filter, an air flow monitor that is configured to monitor a flow of air associated with the statistical pulse of air, and a valve controller that is coupled to the air flow monitor that is configured to generate a performance signature for the pulsing valve based on the flow of air that was monitored.
