A recently granted patent (Publication Number: US11906245B2) discloses a method for controlling air flow through an electric heater mixing plenum in various systems, including air recirculation and drying systems. The method involves adjusting the positions of inlet and outlet dampers in different chambers of the plenum to regulate air flow based on monitored properties such as temperature, pressure, and humidity. By controlling the dampers and monitoring the process air properties, the system can optimize energy efficiency and performance. Additionally, the method includes provisions for adjusting the dampers based on electric energy costs and fossil fuel costs, allowing for cost-effective operation by modifying air flow through the chambers accordingly.

Furthermore, the patent details the specific configurations and operations of the electric heater mixing plenum in different scenarios, such as when shutting down the electric air heater or increasing fossil fuel input into a combustion system. The method also includes monitoring and adjusting humidity levels in the process air to further optimize the system's performance. By implementing these control strategies, the electric heater mixing plenum can effectively manage air flow, temperature, and energy consumption in various applications, ensuring efficient operation and cost savings. Overall, the patented method offers a comprehensive approach to controlling air flow in electric heater mixing plenums, enhancing the functionality and effectiveness of systems utilizing such technology.
