Title: Dryer appliances including an air circulation duct

Abstract

A dryer appliance including an air circulation duct is provided herein. The dryer appliance may also include a cabinet, a drum, an air handler, and a heat exchange section. The air circulation duct may define a recirculation loop with the drum. The air circulation duct may define a drum air inlet upstream from the drum and a drum air outlet downstream from the drum. The air circulation duct may further define a predetermined leakage port in fluid communication between the recirculation loop and the interior volume of the cabinet. The air handler may be disposed along the air circulation duct in fluid communication between the drum air outlet and the drum air inlet. The heat exchange section may be disposed along the air circulation duct in thermal communication with air within the recirculation loop.

A burner for use in a combustion system of a heavy-duty industrial gas turbine includes a fuel/air premixer having an air inlet, a fuel inlet, and an annular mixing passage. The fuel/air premixer mixes fuel and air into a uniform mixture for injection into a combustor reaction zone. The burner also includes an inlet flow conditioner disposed at the air inlet of the fuel/air premixer for controlling a radial and circumferential distribution of incoming air. The pattern of perforations in the inlet flow conditioner is designed such that a uniform air flow distribution is produced at the swirler inlet annulusmore » « less

Open-loop heat-recovery dryer

Patent TeGrotenhuis, Ward Evan

A drying apparatus is disclosed that includes a drum and an open-loop airflow pathway originating at an ambient air inlet, passing through the drum, and terminating at an exhaust outlet. A passive heat exchanger is included for passively transferring heat from air flowing from the drum toward the exhaust outlet to air flowing from the ambient air inlet toward the drum. A heat pump is also included for actively transferring heat from air flowing from the passive heat exchanger toward the exhaust outlet to air flowing from the passive heat exchanger toward the drum. A heating element is also includedmore » « less
