<p>A combined radiant and convection oven (100) controls the rate at which heat is transferred to an object (103) being dried within the oven by varying the flow rate of convection air delivered to the oven's heating chamber (114). The radiating surfaces (191, 192) within the oven (100) are heated by a novel arrangement of longitudinally extending ducts (177, 179), each duct associated independently with a different radiating surface.</p> |
