Abstract
A solar heating system for assisting flue curing of Virginia tobacco leaf was studied. The equipment consisted of a brick and mortar tobacco curing barn of 3.6 m/sup 3/ volume. The solar air heater of 2.8 m/sup 2/ was a non-focus type, made from corrugated galvanized stel sheet coated with flat-black paint. The collector had a single glass cover on top and a 25 mm layer of styrofoam at the bottom. Electrical heating was utilized inside the bar to simulate the main heat source. The system under study had no thermal storage, therefore it was extremely difficult to regulate the temperature inside the barn precisely. Consequently, the solar assisting mode is not recommended during the yellowing stage of curing where very precise temperature control is required. Utilization of solar energy during other stages of curing showed a saving of the main conventional energy up to 33 to 15 percent. The average thermal efficiencies of the collector varied from 70 percent at high flow rate to 67 percent at low flow rate. 6 references.
