LABORATORY TESTING OF RADIANT GAS BURNERS AND ELECTRIC INFRARED EMITTERS

A project focusing on industrial infrared technology was carried out at Hydro-Québec's LTEE laboratory 1], The project required the optimization and use of a special test facility. Seven electric emitters and seven radiant gas burners typically used in the textile and pulp and paper industries were evaluated. Three types of experiments were carried out, providing four types of information: radiant flux maps, radiant efficiency evaluation, transient behavior characterization, and spectral emission characterization. The apparatus and the experimental procedures are described. Results are discussed and are presented in the form of tables and graphs. As the procedure and instruments used within each test were identical, this work furnishes rigorous data and objective information on both electric and gas IR technologies.
