Lowering Exhaust Gas Losses and Emissions with Newly Developed Recuperative and Regenerative Burners

摘要

The reduction of waste gas losses is often the most effective and economic way to increase the efficiency of industrial furnaces. The report will present new burner models, enabling to cut waste gas losses of finned recuperative burners almost in half. The regenerative burner achieves highest efficiency but one has accept a certain expenditure for cyclic switching and exhaust gas suction. This might not be justified for smaller burner sizes and furnaces. The new gap flow recuperative burner reaches almost the same efficiencies with a recuperative system. To increase the working temperature range, the gap flow heat exchanger can be combined with a ceramic heat exchanger. The new burner models use flameless oxidation technology for lowest NO_x emissions.
