Energy conservation and pollution control (Abstract)

The paper discusses the effects of pollution control, particularly NO control, methods, on heat demands for the process. The effects of combustion modification methods, such as stoichiometric combustion, flue gas recirculation and steam or water injection are studied in a laboratory furnace and the results are analyzed to evaluate the least energy demanding method of N0X control. In addition to this, the effects of energy conservation methods, such as the reduction of excess air, use of preheated air and the oxygen enrichment of combustion air, on the N0X formation and emissions are discussed. The discussions are based on past experimental results.
