Pulse Combustion Engineering Research Laboratory: Combustion Chamber. AnnualReport, July 1, 1990-June 30, 1991

摘要

A pulse combustion research laboratory for low pressure systems was put intooperation to investigate and resolve, on a fundamental level, issues affecting practical applications of pulse combustion technology. In the second year of the program, a NOx data base was completed with a collection of steady-state emissions data for 13 sizes and configurations of hot water boilers covering input rates from less than 100 to over 1,000 MBtu/hr. The effects of flue-gas recirculation on emissions and the overall performance were studied. Effects of air/gas mixing on combustor performance and the effects of changing gas supply pressures were investigated. To determine the effects of radiative heat loss, both ceramic and wire-mesh bodies were inserted into the combustion chamber. A linear acoustic model was developed under a sub-contract and showed that linear acoustics are capable of representing a considerable part of the underlying physics of pulse combustion. A computerized bibliographic data base on pulse combustion information is being built up.
