A pulse combustion research laboratory for low pressure systems has been put into operation to investigate and resolve, on a fundamental level, issues affecting practical applications of pulse combustion technology. The program of experimental research undertaken during the first year of the program was to develop a body of information on the NOx emissions from 12 vertical hot-water boilers with different configurations and nominal input rates from 150,000 to 750,000 Btu/hr. During steady-state operation with inlet water at 120 deg and outlet at 140 deg F, NOx levels were between 25 and 50 ppm (3% O2 basis) over a range of input rates from 90,000 to 1,000,000 Btu/hr and equivalence ratios from 0.66 to 0.92. This investigation is 50% completed. In a concurrent effort, an acoustic model is being developed to provide a framework within which empirical knowledge of pulse combustion can be understood. It focuses on the feedback mechanism responsible for pulsations and its relation to the detailed geometry of the entire pulse combustion system. In addition, a computerized bibliographic data base with which to access a file of documents on pulse combustion is being established.
