Industrial Pulse Combustor Development and Its Application in Spray Dryers and Cement Calciners. Final Report, May 1986-September 1990

摘要

Proof of concept (POC) and prototype tunable pulse combustor development for applications in industrial process heating is reported. A significant accomplishment of the work is the proof of a scalable pulse combustor design. Pulse combustors ranging from 0.5 MBtu/hr to 9.5 MBtu/hr were built and operated. Tests demonstrating the capability of these combustors to excite large amplitude resonant acoustic pulsations inside industrial-scale process enclosures are documented and operating parameters are quantified. The beneficial effects of conducting thermal processes in the presence of pulsations, in terms of fuel savings and/or increased productivity, are measured in a series of tests in which water spray is evaporated, kaolin slurry is spray dried and limestone is calcined at an operating cement plant.
