Advancement of developmental technology for pulse combustion applications

The major results in the areas of stand alone pulse units mixing and decoupling are presented. A self-starting pulse unit is designed and successfully tested up to an imput rate of 100,000 Btu/hr. A setup to generate power from puse unit exhaust gases is also put together. In the area of decoupling, major factors affecting design of inlet and exhaust decouplers are identified. Changes in these factors affected burner stability, operating frequency and the phase relationship between burner and decoupler pressures. Frequency scan analysis is used to simulate frequency response of several burner/decoupler combinations. In the area of mixing, a multiple pipe pulse unit is fabricated and used to obtain baseline data on mixer head performance.
