All zirconia combustion chamber for testing fuels prevents "flashback" accidental extension of flame into fuel supply line. Chamber consists of hemispherical injector on base surrounded by hemispherical cap. Cap has two additional ports for thermocouple and gas sampling probes.
Simple and inexpensive method of making quartz injectors yields injectors of superior characteristics. Quartz injector is fabricated by heating quartz rod and blowing and forming sphere on end. As with metal injectors, orifices are then drilled in spherical shell. Time required to form quartz is only 0.5 man-hour and 7.5 man-hours are required to drill holes. Total time of fabrication, 8 man-hours, is fraction of 40 man-hours required to complete metal injector. Success with technique and material is such that further substitutions for other related components are being contemplated.
