A 750 hr. test of an Allis-Chalmers gas turbine fitted with a multi-tube fly-ash separator to minimize turbine blade erosion at power levels above 3000 hp. was undertaken. It is evident from this test that there must be complete removal of all fly-ash particles larger than 20 microns, or roughly 0.001 in. dia. The two coal pumps stood up well to their work, and showed relatively little abrasion after 575 hr. continuous service; control of the rate of feed also was satisfactory. Ring-supported combustors came through the test in good conditions after 140 hr. of oil-burning and 698 hr. of coal-burning, showing a combustion efficiency consistently about 95 percent.
