FILTRATION OF THE COMBUSTION AIR AND THE COOLING AIR OF MOTIVE POWER UNITS. OPERATING TESTS WITH AIR FILTERS

This report deals with the operating tests on air filters carried out on behalf of the B 67 Specialist Committee. Their purpose was to ascertain whether, according to the quantity of dust retained, the filters used in service showed similar pressure drops to the filters tested in laboratory with the type of dust defined in Report No. 1 and using the concentrations selected for the tests described in Report No. 2. Results show severe scatter of the points measured, but with a few exceptions, the points measured were within the range of pressure-drop curves ascertained in the laboratory tests. The number of measurements was too small for any general quantitative validity to be given to them. Despite the limited number of tests made, it can be assumed that, qualitativley, the results of the laboratory tests are transferable to the practical field concerning the pressure drop.
