Abstract

The discharge coefficients in the air ports of the coal pick were measured by the calculation of the pneumatic frictional losses of these.<BR>Frictional coefficients are about 0.74 for both back and fore ports. Frictional coefficients are more than 0.4. If the pneumattic frictional loss is absent, an increase of a thermal efficiency will be lower than 5%, and an increase of effective power will be 18-20%. This fact is considered to be unnegligible.
