Balancing Pulverized Coal Flows in Parallel Piping

Autor: A. A. Vetter, R. S. Vetter

Publikováno v: Journal of Engineering for Gas Turbines and Power. 107:679-684

The distributions of the two-phase (pulverized coal in air) fuel inputs through the 24 parallel coal transport pipes of a coal-fired power plant are determined with a computer code. The orificing which would provide balanced fuel inputs through these

Publikováno v: Tetrahedron Letters. 30:2901-2902

The sex pheromone of females of the carob moth, Ectomyelois ceratoniae, was identified to be a mixture of (Z,E)-9,11,13-tetradecatrienal, (Z,E)-9,11-tetradecadienal and (Z)-9-tetradecenal in the ratio of 10:1:1. A synthetic blend proved to be attract
