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 coal transport pipes under nominal load conditions is also calculated with the code. Over the entire range of loading, the orificing determined with the code provides much smaller fuel imbalances than the imbalances which result with the previously installed orificings.
