A method and apparatus for modeling flow in a bunker detects material characteristics of material supplied to a bunker and predicts the type of flow from the sensed material characteristics. Material characteristics of the material subsequently discharged from the bunker are compared with the material characteristics of the material supplied to the bunker to verify the prediction of flow in the bunker. The method and apparatus can be applied to bunkers storing coal at a power plant where moisture content, heating value, sulphur, etc. are detected by a bulk material analyzer prior to being supplied to a plurality of bunkers. Even if the coal is subsequently mixed prior to combustion, estimates can be made of the contribution of each bunker to the resulting heating value, moisture removed, sulphur, ash content, etc. An appropriate flow model predicting one of mass flow, rat hole flow and funnel flow can be selected based upon characteristics of the material supplied to and discharged from the bunkers.
