Modeling of integrated environmental control systems for coal-fired power plants: Conventional froth flotation for the IEC coal cleaning plant model. Quarterly progress report, [October 1, 1988--December 31, 1988]
This report describes the addition of a conventional froth flotation circuit into the FORTRAN coal cleaning module of the Integrated Environmental Control (IEC) model. The purpose of this modification is to include froth flotation as an option to clean the coal fines. The current model has three beneficiation: levels (2, 3, and 4) in which different streams are washed by specific gravity equipment. Level 2 washes only the coarse stream. Level 3 washes the coarse and medium streams. Level 4 washes the coarse, medium, and fine streams. This modification adds a fifth level, which uses specific gravity equipment to wash the coarse and medium streams and froth flotation equipment for the fine stream. The specific size fractions in each stream are specified by the model user. As before, the model optimizes the yield of each circuit in order to achieve a target coal quality for the cleaned coal product.
