This report describes the progress made during the second Quarter of a two year project to demonstrate that the air pollution, from a traveling grate stoker being used to heat water at a central heating plant in Krakow Poland, can be reduced significantly by replacing the unwashed, unsized coal now being used with a mechanically cleaned, double sized stoker fuel and by optimizing the operating parameters of the stoker. It is anticipated that these improvements will prove to be cost effective and hence be adopted in the other central heating plants in Krakow and indeed throughout Eastern European cities where coal is the primary source of heating fuel. EFH Coal Company has formed a partnership with two Polish institutions -- MPEC a central heating company in Krakow and Naftokrak-Naftobudowa, preparation plant designers and fabricators for this effort. The washability data from a 20mm x 0.5mm size fraction of raw coal from the Staszic Mine were evaluated. The data show that the ash content of this coal can be reduced from 24.4 percent to 6.24 percent by washing in a heavy media cyclone at 1.825 sp.gr.; the actual yield of clean coal would be 76.1 percent. The quest for long-term sources of raw coal to feed the proposed 300 tph stoker coal preparation plant continued throughout the reporting period. Meetings were held with Polish coal preparation equipment suppliers to obtain price and delivery quotations for long lead-time process equipment. Preliminary cost evaluations were the topic of several meetings with financial institutions regarding the cost of producing a quality stoker coal in Poland and for identifying sources of private capital to help cost share the project. The search for markets for surplus production from the new plant continued.
