Installation of a stoker-coal preparation plant in Krakow, Poland. Technical progress report 11, October--December 1996

This project is one of eight projects selected under the assessment program in the Support of Eastern Democracy (SEED) Act of 0989 by the federal government to reduce low-level emission sources in the Krakow area of Poland. The objective of this Cooperative Agreement is to demonstrate that the quality of stack gas emissions can be improved through the substitution of run-of-mine coal by washed coal. To this end, EFH Coal Company will design, build, and operate a 300-mtph (330 stph) preparation plant and produce a low ash, double-screened washed coal for burning in a traveling-grate stoker in one of the many water heating plants in the city of Krakow. By burning this prepared coal under proper combustion condition, combustion efficiency will be increased, stoker maintenance will be lowered and the amount of carbon monoxide, sulfur dioxide and particulates in the stack gases will be reduced significantly. Contracts to: provide the raw-coal feed to the plant; dispose of plant wastes; burn the clean coal in a demonstration water heating plant in Krakow; and to market any surplus production are in place. An international irrevocable purchase order has been let for the procurement of a customized modular 300 mtph (330 stph) dense medium cyclone preparation plant to wash the 20 mm ({approx} 3/4 in.) by 5 mm. ({approx} 1/4 in.) size fraction of raw coal produced by the Katowice Coal Holding Company. This plant will be fabricated and shipped from the United States to Poland as soon as the final land-us and construction permits are granted
