Possibilities of production of smokeless fuel via carbonization of Czech coals
- Inst. of Rock Structure and Mechanics, Prague (Czechoslovakia)
It was consumed 48 -51 % of hard coal (total output 28 - 30 Mt/year) in a long period for the production of coke. It appears to be anomaly in comparison with other coke producers in Europe and in the world, it was predeterminated by {open_quotes}steel conception{close_quotes} of state`s economics. The production of coke reached 10-11 Mt/year in former Czechoslovakia in the period 1970-1990. A considerable quantity 1.2 - 1.7 Mt/year of produced coke was utilized for heating. In comparison, 7-5.4 Mt coke/year was it in Poland for the heating. Al coke production is realized on the basis of Czech hard coals mined in the southern part of Upper Silesian Coal District. The coke production is operated in multi-chamber system with full recovery of chemical products (gas, raw tar, raw benzene, amonium etc.). The future trend of smokeless fuel production in Czech Republic makes for to the non-recovery coke oven, it means to two-product processes (coke + reduction gas, coke + electricity and so on). Jewell--Thompson coke oven (hard coal) and Salem oven (ignites) represent nonrecovery nowadays. The possibility of it`s application in Czech Republic are discussed. Jumbo coking reactor system (European project No. 500 to the Eureka programme) produces primarily metallurgical coke. The strong Clean Air Act suspends the production of smokeless fuel in multi-chamber system also in Czech Republic for the future period 2010-2020.
