摘要

Coals of Upper Silesia are geologically young, having a volatile matter content well above 30% and a correspondingly high oxygen content, Narrower coke ovens and a shorter coking time were tried first. Then compression of the coal charge by means of stamp¬ing machines was tried and became almost universal in Silesian coke plants. While blending with coals of lower volatile content produces satisfactory metallurgical coke, Silesia's geographical location prohibits any extended use of low volatile coals because of their high delivered cost. When semi-coke obtained by low temperature carbonization is blended with Silesian coal and the charge stamped, a very satisfactory metallurgical coke is obtained. It is essential that care is taken in the preparation of the semi-coke to obtain a product which will blend satisfactorily with the coal used. Dr. Thau recommends the continuously operated vertical chamber oven for low temperature carbonization.
