The PZh, K and PS groups were considered "suitable" coking coals, but the other groups were sometimes used in blending.

CONFID TIAL -2- coal blend made it easy to push the coke cake from the oven, reduced the cross-fissuring of the coke and increased the yield of coal chemicals and coke-oven gas. Ian article in post-World War II USSR coke literature described the use of up to 25% gas coals in the Stalino coking plant in the Donetz Basin. According to the article, this resulted in a good quality blast furnace coke, easier conditions for coke oven operation, and reduction of coking time from 16.4 hours to 15.9 hours. The use of more gas coal results in a decreased yield of coke and an additional load on the recovery plant because of the increased yield of by-products. Changes were necessary in the operating conditions of the coke ovens and the chemical recovery plants. (See 2 above) The use of class "T" coals instead of "K" and "PS" coals as a leaning component of coal 'blends is very desirable, but requires special equipment for fine disintegration of "T" coals. Nevertheless, "T" coal has been used In some USSR coking plants. One example is the Staro-Makeevskiy plant which in 1934 used 8.3% "T" coals. In the first six months of 1939 the average consumption of dry coal for one ton of dry coke was as follows: (a) In the southern coking industry - 1.418. (b) At the Kemenc;To coking plant - 1.269. The average percentage of breeze in the coke produced in 1939 was as follows: (a) The Donbas plants - 6.03% (b) One of the Ural plants - 11.7% (c) One of the Kuzbas plants - 10.64% The following were the principal difficulties in the coke industry in 1939: Approved For Release 2003/09/03 : CIA-RDP82-00047R000400110005-9 Approved For Release 2003/09/03 : CIA-RDP82-00047R000400110005-9 25X1 CONi'IJ IWIIAL -3- (a) (b) Coal cleaning. Requirements for both quantity and quality could not be met by the coal cleaning plants. (c) Coke production. The coke ovens could not meet the requirements of the blast furnaces in either quality or quantity. In 1938 production was only 87% of the planned amount, and in the first half of 1939 was 96.4%. Also the average ash content of the coke was 10.74% in the first half of 1939 when the plan called for a maximum of 10%. (d) misuse of coke oven gas. The metallurgical furnaces frequently lacked fuel gas because the coke oven gas was either wasted or used 25X1 for underfiring the coke ovens. 25X1 The percentage of by-product coke to total coke produced in the is shown in the following table. 79.3 25X1 25X1 84.1 1931_ 1 2 1934:* 193 86.3 90.1 ?2-0- 89.7- 91.0- *Ruropean part of USSR only. ,There follow the names of some non-recovery coking plants located in the Donbas, viz: Coal supply. In 1938 coal deliveries to the coke industry were only 88.3% of the planned objective, and in the first six months of 1939 Only 93-6%. In addition, 7.5% to 9.27% of the coal delivered vex defective or unconditioned.
