The following table shows the Soviet classification of southern T.ESR coals
by content of volatile matter and coke-button characteristics. The PZh,
K and PS groups were considered "suitable" coking coals, but the other
groups were sometimes used in blending.

In the pre-World War II coking industry the percentage of gas coals in coal
blends in certain coking plants reached 15%. The use of gas coals in a

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:

(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.

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.

The Soviets' principal interest was in the low-temperature carbonization
of some types of low-grade coals such as the type "D", long-flame coals
of Lisichansk in the Donbas, the brown coals of the Moscow region, etc.
They planned to establish combination power stations and chemical recovery
plants. Further information on this and other questions is available at
the Library of Congress.
