Special consumers of sea`mal hydroelectric paver have become of practical
importance for regions with large hydroelectric power resources and a fuel balance
problem. This is partioalarly true during the first stages of developmnt of
vast hydroelectric power resources before finished rayon and inter-rayon power
systems have been put into' operation. These regions include the Tadzhik.. SSR, the
Kirgiz 88R, Eastern Sizalb SERI, the northern Caucasus, Transcaucasia, and the north-
western regions of the BUR, among others.
Previously, on the basis of the study and generalization of prolonged expsri-
sents in the operation of carbide and ferroalloy furmoes, the author worked out
power engineering and economic characteristics which determine the conditions for
efficient use of these industries as consumers of electric paver, using the seasonal
schedule of a hydroelectric station.
The cost structure of calcium carbide and ferrosilicon produced with power
from a hydroelectric station operating on unregulated flow consists of the follow-
ing factors:
1. Materials sake up 25-30 percent of the cos,. of calcium carbide and 30-40
percent of the cost of ferrosilicon. The cost of materials it practically constant
in passing over to the seasonal power schedule.
2. The wages of production. workers constitute only a small percentage of the
cost of calcium carbide and ferrosilcon. Thus, even substantial changes in the
wages of production workers, while passing over to seasonal operation, cannot great-
ly influence the economics of the production of calcium carbide and ferrosilicon.

3. The electric power component has a decisive influencR upon the cast of
production. When using electric power from steam-electric stations, the power
component accounts for 40-45 percent of the production cost, while with hydro-
electric power it comprises about 20-25 percent of the cost.
of production, comprising about 30-40 percent of the latter.
This limits possibilities of lowering production costs to the seasonal power
schedule. Generalization of prolonged operational experience resulted in the
establishment of new powoi?-economic relationships in the operation of carbide
and ferroalloy furnaces on the seasonal schedule of hydroelectric stations.
schedule (for a given installation and operating conditions) varies within the
compare.tively small limits of 3-7 percent and reaches 10 percent only in rare
The proper selection of furnace capacity is of great importance. Installa-
tion of heavy-duty furnaces when operating on the seasonal power schedules re-
duues the coefficient of utilization of the hydroelectric station; the Installs-
rate which, in turn, causes an increase in the unit capital investment per pro-
duction ton.
Analysis of the factors invol-ed /data given in tables and graphs in origins'
shows that the unit capital investment per rated kilowatt is reduced with an in-
crease in power of the electrical installation. On the other hand, the efficiency
per rated kilowatt for stations operating on an unregulated water flow decreases
with an increase in power because the greater the discharge utilized, the shorter
its duration. In accordance with this, the economic indices of both the hydro-
electric station and the factory are greatly affected. Furthermore, as the in-
dex for water-flow utilization changes, the engineering-economic Indices for the
hydroelectric station and the factory diverge sharply. All this confirms the con-
clusion that the problem of utilizing seasonal hydroelectric paver can be properly
judged only after working out the engineering-economic indices for a given water
flow in the combined hydro station-electric furnace aggregate. Analysis of the
power-econommic indices on the basis of the hydroelectric system alone invariably
leads to one-sided and incorrect conclusions.
Another aspect of the problem was to compare the basic economic indices of
a hydro station with that of a steam station, taking into eccouat the latter's
fuel base. It was found that a hydro station would pay for its capitalization
much sooner than would a steam station. In addition, studies showed that labor
productivity for the factory-hydro aggregate and factory-steam aggregate was
aboi.c the same when the seasonal operation as 5U percent of noral operation.
Conclusions
Allocation of electric furnaces to areas having hydroelectric power re-
sources available on a seasonal basis will make possible more efficient utiliza-
tion of the water-power resources by increasing the coefficient of flow utiliza-
tion,
Electric furnaces can be operated advantageously on the seasonal power
schedule from the viewpoint of paver engineering, technology, and economics.
In this capacity, the furnaces become profitable consumer regulators.
