:PURPOSE.: This book Is Intended for industriallengineering students",
specializing in turbo-blower operation.and for independent'study~~-
of turbo-blower servicing problems.
COVERAGE: 'The book presents basic problems in the operation.of turbo-
blowers-and auxiliary equipment and discusses measures for pre7,~
venting abnormalities during operation. In order.to explain the,
operating principles of steam-turbines, air-blo,wers,and auxiliary
equipment, basic information on physics mechanics and engineer-.''.

This stu(~y deals with the problem of improving' the efficiency of feed pump: drives I and!,

siglificant pressure. losses in the steam supply lines leadingto and from the ttirbo-
erature drop of the working steam used in the t
drive of the feed pump, the temp urbo
drive is lower than in the corre 24o!

and 20% in K-300-24o). 2),In turbines,with supercriticalsteam pressures, I is
necessary to use hi0i,-rpm. feed pumps with a preconnected booster pump. 3) Since.

PERIODICAL: Teploenergetilca, 10,58, No.4, p -.93. (USSR).
ABSTRACT: In many power stations.i.t is necessary, for various.
reasons, to throttle,and cool live steam This is, of
course 7 wasteful and every attempt shoula be made to
increase the efficiency of reducing and c.ooling,installations.
One method is to cool the steam by.feed-water from the.'.~ I
high-pressure heaters ~nstead.of using feed-wate,r at a
temperature of 102-104 C.from the feed ptimps. Calculations
are Given which show the considerable economy that can
result from this measure. In aparticularcase the
consumption of live steam was reduced by 1%, and in-ano,ther
case by 4yo.
There is 1 table.

This stu(~y deals with the problem of improving' the efficiency of feed pump: drives I and!,

erature drop of the working steam used in the t
drive of the feed pump, the temp urbo
drive is lower than in the corre 24o!
spon'ding stages of the main turbine (7%:in,the,K-500-
and 20% in K-300-24o). 2),In turbines,with supercriticalsteam pressures, I is
necessary to use hi0i,-rpm. feed pumps with a preconnected booster pump. 3) Since.
booster -pumps have no reduction gears and the hydraulic couplings.and-thus no:losses I

PERIODICAL: Teploenergetilca, 10,58, No.4, p -.93. (USSR).
ABSTRACT: In many power stations.i.t is necessary, for various.
reasons, to throttle,and cool live steam This is, of
course 7 wasteful and every attempt shoula be made to
increase the efficiency of reducing and c.ooling,installations.
One method is to cool the steam by.feed-water from the.'.~ I
high-pressure heaters ~nstead.of using feed-wate,r at a
temperature of 102-104 C.from the feed ptimps. Calculations
are Given which show the considerable economy that can
result from this measure. In aparticularcase the
consumption of live steam was reduced by 1%, and in-ano,ther
case by 4yo.
There is 1 table.
