This stu(~y deals with the problem of improving' the efficiency of feed pump: drives I and!, the selection of pressure-for booster pumps..

The following conclusions were made: 1) Takln'g:into account~;the 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! 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 L'i. 10695 66 A 003?~2.

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.

This stu(~y deals with the problem of improving' the efficiency of feed pump: drives I and!, the selection of pressure-for booster pumps.. Both steam turbodriv -es, and,electrodtives were investigated. The tests were conducted with K-300-240, and K- 0 -246.turbines- 5 0 at 3000- 5000 rjam. The following conclusions were made: 1) Takln'g:into account~;the 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! 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 L'i. 10695 66 A 003?~2.

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.
