Discussed the selecting principle of pinch point and approach temperature point it is belong to the HRSG(heat recovery steam generator) of minitype combined gas-steam cycle.
论述了小型燃气—蒸汽联合循环中余热锅炉节点温差和接近点温差的选取原则。
By the use of the pinch point technique the all LTS heat exchange network is optimized in design, and the new network process obtained does not need external supply of steam.

FORBES: Mapping The World's Energy On The Move
This lobby's most powerful point is that the pinch on giving seems to contradict the government's own policies, not least David Cameron's vision of a Big Society, in which voluntary outfits play a bigger role in providing public services.
ECONOMIST: Why the dispute over tax and charity is so politically toxic

a traffic-calming measure in which the road narrows to one lane, with a sign indicating which oncoming driver should give way

夹点
According to the pinch theory, if cooling utility is used up the pinch point,heating utility is used down the pinch point or the heat exchange streams across the pinch,there will be double loss in the utility.
根据夹点理论，在夹点上方引入冷却公用工程、在夹点下方引入加热公用工程以及存在穿越夹点的换热流股，都会造成系统的加热和冷却公用工程的双重损失。
