style="text-indent:25px">汽輪機(jī)根據(jù)熱力學(xué)原理，新蒸汽參數(shù)越高，熱力循環(huán)的熱效率也越高，早期汽輪機(jī)所用新蒸汽壓力和溫度都較低，熱效率低于20％。隨著單機(jī)功率的提高，30年代初新蒸汽壓力已提高到3～4兆帕，溫度為400～450℃。隨著高溫材料的不斷改進(jìn)，蒸汽溫度逐步提高到535℃，壓力也提高到6～12.5兆帕，個別的已達(dá)16兆帕，熱效率達(dá)30％以上。50年代初，已有采用新蒸汽溫度為600℃的汽輪機(jī)。以后又有新蒸汽溫度為650℃的汽輪機(jī)?，F(xiàn)代大型汽輪機(jī)通常采用新汽壓力24兆帕，新汽溫度和再熱溫度為535～565℃的超臨界參數(shù)，或新汽壓力為16.5兆帕、新汽溫度和再熱溫度為535℃的亞臨界參數(shù)。汽輪機(jī)的短葉片和中長葉片通常在葉頂用圍帶連在一起，構(gòu)成葉片組。廣東汽輪機(jī)生產(chǎn)</p><p
