摘　　要：为实现热能按质利用,采用引射汇流装置实现再热冷段与五段抽汽联合供汽,替代原有从再热热段减温减压后的对外供汽方式;采用等效热降法对某330MW热电联产机组进行了计算,结果表明,机组负荷在250MW以上时,采用引射汇流装置节能效果明显。To make use of thermal energy according to the quality,the injection afflux installment is adopted to realize the combined steam supply by the reheat cooling section steam with the steam of the fifth section extraction,which can replace the original heating mode that reheat steam after depressurization. Equivalent entropy drop method is used for a 330 MW cogeneration unit calculation. Results show that there is an obvious energy-saving enhancement for heat supply by using the injection afflux installment,when the unit load is above 250 MW.
