一种热电联产机组及其运行效率的评价方法
摘要：
本发明涉及一种热电联产机组及其运行效率的评价方法，主要分为以下步骤，第一步，计算热电联产机组的循环吸热量和对外供汽的热量；第二步，计算热电联产机组的发电比率和供汽比率；第三步，计算单位标准煤燃烧所能产生的对外供电的电能及对外供汽的热能；第四步，计算燃烧单位标准煤的最终净收益；第五步，比较不同热电联产机组燃烧单位标准煤的最终收益，收益大的热电联产机组运行效率高。它的最终计算结果是以往衡量热电联产机组运行效率的多种指标的一个综合体现，它更加直观，无论专业人员还是非专业人员都非常容易理解。
摘要（英）：

The invention relates to a cogeneration unit and an operation efficiency evaluation method thereof. The operation efficiency evaluation method mainly comprises following steps: the first step of calculating circulation heat absorption capacity and external steam supply heat of the cogeneration unit; the second step of calculating power generation ratio and steam supply ratio of the cogeneration unit; the third step of calculating external power supply electric energy and external steam supply heat energy generated by combusting one unit of standard coal; the fourth step of calculating final net earning of combusting the unit of standard coal; and the fifth step of comparing final earnings of the unit of standard coal combusted by different cogeneration units. The cogeneration unit with large earning is high in operation efficiency. The final calculating results can be comprehensive embodiment of various indexes for measuring operation efficiency of the cogeneration unit. The operation efficiency evaluation method is visual and easy to understand for professional staff and non-professional staff.
