1、大兴热电厂三种蒸汽定价方案的比较Comparison of 3 Fixing Price Proposal of Steam From Da Xing Thermal Power Plant 2010年 12月 20 日，NNJ化工园区管委会、 S （中国）投资有限公司、吉林分公司及白山电厂三方代表在NNJ化工园管委会第七会议室就S 公司在 NNJ化工园大兴片区拟建醋酸、乙醇项目的蒸汽供应问题进行了沟通和交流。其一期项目2011年三季度开工建设，预计 2013 年四季度建成投产，蒸汽需求平均流量140150 t/h ， ；二期项目预计 2015 年建成投产，蒸汽需求平均流量140150 t/h
2、 ；两期建成后蒸汽需求为：一般流量 290 t/h ，最大流量 366 t/h 。就会上提出的三种蒸汽定价方案，请吉林省电力设计院相关专业人员进行了测算，比较分析如下：Dec.20th 2010, NNJ Chemical Industry Park Management Committee /Jilin branch of S(China)Investment Co . , Ltd / Baishan power plant , the representatives of the above three sides have a meeting of communicating and d

10、处于合理的水平。On the current stage, the unit static investment of small thermal power unites is about 9000yuan/kW, the unit static investment of the project is 18215yuan/kW, it appears to be quite high, the main reason is that the regular situation is making use of the 50MW generator to match the 220t/h b
11、oiler, but two sets of CB20 back pressure units is made use in our project. If we make use of the 50MW generator, the unit investment will be less than 9000元/KW ，so that, the investment of the project is reasonable. 二、 三种方案的比较the Comparison among the 3 Proposals 1、经济评价原始数据表（见表2）Original Data Table o

32、NJ化工园、S、HN三方会谈中，12% 内部收益率是化工园方面提出的一个参考值，尚未得到S及 HN方面的确认，对此我方需进一步核算，确定我方谈判方向。Internal income value :12% is a reference value raised by chemical industry park during the meeting of Dec. 20th 2010 among NNJ chemical industry park, S,and HN . The reference value has not confirmed by both S and HN , for w
33、hich we will further check ,so as to confirm our discussion direction. （2）公式中投资额的数值。在表3 中取用的投资额值是电厂全部投资，塞拉尼斯能否接受该值是打问号的！预计塞拉尼斯会提出投资额值为电厂满足其用汽能力部分的投资（举例说电厂全部供热能力为400t/h ，塞拉尼斯需要电厂300 t/h 保障供应，则塞拉尼斯承担总投资额的75% ） ，该由塞拉尼斯承担总投资额的比例是我方在谈判中的主要关注之一；影响投资额的另一因素为塞拉尼斯对于可靠性要求的高低， 目前的投资额是电力设计院按照常规供热电厂进行系统设计配置，若塞拉尼斯
34、对供热可靠性有更高要求，则投资额会进一步增加， 这也是与塞拉尼斯谈判时需说明的。The data of investment value of Formula 1 .The data used in Table 3 is the total investment of the power plant. It is still a question whether Celanese could approve the data. It is estimated that Celanese would accept the part of investment value which is use
35、d to meets their steam requirements (e.g. the total heating capability of the whole power plant is 400t/h, the requirements from Celanese is to fulfill 300 t/h , the Celanese 名师资料总结 - - -精品资料欢迎下载 - - - - - - - - - - - - - - - - - - 名师精心整理 - - - - - - - 第 10 页，共 19 页 - - - - - - - - - would afford 75
36、% of the total investment.) （3）年供热量大小。本项目因是建设背压机组，发电量大小完全取决于供热量的大小。 供热量一方面是影响供热的收益，另一方面是影响发电收益， 因此供热量大小对电厂的效益影响非常大。公式中年供热量作为分母， 其数值大则相应热价可降低。表3 中，供热量为 162 万吨/a 、上网电量 14000万 KWh/a ，而按塞拉尼斯一期 140t/h 、年需求约 98 万吨/a（年运行小时 7000h/a） ，二期投产后约 200 万吨/a ，因此在商谈塞拉尼斯年蒸汽需求量时，要求塞拉尼斯 “照付不议”的年蒸汽量为 170 万吨/a ，力争签订 200 万
37、吨/a ，则可保证投资收益在较好水平。The heating capacity per annum. The generating capacity completely depends on the heating capacity due to the project is making use of the backpressure unites. The heating capacity impacts the heating income on one hand, and generating income on the other hand. So the heating capa
38、city makes quite a big influence for the total benefit. The data of heating capacity is as denominator in formula 1 ,so if the date is largen ,the relevant heating price will be lower. In the table 3 , the heating capacity is 1.63million ton/a, electric quantity on line is 140 million ton/a . Howeve
39、r, according to Celanese s first term 140t/h and 980 thousand ton/a of annual requirement(annual working hours 7000h/a), after second term startup about 2million ton/a, so when the negotiation of the steam requirements of Celanese starts, we should require Celanese make the annual steam quantity to
