【摘要】：能源是社會發(fā)展的重要物質(zhì)基礎(chǔ)，節(jié)能是我國的一項基本國策，我國提出了建設(shè)節(jié)約型社會方針戰(zhàn)略，，在現(xiàn)有的技術(shù)條件下，提高火電機組的經(jīng)濟性就得靠合理的管理方法。 本文參考目前國內(nèi)外先進理論和技術(shù)的基礎(chǔ)上，針對神華國華滄東電廠一期2×600MW亞臨界機組的實際情況，分析了機組經(jīng)濟運行的現(xiàn)狀以及影響機組經(jīng)濟運行的影響因素，并且針對機組現(xiàn)有的運行方式，提出了提高機組經(jīng)濟運行的優(yōu)化措施，比如更改鍋爐的運行參數(shù)，改變汽輪機的進汽方式等。在一期機組的投產(chǎn)運行后，滄東電廠有一套機組運行指標(biāo)考核方法，對機組的運行經(jīng)濟性的提高起到很大的作用。但是，原有的管理方法有一定的局限性，本文分析了滄東電廠一期兩臺機組原有的指標(biāo)競賽管理方法，針對原方法的不利之處，提出了改進方法，也就是使指標(biāo)靠近額定參數(shù)的競賽管理方法，并做出了經(jīng)濟性評價。 同時電廠的煤場有很大的節(jié)能空間，筆者結(jié)合煤場儲煤的優(yōu)化建議，總結(jié)出了滄東電廠經(jīng)濟運行管理方案，為機組的經(jīng)濟運行提供指導(dǎo)，為機組的節(jié)能降耗和經(jīng)濟運行管理提供理論基礎(chǔ)。
[Abstract]:Energy is the important material foundation of social development, and energy saving is a basic national policy of our country. Our country has put forward the strategy of constructing economical society. Under the existing technical conditions, it is necessary to improve the economy of thermal power units by reasonable management methods. Based on the advanced theory and technology at home and abroad and the actual situation of the 2 脳 600MW subcritical unit in Huacangdong Power Plant of Shenhua, this paper analyzes the present situation of the unit's economic operation and the influencing factors affecting the unit's economic operation. In view of the existing operation mode of the unit, the optimization measures to improve the economic operation of the unit are put forward, such as changing the operating parameters of the boiler and changing the steam inlet mode of the steam turbine, etc. After the unit is put into operation in the first stage, Cangdong Power Plant has a set of evaluation method of unit operation index, which plays a great role in improving the operation economy of the unit. However, the original management method has some limitations. This paper analyzes the original index competition management method of two units in Cangdong Power Plant, and puts forward the improvement method in view of the disadvantages of the original method. That is to make the index close to the rated parameters of the competition management method, and made economic evaluation. At the same time, the coal yard of the power plant has great energy saving space. The author sums up the economic operation management scheme of Cangdong Power Plant combined with the suggestions of coal storage optimization in the coal yard, which provides guidance for the economic operation of the unit. It provides a theoretical basis for energy saving and consumption reduction and economic operation management of the unit.
