【摘要】：節(jié)約能源,是指加強(qiáng)用能管理,采取技術(shù)上可行、經(jīng)濟(jì)上合理以及環(huán)境和社會(huì)可以承受的措施,從能源生產(chǎn)到消費(fèi)的各個(gè)環(huán)節(jié),節(jié)能降耗、較少損失和污染物排放、制止浪費(fèi),有效、合理的利用能源。 火電廠是一次能源用能大戶,全年耗煤量非常巨大,提高火電廠的一次能源利用率,盡可能的降低發(fā)電成本,成為全國(guó)各大發(fā)電企業(yè)及科研院所研究的課題。隨著經(jīng)濟(jì)規(guī)模進(jìn)一步擴(kuò)大,能源需求還會(huì)持續(xù)較快增加,能源將是我國(guó)當(dāng)前和今后相當(dāng)長(zhǎng)一個(gè)時(shí)期內(nèi)制約經(jīng)濟(jì)社會(huì)發(fā)展的突出瓶頸。本文從提高火電廠高壓加熱器經(jīng)濟(jì)性能出發(fā),通過(guò)對(duì)我廠600MW燃煤汽輪發(fā)電機(jī)組高壓加熱器性能的試驗(yàn)研究及技術(shù)改造,分析了影響高壓加熱器性能的主要因素及常見(jiàn)的故障現(xiàn)象,采用灰色關(guān)聯(lián)分析法實(shí)現(xiàn)了高壓加熱器的故障診斷,保證高壓加熱器的經(jīng)濟(jì)、安全運(yùn)行,實(shí)現(xiàn)火電機(jī)組的節(jié)能降耗。
[Abstract]:Energy conservation refers to strengthening energy use management, taking measures that are technically feasible, economically reasonable and affordable to the environment and society, from energy production to consumption, energy conservation and consumption reduction, less loss and pollutant emissions, and stopping waste, Efficient and rational use of energy. Thermal power plants are large users of primary energy, and the annual coal consumption is very large. To improve the primary energy utilization ratio of thermal power plants, and to reduce the power generation costs as much as possible, It has become a research topic for major power generation enterprises and scientific research institutes throughout the country. With the further expansion of the economic scale, the energy demand will continue to increase rapidly. Energy will be a prominent bottleneck restricting economic and social development in China at present and for a long time to come. This paper starts from improving the economic performance of high-pressure heaters in thermal power plants. Based on the experimental study and technical renovation of the high pressure heater performance of 600MW coal-fired turbogenerator set in our factory, the main factors affecting the performance of the high pressure heater and the common fault phenomena are analyzed. The fault diagnosis of high pressure heater is realized by grey correlation analysis method, which ensures the economical and safe operation of high pressure heater, and realizes the energy saving and consumption reduction of thermal power unit.
