焦化發(fā)電機(jī)組是整個(gè)電站的核心部件，價(jià)格很高，檢修成本也是最大的，因此對(duì)焦化發(fā)電機(jī)組的關(guān)鍵部件，如燃燒系統(tǒng)部件的火焰筒、過(guò)燒段，熱通道部件透平噴嘴、動(dòng)葉、靜葉、復(fù)環(huán)等檢查、維修、更換要制定科學(xué)合理的檢修計(jì)劃和檢修周期，延長(zhǎng)使用壽命，減少維修費(fèi)用，提高經(jīng)濟(jì)效益。

　　The coking generator unit is the core component of the entire power plant, with a high price and the highest maintenance cost. Therefore, a scientific and reasonable maintenance plan and cycle should be formulated for the inspection, maintenance, and replacement of key components of the coking generator unit, such as the flame tube and over burning section of the combustion system components, the turbine nozzle, moving blades, stationary blades, and complex rings of the hot channel components, in order to extend the service life, reduce maintenance costs, and improve economic efficiency.

　　檢修計(jì)劃和檢修周期的制定要綜合考慮燃料的特性、機(jī)組運(yùn)行方式、水或蒸汽注入、啟動(dòng)次數(shù)、環(huán)境因素、現(xiàn)場(chǎng)窺孔檢查結(jié)果、熱通道部件的可靠性分析、機(jī)組的狀態(tài)檢修等因素，結(jié)合歷次大修、小修的間隔、部件的修理和更換間隔來(lái)確定。

　　The development of maintenance plans and maintenance cycles should comprehensively consider factors such as fuel characteristics, unit operation mode, water or steam injection, startup frequency, environmental factors, on-site inspection results, reliability analysis of hot channel components, and unit maintenance status. It should be determined based on the intervals between major and minor repairs, as well as the repair and replacement intervals of components.

　　焦化發(fā)電機(jī)組主機(jī)的檢修按檢修的范圍分為小修（燃燒檢查）、中修（熱通道檢查）和大修。

　　The maintenance of the main engine of coking power generation units is divided into minor maintenance (combustion inspection), medium maintenance (hot channel inspection), and major maintenance according to the scope of maintenance.

　　焦化發(fā)電機(jī)組日常維護(hù)是確保機(jī)組安全、穩(wěn)定、經(jīng)濟(jì)運(yùn)行的基礎(chǔ)工作。包括機(jī)組在啟動(dòng)、運(yùn)行、停機(jī)過(guò)程的監(jiān)視檢查，停機(jī)后的檢查維護(hù)和定期試驗(yàn)工作。不同廠家、不同型號(hào)的焦化發(fā)電機(jī)組應(yīng)根據(jù)制造廠家的運(yùn)行維護(hù)指導(dǎo)手冊(cè)、環(huán)境因素、燃料的種類(lèi)、運(yùn)行方式、設(shè)備制造質(zhì)量、和相關(guān)配套輔機(jī)設(shè)備的行業(yè)規(guī)范等制定相應(yīng)的日常檢查項(xiàng)目和檢查工藝。

　　The daily maintenance of coking power generation units is the fundamental work to ensure the safe, stable, and economical operation of the units. This includes monitoring and inspection of the unit during start-up, operation, and shutdown processes, as well as post shutdown inspection, maintenance, and regular testing work. Different manufacturers and models of coking power generation units should develop corresponding daily inspection items and inspection processes based on the manufacturer's operation and maintenance manual, environmental factors, fuel types, operating modes, equipment manufacturing quality, and industry standards for related supporting auxiliary equipment.

　　焦化發(fā)電機(jī)組的維護(hù)主要是焦化發(fā)電機(jī)組的在線清洗和離線清洗。焦化發(fā)電機(jī)組的在線清洗和離線清洗，要根據(jù)運(yùn)行工況和日常檢查情況及每次清洗的效果制定合理的周期，確保機(jī)組運(yùn)行的經(jīng)濟(jì)性和安全性，同時(shí)建立完整的檢查維護(hù)記錄，包括清洗前后的狀態(tài)、清洗的周期，清洗效果，清洗后運(yùn)行情況等，為下次清洗維護(hù)和機(jī)組大修提供參考依據(jù)

　　The maintenance of coking power generation units mainly includes online and offline cleaning of coking power generation units. The online and offline cleaning of coking power generation units should be carried out according to the operating conditions, daily inspection results, and the effectiveness of each cleaning cycle, in order to ensure the economic and safety of the unit operation. At the same time, a complete inspection and maintenance record should be established, including the status before and after cleaning, cleaning cycle, cleaning effect, and operation after cleaning, providing reference for the next cleaning and maintenance and unit overhaul
