關鍵詞:閥門內漏;實時監測;節能;績效考核中圖分類號:TK262文獻標識碼:A文章編號:1673-1131(2013)09-0093-02 0前言 隨著電力體制改革,面對國家日益嚴格的節能減排要求,火力發電企業越來越關注發電機組的節能減耗和發電成本的降低。而減少機組閥門泄漏量是其中一個重要的節能減耗手段。 泄漏是火力發電廠中常見的故障之一,尤其是鍋爐的四管泄漏問題是火電廠停機的主要故障。目前,大多數發電企業對閥門泄漏定期檢測,不僅浪費了大量人力和物力,而且檢漏不及時,長期泄漏導致的爆管引發設備及人員安全隱患。 閥門泄漏常用檢測方法有基于超聲、氦質譜等檢漏法,這些檢測方法都具有一定的局限性,而基于溫度等運行參數的外部檢漏法,具有非接觸、在線、實時測量等優勢。通過創建火電機組閥門綜合管理平臺,可以給電廠運行人員提供閥門檢修、檢漏的依據和參考,具有重要意義和廣泛的應用前景。 1閥門泄漏判斷依據 根據閥后溫度測點及系統相關溫度、閥門開關狀態、機組負荷等參數將閥門泄漏狀態劃分為正常、輕度泄漏、中度泄露和嚴重泄漏四種狀態。閥門泄漏狀態劃分具體步驟如下。 1.1前提判斷條件 我們系統設定的判斷條件一般為:機組負荷大于機組zui低斷油穩燃負荷,并且持續24小時。也就是機組正常運行24小時之后才會統計,這樣有效地過濾掉非正常運行的冗余數據,更真實地反應實際運行泄漏情況。6323D-611-PM-501DA9 ,6511B-222-PM-501DA9 ,PPC5A-ABB-AGAA,PPC5C-ABC-FGBA-CAA-AD ,PPC5C-ACB-AGAA-CAA-GB ,PRA1A-ECAA PRA1A-EDAA, 52A-11-AOB-GEMO-IKJ, 44B-ABA-GDFC-1KA ,45A-SC2-DDVD-1BA,
