    華能平涼發電有限責任公司2×600MW機組

    2018-12-09文章來源:原創文章

    1、工程概況

      華能平涼電廠廠址位于甘肅省平涼市附近的二十里鋪,該廠共裝有4臺300MW和2臺600MW國產燃煤供熱機組(5#和6#),天和技術的等離子體點火系統應用在2臺600MW機組上。鍋爐由哈爾濱鍋爐廠有限責任公司生產的超臨界參數、單爐膛、一次再熱、前后墻對沖旋流燃燒方式、尾部雙煙道布置、噴水減溫控制過熱汽溫、尾部煙氣調節擋板調節再熱氣溫、容克式三分倉回轉式空氣預熱器、固態排渣、平衡通風、緊身封閉、全鋼構架、全懸吊結構的Π型直流爐。采用中速磨煤機冷一次風機正壓直吹式制粉系統,每臺爐配6臺中速磨煤機,5臺運行,1臺備用。每臺磨煤機帶1層燃燒器,每層布置有5臺旋流燃燒器。

      2、煤質特性

      設計和校核煤種的煤質成分分析見下表:

      3、等離子燃燒器改造方案

      將鍋爐前墻最下層5只旋流煤粉燃燒器改造為兼有等離子體點火功能的等離子燃燒器。該類型的燃燒器其一次風、二次風均為旋流。中心風管內裝有啟動油槍和高能點火器。

      拆除原燃燒器的中心風管及其內部的啟動油槍,置換為等離子燃燒器,不對原燃燒器的一次風管及噴口做任何改變。另外在前墻最下層每只燃燒器前的一次風煤粉管道上加裝分流閥,點火時分流閥將煤粉導入等離子燃燒器。原燃燒器中心風管道上增設一電動插板門,等離子點火時關閉,點火結束時打開,恢復原燃燒器中心風的功能,防止燃燒器噴口超溫。

      4、項目運行情況

      該項目等離子體點火系統2009年8月開始正式安裝,于2009年10月首臺鍋爐進行點火吹管。在鍋爐點火吹管、空冷島吹掃、168整體啟動過程中全程使用等離子體點火系統,成功實現了零投油。兩臺爐的等離子體點火發生器累計使用時間均超過300小時,總體運行穩定、點火效果好。

      據電廠介紹,與 1#~4#爐等離子體點火系統綜合比較,5#、6#爐的等離子體點火系統在以下幾個方面有著比較明顯的優勢:

      (1)燃燒情況穩定,從未出現結焦情況;

      (2)天和技術的等離子體發生器采用軸向插入燃燒器,方向與煤粉氣流方向一致,相對1#~4#爐的徑向(或斜向)插入,既減小了阻力,也減輕了磨損,更重要的是消除了等離子體弧和煤粉火焰對燃燒器筒壁造成燒損和結焦的可能。在燃燒過程中,燃燒器的壁溫始終保持在200度左右。

      (3)功率大、煤粉燃盡率高、適應煤種范圍廣;

      (4)在冷態點火啟動15分鐘后鍋爐煙囪的煙就開始呈灰白色。在點火吹管到機組168小時試運結束,在實際燃用煤質有時變差,但等離子體的點火效果仍比較好。

      (5)陰極壽命較長:陰極的使用平均壽命在146小時左右,不需要頻繁的更換陰極,而1#~4#爐的等離子體發生器的陰極壽命一般不足30小時。
