    Phoenix火焰掃描儀通過監測火焰的振幅來確定是否存在火焰

    火焰的閃爍頻譜很寬。最初應安裝掃描儀,以便主燃燒區位于掃描儀的視線范圍內。

    以下各節中列出的位置和瞄準說明是位置的大致指南掃描儀的。掃描儀通過LED和4-20ma輸出提供反饋,以協助調整

    以及火焰掃描儀的正確對準。請參閱本維修通訊中描述的設置程序。

    DS200SLCCG1AFG燃機模塊注:可接受的掃描儀位置必須確保以下各項:在所有氣流和爐膛負荷(范圍)下可靠的主火焰和/或點火器火焰檢測燃料燃燒)。

    如果太短或位置錯誤,無法點燃主火焰,則拒絕點火器火焰可靠,從而禁止向燃燒器輸送燃料。

    注:確保在調試前選擇正確的FFRT(火焰失效響應時間)1。當掃描器瞄準時,掃描器的視線以微小角度(例如5度)與燃燒器中心相交,并能看到最大的一次燃燒區,如圖3所示。如果每個燃燒器僅使用一臺掃描儀,則視線還應與點火火焰相交。

    對于使用單獨掃描儀監測主火焰和點火器火焰的裝置,主火焰應看到火焰掃描儀,使其無法檢測到點火器火焰。

    3、掃描儀應盡可能不受限制地查看火焰。物理障礙物如空氣調節器葉片、干擾葉片或其他硬件應切掉或開槽,以便它們不在掃描儀的視線范圍內

    The Phoenix flame scanners determine the presence or absence of flame by monitoring the amplitude of

    the flame across a wide flicker frequency spectrum. The scanner should initially be mounted so that the

    primary combustion zone is within the scanner’s line of sight.

    The location and sighting instructions listed in the following sections are rough guidelines for the location

    of the scanner. The scanner provides feedback via LEDs and the 4-20ma output to assist in the adjustment

    and proper alignment of the flame scanner. Refer to the set-up procedures described in this bulletin.

    Note: An acceptable scanner location must ensure the following:

    Reliable main flame and/or igniter flame detection at all air flow and furnace loads (ranges

    of fuel firing).

    Rejection of the igniter flame if too short or in the wrong position to ignite the main flame 

    reliably, thus prohibiting the delivery of fuel to the burner.

    Note: Ensure the correct FFRT (Flame Failure Response TIme) is selected prior to commissioning1. The best results are obtained when the scanner is aimed so that the scanner’s line of sight intersects the burner center at a slight angle (e.g. 5 degrees) and sees a maximum of the primary

    combustion zone, as shown in Figure 3. If only one scanner is used per burner, the line of sight

    should also intersect the igniting flame.

    2. For installations where separate scanners are used to monitor main and igniter flames, the main

    flame scanner should be sighted so it does not detect the igniter flame.

    3. The scanner should have an unrestricted view of flame as far as possible. Physical obstructions

    such as air register blades, interfering vanes, or other hardware should be cut away or notched so

    they do not fall within the scanner’s line of sight
