KROM SCHRODER燃燒控制單元PFU760系列產品介紹
燃燒器控制單元PFU 760可控制，點燃和監(jiān)視燃氣燃燒器的間歇性或連續(xù)性。由于采用全電子設計，它們可以對各種工藝要求做出快速反應，因此也適合頻繁的循環(huán)操作。
PFU 760可用于直接點火的工業(yè)燃燒器。
燃燒器可以是調節(jié)的或階段控制的。
在工業(yè)爐上，PFU 760承擔僅與燃燒器有關的任務，從而減輕了中央爐控制的負擔，例如，它確保燃燒器在重新啟動后始終在安全的狀態(tài)下點燃。
燃燒器控制單元用于帶有機械燃燒空氣供應的燃燒器，其中風扇由單獨的邏輯控制，用于大氣燃燒器。
燃燒器控制單元PFU 760L上的空氣閥控制可協(xié)助爐子控制冷卻，吹掃和輸出控制任務。
程序狀態(tài)，設備參數(shù)和火焰信號水平可以直接從設備中讀取。燃燒器可以手動控制，以進行調試和診斷。
如果燃燒器控制單元的本地要求發(fā)生變化，則可以使用光接口將PC軟件BCSoft調整為應用程序的單元參數(shù)。
方便的輸入和輸出信號可視化系統(tǒng)以及錯誤歷史記錄為服務人員提供了支持。
為了減少安裝和布線成本，ElsterKromschr?der提供了現(xiàn)場總線接口PFA 700，以通過PROFIBUS-DP傳輸控制信號和反饋。
The burner control units PFU 760 control, ignite and monitor gas burners for intermittent or continuous operation. As a result of their fully electronic design they react quickly to various process requirements and are therefore also suitable for frequent cycling operation.
The PFU 760 can be used for directly ignited industrial burners.
The burners may be modulating or stage-controlled.
On industrial furnaces, the PFU 760 reduces the load on the central furnace control by taking over tasks that only relate to the burner, for example it ensures that the burner always ignites in a safe condition after it has been restarted.
The burner control unit is used for burners with mechanical combustion air supply where the fan is controlled by a separate logic and for atmospheric burners.
The air valve control on the burner control unit PFU 760L assists the furnace control for cooling, purging and output control tasks.
The program status, the unit parameters and the level of the flame signal can be read directly from the unit. The burner can be controlled manually for commissioning and diagnostic purposes.
If the local requirements on the burner control unit change, the PC software BCSoft can be adjusted to the unit parameters of the application by using the optical interface.
The service personnel is supported by a convenient visualization system of the input and output signals and the error history.
To reduce the installation and wiring costs, Elster Kromschr?der offers the field bus interface PFA 700 to transfer the control signals and feedbacks via PROFIBUS-DP.
