IV. Working Principle
GE RS-FS-9009-03 UV dry-type flame detector works based on the ultraviolet spectrum photoelectric detection principle. Its core relies on a silicon carbide high-sensitivity photoelectric sensing unit to specifically capture the 190-290nm exclusive ultraviolet spectral signals released during fuel combustion, serving as the core sensing equipment of the industrial combustion safety system. After power-on, the equipment automatically completes hardware self-inspection, sensing initialization, parameter calibration and signal matching, and enters a normalized flame monitoring standby state after successful self-inspection.
When the fuel in the furnace burns normally, the flame continuously radiates exclusive ultraviolet spectrum. The equipment sensing unit accurately captures the spectral signals, eliminates invalid signals such as ambient stray light and electromagnetic interference through a narrow-band filter circuit, and accurately determines that the flame is in a stable combustion state through intelligent signal conditioning and threshold judgment algorithm. It synchronously outputs 4-20mA analog signals corresponding to the intensity and closed switch signals, uploads them to DCS, PLC and combustion control systems, feeds back normal combustion working conditions and allows continuous equipment operation.
When fault conditions such as flame lift-off, flameout and fuel interruption occur, the furnace ultraviolet spectral signals disappear or decay sharply in an instant. The equipment quickly identifies sudden working condition changes, triggers fault judgment within the specified delay, immediately disconnects the interlock switch signal, resets the analog output to zero, and synchronously outputs fault alarm signals, driving the system to perform safety interlock actions such as fuel cut-off, furnace purging and equipment shutdown, avoiding major safety accidents such as deflagration and furnace explosion caused by fuel accumulation after flameout. The equipment monitors hardware working conditions and signal status in real time throughout the operation, actively alarms and locks in case of abnormalities, ensuring continuous reliability and controllable safety of the monitoring system.
