Product introduction
The FIREYE 45UV5-1009 is a state-of-the-art self-checking ultraviolet (UV) flame scanner produced by FIREYE, a globally recognized leader in the field of flame safeguard and combustion control. This sophisticated device is purpose-built to accurately and reliably detect the presence or absence of flames that emit ultraviolet radiation, which is characteristic of various fossil fuels including natural gas, propane, methane, butane, kerosene, and light petroleum distillates. The FIREYE 45UV5-1009 serves as a cornerstone in ensuring the safe and efficient operation of industrial burners, boilers, process ovens, and heaters by providing instantaneous and precise flame status information.
At its core, the FIREYE 45UV5-1009 utilizes a sealed, gas-filled, UV-sensitive tube with two electrodes. When exposed to sufficient UV radiation from a flame, the gas between the electrodes becomes conductive, creating a measurable electric current. A defining characteristic of the FIREYE 45UV5-1009 is its integrated electromagnetic shutter. This mechanism facilitates a continuous self-checking circuit that periodically verifies the operational integrity of the scanner and its associated signal pathways. This advanced diagnostic capability significantly enhances overall system reliability by confirming the scanner’s own health, which is particularly crucial in continuously fired applications where traditional recycling for self-testing is infrequent. The FIREYE 45UV5-1009 integrates seamlessly with compatible FIREYE controls, such as the BurnerLogix, D-Series, FlameWorx, MicroM, and E-Series platforms, offering a robust and dependable flame safeguard solution for supervised manual, semi-automatic, and fully automatic single-burner systems. The FIREYE 45UV5-1009 is designed for durability and precision, making it an essential component for critical combustion safety applications.
Core advantages and technical highlights
The FIREYE 45UV5-1009 self-checking UV flame scanner offers a compelling suite of advantages and technical highlights, establishing it as a premier choice for rigorous industrial flame detection requirements. Engineered by FIREYE, a name synonymous with combustion safety, the FIREYE 45UV5-1009 is a testament to robust design, precise performance, and advanced diagnostic capabilities.
Unmatched Self-Checking Reliability: A key differentiator of the FIREYE 45UV5-1009 is its integrated self-checking function. It incorporates an electromagnetic shutter that periodically interrupts the UV detector’s view of the flame. During this brief interruption (approximately 0.4 seconds closed every 4 seconds cycle), the associated control system verifies the proper operation of the UV tube and the entire signal processing chain. This continuous, automated self-diagnosis significantly mitigates the risk of undetected scanner failure, providing an unparalleled level of safety assurance, especially in critical applications with infrequent burner cycling. This feature ensures that any internal fault in the FIREYE 45UV5-1009 is promptly identified, preventing unsafe conditions.
Superior Flame Discrimination and Sensitivity: The FIREYE 45UV5-1009 employs a highly sensitive UV-eye detector, optimized for the 2200 to 2600 Angstrom range of the electromagnetic spectrum, which is characteristic of UV emissions from hydrocarbon flames. This precise spectral sensitivity allows the FIREYE 45UV5-1009 to effectively ignore visible light and infrared radiation, common sources of false alarms with less sophisticated scanners. The inclusion of a plano-convex quartz lens further enhances its optical performance and sensitivity, enabling accurate flame detection even at distances up to 72 inches (1830mm) and in challenging sightline conditions.
Robust and Durable Construction: Designed for the harsh realities of industrial environments, the FIREYE 45UV5-1009 features a rugged cast aluminum housing, sealed with an oil-resistant gasket. This construction provides exceptional protection against dust, moisture, and high temperatures, contributing to its longevity and reliability. With an operating temperature range of -40°F to 200°F (-40°C to 93°C), the FIREYE 45UV5-1009 can withstand extreme conditions, ensuring continuous performance where other sensors might fail. The 1″ NPT threads facilitate secure and standard mounting.
Optimized System Integration: The FIREYE 45UV5-1009 is specifically designed for seamless integration with a wide range of FIREYE burner management systems, including BurnerLogix, D-Series, E-Series, FlameWorx II, and MicroM. This native compatibility simplifies wiring, reduces commissioning time, and ensures optimal communication between the scanner and the main control, creating a cohesive and highly effective flame safeguard system. The shutter drive circuitry is integrated within the scanner itself, simplifying field wiring.
Typical application scenarios
The FIREYE 45UV5-1009 self-checking UV flame scanner is a cornerstone safety device deployed across diverse industrial landscapes where reliable combustion monitoring is paramount. Its capability to precisely detect UV emissions from fossil fuel flames makes it indispensable for a multitude of critical applications.
In power generation facilities, including industrial boilers and utility steam generators, the FIREYE 45UV5-1009 is extensively utilized to monitor both pilot and main flames. This ensures continuous flame supervision, enabling rapid detection of flame failure and initiating safe shutdown procedures to prevent the dangerous accumulation of unburned fuel, thereby mitigating explosion risks. For instance, in a large natural gas-fired power boiler, the FIREYE 45UV5-1009 would confirm stable flame presence, crucial for maintaining consistent steam production and overall plant safety.
Process heating applications represent a significant area of deployment for the FIREYE 45UV5-1009. This encompasses a broad range of industrial equipment such as kilns, industrial ovens, thermal oxidizers, and dryers used in sectors like petrochemicals, pharmaceuticals, food processing, and automotive manufacturing. In a continuous industrial drying oven, the FIREYE 45UV5-1009 ensures that the drying process maintains the necessary heat from a stable flame, preventing product damage and ensuring the safety of the operating environment by detecting any flame out condition.
Furthermore, the FIREYE 45UV5-1009 is a vital component in commercial and institutional heating systems that employ burners firing natural gas, propane, or light fuel oils. This includes large-scale HVAC systems, water heaters, and institutional boilers found in hospitals, universities, and commercial complexes. The self-checking capability of the FIREYE 45UV5-1009 is particularly beneficial in these settings, as it provides an automated layer of diagnostic reliability, reducing the need for manual checks and ensuring consistent heating and safety across the facility. Its robust design is well-suited to the continuous duty often required in these applications.
