As a general rule-of-thumb, gaseous fuels produce UV radiation and liquid\/solid fuels produce IR. However, most fuels produce a range of emissions across both the UV \u0026amp; IR spectrum meaning there is crossover when deciding on which type of flame detector to use.\u003c\/p\u003e\n\u003ctable style=\"width: 100%;\" width=\"100%\"\u003e\n\u003ctbody\u003e\n\u003ctr\u003e\n\u003ctd style=\"width: 50%;\"\u003e\n\u003ch3\u003eOptical Flame Detector\u003c\/h3\u003e\n\u003cp\u003eUV flame detectors are specialized devices in industrial combustion systems that leverage ultraviolet (UV) radiation to detect and monitor flames. These essential safety tools not only enhance system efficiency but also ensure the secure operation of combustion processes.\u003c\/p\u003e\n\u003cp\u003eEquipped with a UV-sensitive sensor, a UV flame detector is attuned to UV wavelengths emitted by a flame during combustion. This sophisticated technology captures the UV radiation, transforming it into an electrical signal. This data is then processed and scrutinized by control systems, providing valuable insights into the combustion process.\u003c\/p\u003e\n\u003cp\u003eThese detectors excel in accurately identifying the presence, stability, and characteristics of a combustion flame. They offer reliable detection capabilities even in challenging industrial conditions, such as areas with significant amounts of smoke, dust, or intense background lighting.\u003c\/p\u003e\n\u003cp\u003eUV flame detectors are indispensable in industrial combustion systems like furnaces, boilers, and gas turbines. By promptly identifying irregularities such as flameouts or suboptimal combustion, these devices facilitate immediate intervention, reducing potential risks and optimizing operational performance.\u003c\/p\u003e\n\u003cp\u003eIndustrial Combustion Systems and IR Flame Detectors: Improving Safety and Efficiency\u003cbr\u003e\u003cbr\u003eIR (infrared) flame detectors are essential safety devices in industrial combustion systems. They utilize infrared radiation, a by product of the combustion process, to detect and monitor flames, thus bolstering system safety and efficiency.\u003c\/p\u003e\n\u003cp\u003eAn IR flame detector features an infrared sensor, purposefully designed to detect the unique infrared wavelengths of combustion flames. As fuel burns and releases energy in the form of infrared radiation, the detector captures it and converts it into an electrical signal for further analysis.\u003cbr\u003e\u003cbr\u003eThese detectors distinguish between flames and other heat or infrared radiation sources by identifying unique flame signatures. This ensures accurate flame detection even in environments with high ambient temperatures or numerous heat sources.\u003c\/p\u003e\n\u003cp\u003eIR flame detectors are crucial in monitoring flame presence and stability across various industrial applications, including furnaces, boilers, and incinerators. They furnish crucial information about flame status and characteristics, thereby promoting optimal combustion, preventing flameouts, and alerting operators to abnormal flame activity or potential hazards.\u003c\/p\u003e\n\u003cp\u003eBy detecting flame anomalies swiftly and providing real-time data to control systems, IR flame detectors enhance the safety and efficiency of industrial combustion processes. This contributes significantly to risk minimization and performance optimisation.\u003c\/p\u003e\n\u003c\/td\u003e\n\u003ctd style=\"width: 50%;\"\u003e\n\u003ch3\u003eIonisation Probes\u003c\/h3\u003e\n\u003cp\u003eThe ionisation probe, also known as an ionisation rod or flame sensor, plays a crucial role in combustion systems by detecting the presence or absence of a flame. It is a vital component that ensures the safe and efficient operation of various heating and combustion processes.\u003c\/p\u003e\n\u003ch4\u003eWhat is an Ionisation probe?\u003c\/h4\u003e\n\u003cp\u003eComprised of a conductive metal rod, typically constructed from stainless steel or a suitable material, the ionisation probe is strategically positioned within the combustion chamber or near the burner flame. Once the burner is ignited, the flame engulfs the ionisation probe.\u003c\/p\u003e\n\u003cp\u003eWhen the flame interacts with the probe, it induces ionisation in the surrounding air molecules. This ionisation process causes the air particles to acquire an electric charge, resulting in the generation of ions. The conductive metal rod of the ionisation probe serves as an electrode, facilitating the flow of these ions and enabling the formation of a small electrical current.\u003c\/p\u003e\n\u003cp\u003eThe combustion system continuously monitors this electrical current to ascertain the presence or absence of the flame. If the flame becomes extinguished or goes undetected, the electrical current will decrease significantly or halt altogether. This abrupt change in current triggers built-in safety mechanisms or prompts the initiation of corrective actions to prevent hazardous conditions or unnecessary fuel wastage.\u003c\/p\u003e\n\u003ch4\u003eWhat is its purpose?\u003c\/h4\u003e\n\u003cp\u003eThe primary purpose of the burner ionisation probe is to provide reliable and rapid flame detection, ensuring optimal performance and safeguarding against potential hazards. By swiftly detecting any flame-related issues, such as flame failure, the ionisation probe contributes to the overall safety and efficiency of the combustion system.\u003c\/p\u003e\n\u003cp\u003eThanks to its ability to detect flame presence accurately and promptly, the ionisation probe acts as a vital safeguard, preventing the release of unburned fuel into the environment or the accumulation of potentially explosive gases. It enables the combustion system to maintain stable and controlled combustion, minimizing the risk of accidents, inefficiencies, and environmental harm.\u003c\/p\u003e\n\u003cp\u003eIn summary, the ionisation probe is an indispensable component of combustion systems, serving as a critical safety feature. Through the principle of ionisation, it detects the presence or absence of a flame, allowing for timely corrective measures to ensure safe and efficient operation.\u003c\/p\u003e\n\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e\n\u003cp\u003e \u003c\/p\u003e\n\u003ch3\u003eMaintaining Your Flame Safety System\u003c\/h3\u003e\n\u003cp\u003eContamination of the detector’s lens with dust or oil also affects performance. This can be alleviated with the addition of Quartz lenses in front of the sensor or with compressed air being fired over the lens to keep it clear of contaminants. More regular servicing is also required in these environments.\u003c\/p\u003e\n\u003ch3\u003eDo I Need a Self Checking Flame Detector\u003c\/h3\u003e\n\u003cp\u003eSystems can be classed as either non-continuous or continuous operation. Non-continuous operation requires that the burner be switched off at least once every 24 hours to confirm the flame detector is able to detect both states i.e. flame in\/flame out.\u003c\/p\u003e\n\u003cp\u003eSome flame detectors, for example, a UV tube, may have a non-failsafe failure mode, meaning their operation needs to be verified periodically. Continuous operation can be achieved by using a device containing a mechanical shutter that allows the detector to self-check by simulation of a no flame condition.\u003c\/p\u003e\n\u003cp\u003eMore modern flame detectors use more sophisticated methods for self-checking. A characteristic of nearly all flames is that they flicker. This is a product of the fuel type, combustion process and mechanical design of the burner. Flicker frequency tends to increase with firing rate as a result of higher air velocity and fuel mixing at the burner head or nozzle. Flicker frequency varies along the flame path dropping off significantly towards the end of the flame. This characteristic can be used to ‘tune’ a flame detector to discriminate one flame from another in multi-burner systems or to discriminate the flame from other background radiation. These more intelligent flame detectors monitor the flicker and the self-check using software rather than mechanical operation.\u003c\/p\u003e","products":[{"product_id":"flame-electrode-150mm-ph150","title":"Comtherm Flame Electrode 150mm - PH150","description":"\u003ch3\u003e\u003cstrong\u003ePH150 Electrode\u003c\/strong\u003e\u003c\/h3\u003e\n \u003cp\u003e \u003c\/p\u003e\n \u003ch3\u003eFitted to:\u003c\/h3\u003e\n \u003cp\u003eComtherm \u003cstrong\u003eEK1\u003c\/strong\u003e burners\u003c\/p\u003e\n \u003cp\u003eComtherm \u003cstrong\u003ePC1\u003c\/strong\u003e burners\u003c\/p\u003e\n \u003ch3\u003e\u003c\/h3\u003e\n \u003ch3\u003eElectrode Length:\u003c\/h3\u003e\n \u003cp\u003e150mm\u003c\/p\u003e\n \u003c!----\u003e","brand":"Comtherm Ltd","offers":[{"title":"Default Title","offer_id":43773957406974,"sku":"SPA174","price":59.08,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0638\/4028\/9022\/files\/EA150-Final.jpg?v=1753853841"},{"product_id":"flame-electrode-200mm-ph200","title":"Comtherm Flame Electrode 200mm - PH200","description":"\u003ch3\u003e\u003cstrong\u003ePH200 Electrode\u003c\/strong\u003e\u003c\/h3\u003e\n \u003cp\u003e \u003c\/p\u003e\n \u003ch3\u003eFitted to:\u003c\/h3\u003e\n \u003cp\u003eComtherm\u003cspan\u003e \u003c\/span\u003e\u003cstrong\u003eEK\u003c\/strong\u003e\u003cspan\u003e \u003c\/span\u003eburners\u003c\/p\u003e\n \u003cp\u003eComtherm\u003cspan\u003e \u003c\/span\u003e\u003cstrong\u003ePC\u003c\/strong\u003e\u003cspan\u003e \u003c\/span\u003eburners\u003c\/p\u003e\n \u003ch3\u003e\u003cbr\u003e\u003c\/h3\u003e\n \u003ch3\u003eElectrode Length:\u003c\/h3\u003e\n \u003cp\u003e200mm\u003c\/p\u003e\n \u003c!----\u003e","brand":"Comtherm Ltd","offers":[{"title":"Default Title","offer_id":43773957538046,"sku":"SPA171","price":59.08,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0638\/4028\/9022\/files\/PH200.jpg?v=1753853840"},{"product_id":"flame-electrode-300mm-ph300","title":"Comtherm Flame Electrode 300mm - PH300","description":"\u003ch3\u003e\u003cstrong\u003ePH300 Electrode\u003c\/strong\u003e\u003c\/h3\u003e\n \u003cp\u003e \u003c\/p\u003e\n \u003ch3\u003eFitted to:\u003c\/h3\u003e\n \u003cp\u003eComtherm\u003cspan\u003e \u003c\/span\u003e\u003cstrong\u003ePC\u003c\/strong\u003e\u003cspan\u003e \u003c\/span\u003eburners\u003c\/p\u003e\n \u003ch3\u003e\u003cbr\u003e\u003c\/h3\u003e\n \u003ch3\u003eElectrode Length:\u003c\/h3\u003e\n \u003cp\u003e300mm\u003c\/p\u003e\n \u003c!----\u003e","brand":"Comtherm Ltd","offers":[{"title":"Default Title","offer_id":43773957636350,"sku":"SPA173","price":76.15,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0638\/4028\/9022\/files\/PH300.jpg?v=1753853839"},{"product_id":"flame-electrode-90mm-ph90","title":"Comtherm Flame Electrode 90mm - PH90","description":"\u003ch3\u003e\u003cstrong\u003ePH90 Electrode\u003c\/strong\u003e\u003c\/h3\u003e\n \u003cp\u003e \u003c\/p\u003e\n \u003ch3\u003eFitted to:\u003c\/h3\u003e\n \u003cp\u003eComtherm\u003cspan\u003e \u003c\/span\u003e\u003cstrong\u003eEK1\u003c\/strong\u003e\u003cspan\u003e \u003c\/span\u003eburners\u003c\/p\u003e\n \u003cp\u003eComtherm\u003cspan\u003e \u003c\/span\u003e\u003cstrong\u003ePC1\u003c\/strong\u003e\u003cspan\u003e \u003c\/span\u003eburners\u003c\/p\u003e\n \u003ch3\u003e\u003cbr\u003e\u003c\/h3\u003e\n \u003ch3\u003eElectrode Length:\u003c\/h3\u003e\n \u003cp\u003e90mm\u003c\/p\u003e\n \u003c!----\u003e","brand":"Comtherm Ltd","offers":[{"title":"Default Title","offer_id":43773957669118,"sku":"SPA175","price":44.9,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0638\/4028\/9022\/files\/EA151-Final.jpg?v=1753853838"},{"product_id":"siemens-qra53-g17-flame-detector","title":"Siemens QRA53.G17 UV Flame Detector - Self Checking","description":"\u003cp\u003eQRA53.G17 - UV flame detector, continuous operation, high sensitivity, 125mm, AC110V\u003c\/p\u003e","brand":"Siemens","offers":[{"title":"Default Title","offer_id":43773982605566,"sku":"SPA214","price":989.18,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0638\/4028\/9022\/files\/flame-detector-qra53e27-siemens.jpg?v=1753853798"},{"product_id":"siemens-qra73-a17-flame-detector-110v","title":"Siemens QRA73.A17 UV Flame Detector - Self Checking","description":"\u003cmeta charset=\"utf-8\"\u003e\n \u003cp data-mce-fragment=\"1\"\u003eThe Siemens QRA73.A17 is a UV flame detector with normal sensitivity.

In the absence of UV radiation, the gas acts as an insulator between two electrodes which are mounted inside the tube. These electrodes are energised continuously by a high voltage. During combustion, UV radiation ionises the gas, causing current pulses to flow between the electrodes.
