The SPECTRA BC11 Flame Sensors provide maximum performance and reliability using advanced solidstate design and high performance optical detectors.

Single IR detectors use high tech pyroelectric sensors that have a micron optical and an electronic bandpass filter to gas fires and carbonbased fuel. The device is also sensitive to CO2 emissions. The reason why they are so effective is that they use various mathematical techniques and parameter analysis to distinguish between flame spectral signatures and other infrared sources.

optical flame and gas detection systems be installed at their facilities to detect and/or mitigate a catastrophic fire, explosion, or toxic gas release. Prior to selecting an optical flame detector, users must assess the fire hazards and scenarios present, understand the principles of optical flame detection, and specify the appropriate detection technology from the many options available ...

20060701· The method is an alternative to existing optical flameout sensors which are susceptible to false flameout indications due to window sooting. This paper compared an optical flame sensor, a laboratory photodiode sensing system, and a production EGT thermocouple with online electronic processing. These devices were tested in a full scale GE J85 combustion chamber sector rig with …

This article provides the basic guidelines for the selection of fire and gas detectors like linear heat detector, rate of rise heat detector, optical smoke detector, ionization chamber smoke detector, open path gas detector, catalytic sensor type combustible gas detector, and flame detector.. Selection of Fire and Gas Detectors. Linear Heat Detector. The linear heat detectors shall sense an ...

Selection of an analyzer for monitoring kilns leads either to a flame ionization or flame temperature detector. Non‐dispersive infrared sensors are limited in operating temperature and cannot be accurately applied to the broad range of combustibles found in kilns. The two detector types most likely to produce a satisfactory response both use a sensing flame. Of these two, the flame ...

An optical flame detector is composed by ultraviolet (UV) and infrared (IR) sensors. The most efficient flame detectors usually feature several sensors (UV, UV/IR, IR3 or IR4). Just like a fixed gas detector, an optical flame detector usually works in connexion with a gas controller unit. Most of our optical flame detectors are SIL2 approved.

Optical flame detectors produced by Oldham are divided into 4 sensor categories: UV that analyze radiations, IR sensitive to CO2 radiation, UV/IR which is a combination of the two previous technologies and IR3 to avoid solar radiations interferences. Thanks to these different flame detection technologies, Oldham optical flame detectors fit in any activity zone with efficiency, reliability and ...

Flame sensors are crucial to the safe operation and maintenance of harsh, high temperature gas turbines and fired process equipment such as steam methane reformers, boilers, drying kilns and industrial ovens. Fired process equipment and gas turbines for power generation use combustible fuels such as natural gas, diesel, and refinery gas. Flame supervision when using such combustible fuels is ...

20180401· Optical flame imaging was performed at different fuel gas compositions and air equivalence ratios. • Two methods were used: flame imaging and flame scannng. • Flame imaging was performed through optical bandpass filters. • Flame scanning was performed by 5 optical fibers coupled to spectrometer. • Dependence on fuel gas composition and air equivalence ratio was analysed. …

20040910· Flame rod detectors are used with flame safeguard controls on industrial or commercial gas burners or oil burners with gas pilots. The flame rod and flame safeguard system use a very small amount of current. This sensing current is actually conducted by and through the flame, which acts as a rectifier. The flame rod sensor and the burner, which is at ground potential, are the sensing ...
