A flame detector is a sensor designed to detect and respond to the presence of a flame or fire, allowing flame detection. Responses to a detected flame depend on the installation, but can include sounding an alarm, deactivating a fuel line (such as a propane or a natural gas line), and activating a fire suppression system.
Flame ionization detectors cannot detect inorganic substances and some highly oxygenated or functionalized species like infrared and laser technology can. In some systems, CO and CO 2 can be detected in the FID using a methanizer , which is a bed of Ni catalyst that reduces CO and CO 2 to methane, which can be in turn detected by the FID.

With this type of firing, combustion is extremely rapid, and short flame length results. The mixing is so intense that combustion rates exceeding 35,000 Btu/(ft 3 ·h) or 360 kW/m 3 are practical under certain conditions.

[1] [2] It is a type of flame thermionic detector (FTD), the other being the alkali flame-ionization detector (AFID also known as AFD). With this method , nitrogen and phosphorus can be selectively detected with a sensitivity that is 10 4 times greater than that for carbon .
A TOP-SENS2 ASD unit made by Wagner (Germany) An aspirating smoke detector (ASD) is a system used in active fire protection, consisting of a central detection unit which draws air through a network of pipes to detect smoke. [1]
