Abstract

The invention relates to a probe comprising a spectrometer (4) capable of measuring the composition of a combustion-supporting gas after analysis of at least one portion (F13) of a light beam having interacted with the combustion-supporting gas, the spectrometer comprising: a light source (40) capable of emitting a light beam (F), an optical device comprising optical elements (50) which are configured: to guide, towards the gas (G) to be analyzed, at least one portion (F11) of the light beam, and to guide, towards a detector (41), a portion (F13) of the light beam having interacted with the gas (G), wherein: the probe (S) comprises a cage (12) suitable for being removably installed inside a channel (C) through which the gas (G) to be analyzed flows, the cage (12) being configured to permit a flow of the gas through the cage, at least one portion (F11, F12) of the light beam propagating through the cage (12) so as to be able to interact with the gas (G), the cage (12) serving as holder for an optical reflector (51) capable of reflecting, towards the detector (41), the portion (F11, F12) of the light beam that propagates through the cage and that has interacted with the gas (G), characterized in that the cage (12) is formed by an elongate tube the sidewall of which contains apertures (120) distributed over the perimeter of the wall and configured to allow the gas to pass radially through the tube, the combined area of the apertures representing more than 50% of the area of the wall of the tube, and preferably more than 80%.

Description

technical field

[0001] The object of the invention is a probe for measuring the composition of combustion-supporting gases. The subject of the invention is also a system for measuring the composition of combustion-supporting gases comprising such a probe.

[0002] The invention relates to the technical field of real-time analysis of combustion-supporting gas components, in particular to the analysis directly in a combustion-supporting gas circulation pipeline by in-situ spectroscopy. It is particularly suitable, but not limited to, for monitoring the quality of combustion-supporting gas supplied to appliances using this gas as fuel. Background technique

[0003] The measurement of the composition of the combustion-supporting gas is particularly meaningful for monitoring the quality of the combustion-supporting gas, which is supplied to gas appliances such as gas heat engines, gas burners, gas boilers, gas turbines, and gas furnaces. In fact, the gas composition may change ...
