Embodiment Construction

[0085] Next, a multi-component laser gas analyzer according to Embodiment 1 for carrying out the present invention will be described below with reference to the drawings. figure 1 It is an overall configuration diagram of the multi-component laser gas analyzer of the present embodiment.

[0086] The multi-component laser gas analyzer 1 of the present embodiment is concerned with oxygen gas (hereinafter referred to as O) contained in the gas flowing through the walls 50a and 50b, which is the first gas to be measured. 2 gas) and the gas concentration of carbon monoxide gas (hereinafter referred to as CO gas) which is the second measurement target gas. In addition, if the gas concentration is 0 or less than a predetermined value, it is a case of detecting the absence of gas, and the presence or absence of gas can also be detected.

[0087] In detail, the multi-component laser gas analyzer 1 includes a light emitting unit 10 , a light receiving unit 20 , and a communication lin...

Abstract

Provided is a laser gas analyzer for measuring an O2 gas concentration and a CO gas concentration simultaneously, at high speed, high precision, high sensitivity, and high stability by a single device. A multicomponent laser gas analyzer in which a first detection light passing through a broadband condensing lens and a through-hole of a parabolic mirror provided with a hole for a light emitting part in a certain period is received by a broadband light-receiving element, a second detection light passing through the broadband condensing lens and the through-hole of the parabolic mirror provided with a hole for a light emitting part in another period is received by the broadband light-receiving element, and an O2 gas concentration and a CO gas concentration are each separately measured on the basis of first and second detection signals received for each period from the broadband light receiving element.

Description

technical field [0001] The present invention relates to a multi-component laser gas analyzer for analyzing the presence and concentration of various measurement target gases in a space. Background technique [0002] Laser gas analyzers are used, for example, to monitor the combustion state of high-temperature combustion gases in heat treatment in petrochemical plants and thermal power generation. The parameter of the combustion state is usually the O in the exhaust composition 2 (oxygen) gas concentration and CO (carbon monoxide) gas concentration. This point will be described with reference to the drawings. Figure 5 It is a characteristic diagram showing the relationship between the excess air ratio in the burner and the gas concentration. In addition, as the patent document 1 described later figure 2 and made public the Figure 5 . From this characteristic diagram, the following can be seen. [0003] (a) As the excess air ratio increases, that is, the oxygen increas...
