The flue gas analyzer works on the basis of selective absorption of infrared by certain gases. A new online intelligent industrial profiler using single light sources, single tube-separated semi-gas chambers and advanced serial membrane microsounders separated from the new micromechanical monophone technology. Most gas molecules are in infrared bands for vibration and rotation. When the frequency of injecting infrared radiation is the same as that of vibrating and convulsing characteristics of molecules, infrared radiation is absorbed by gaseous molecules, causing a decline in radiation intensity. Infrared gas anatomy, based on the principles of absorption of infrared radiation by the gas molecules, with high accuracy, speed and continuous measurement, etc., in the industrial sectors of steel, petrochemicals, fertilizers, machinery, etc., the flue gas analyzer is an important monitoring wrist for consumer process control; Yes.

The issue to be noted in the application of the flue gas analyzer is to ensure that the smoke and dust protection glass is kept clean and that if the lens is infected, the light recovered and the lanterns admitted are weakened and the flag light entered will land. Through the process filter, the wind cleaner or instrument gas can hold the camera clean 2. Assuming that the input of the flag light is not suitable for the limits, the calibration of the power of the light is required for L and S. After mediation, a check is required to check if the zero point is abnormal, assuming that the zero point runs and can be adjusted to zero by means of process bits Z and x. After the previous step, the entry of the flag light is not too much to ask for, and the process of cutting the gain jump can further increase or reduce the input of the flag light. It is also possible to mediate the launch angle of the laser through a process.

The smoke analyzer collects particles in the pipe by the speed sample weight method such as skin hosting, the positioning electrolytic method determines the harmless gas in the pipe and the dry wet ball method determines the amount of humidity in the pipe. They can be applied to local sampling of particulate matter and harmless gas concentrations in pipeline sources such as environmental monitoring, labour maintenance, industrial hygiene, plant mining, etc., as well as to the evaluation and calibration of the accuracy of continuous measuring instruments for flue gases. (b) System composition of the flue gas analyzer: 1. Continued monitoring of the subsystem of solid particles and rejection of laser backscatter single-point monitoring. 2. Gaseous pollutants continue to monitor the subsystems ' multi-assembly sub-gas profiler. 3. The flue gas parameters of oxygen content, flue flow, pressure, temperature, humidity, etc., continue to monitor the subsystems. Data disposal and short-distance communication systems.

The portable infrared flue gas analyzer is a physical analyzer based on the principle of infrared absorption of gases (or liquids, solids) that can be measured continuously, with a wide range, high accuracy, high flexibility and good selectivity, and is thus widely used in industrial consumption. The tectonic composition of the portable infrared flue gas analyzer: 1. There are two types of light sources in the light source radiation area, one single source and the other dual source. A single light source, provided that there is only one light element, enters the reference chamber and the sample room through two mirrors that form a set of equivalent energy beams. The two-light source structure, on the other hand, is one light source for the reference and sample rooms, respectively. Double-light sources cause error due to different heat and light. The task of the light source is to generate two energy bands with a certain frequency (2~12Hz) that are equal and stable.

Infrared flue gas analyzers are applicable to all types of industrial stoves or chimneys; The environmental maintenance industry; Engines; Boiler monitoring; Energy monitoring function; Metallurgy industry; Thermal power industry; Building materials silicate industry; Energy conservation monitoring of petrochemicals, etc. Infrared flue gas analyzers, which are used to determine the parameters for each elimination in the flue gas, are ideal equipment for boiler calibration, optimize the efficiency of extinguishing, save energy and control emissions. Infrared flue gas analyzer product characteristics: 1, multi-channel, multi-assembly subgas analyzer. 2. MLT3: zui plus four measuring channels. MLT4: zui has five more Quantities. 3. NDIR non-colour dispersed infrared detectors: microflow sensors or solid-state detectors. NDUV/VIS non-colour dispersed ultraviolet/visible light detector: semiconductor detector or vacuum secondary tube. 5, O2 Oxygen detector: Quick.

1. Before opening, check whether the cable and gas line is normal, broken or loose. 2. Once on, check if the airway is open and check if the condensation is able to block the drain. 3. Check the air cover of the apparatus after it is turned on to ensure that the flue gas does not leak in the airways. (Check the air cover of the instrument, which is capable of blocking the vent, if the sample flow of the instrument is reduced to zero within 2min, indicating that the air cover is satisfactory. 4) When preheating, hand-to-hand contact the upper end of the dryer to feel whether the built-in cooler can be cooled, or to see if the signal lights are scintillated after the instrument is operational. 5. When preheating, check to see if the reptile pump can be rotated and properly drained. 6. After preheating, check if the display screen readings on the instrument ' s mainframe are normal and if the internal pumps and fans of the instrument can be rotated. Seven, if anything.
