A brief analysis of the three major applications of the flue gas analyzer 1. The flue gas analyzer is an instrument for measuring the smoke in automotive exhaust gas.
2. The flue gas analyzer is mainly used for the determination of diesel engine exhaust gas. A piston pump is used to draw a certain volume of exhaust gas from the exhaust pipe of the diesel engine at a predetermined time, and pass it through a certain area of ​​filter paper. The soot particles in the exhaust gas are trapped on the filter paper and the filter paper is dyed black. The absorbance of the filter paper is measured by an electro-optical measuring device, which indicates the degree of smoke in the exhaust gas.
3. The flue gas analyzer is mainly composed of a piston pump, a sampling device and an optoelectronic measuring device. The measurement is generally repeated 3 times, and the arithmetic average is obtained as the measured smoke value. Smoke values ​​range from 0-10, blank filter paper smoke is zero, and all black filter paper smoke is 10.
The main method used by the flue gas analyzer:
Direct suction sampling method (non-dispersive infrared absorption method, ultraviolet absorption method) (accounting for 9.5%, mainly Japanese products, domestic products such as Shenzhen Ang Electronics Co., Ltd.);
Dilution gas sampling method (including in-duct dilution and flue dilution, accounting for 85.5%, mainly European and American products, domestic products such as Shenzhen Ang Electronics Co., Ltd.);
Online direct measurement method (a beam of infrared or ultraviolet light is directly irradiated to the flue gas and measured using the characteristic absorption spectrum of SO2). In addition, the domestic Shenzhen Angwei Electronics Co., Ltd. has similar products.
