VFunction and principle
> Gas sample—Electrochemical Analysis /Fixed potential by electrolysis method
Put the sampling probe into the stack to extract flue gas including SO2，NOx.After dedusting and dehydration treatment,through SO2,NOx electrochemistry sensor，the following reaction will happen.
SO2+2H2O —> SO4- + 4H++2e-
NO +2H2O —> NO3- + 4H++3e-
Under certain conditions, the size of the sensor output current is proportional to the concentration of SO2, NO.According to the measurement of the sensor output current ,can be calculated instantaneous concentration of SO2, NOx.At the same time, according to the test flue gas emissions parameters, instruments t can calculates SO2 and NOx emissions.
> Velocity of flow—Pitot tube method
> Temperature in flue gas—PT100 method
> Built in a solid hydrogen cylinder.
> Explosion protected and easy to replaceable
> Dust sample—isokinetic sampling & gravimetric method
velocity of flue gas entering the sampling nozzle = velocity of flue gas at the sampling point
particulate matter has a certain mass, due to its own inertial motion in the flue, it cannot completely change direction with the airflow. In order to obtain representative dust samples from the flue, isokinetic sampling is required, that is, the velocity of gas entering the sampling nozzle should be equal to the velocity of the flue gas at the sampling point, and the relative error should be within 10%. The velocity of gas entering the sampling nozzle is greater than or less than the velocity of flue gas at the sampling point, which will cause deviation in the sampling results.
> Humidity—wet and dry ball
MPU controls sensors to measure wet ball，dry ball, wet ball surface pressure and exhausted static pressure.Combined with temperature of wet ball surface temperature to trace the related saturated vapor pressure--Pbv,calculates flue gas humidity in accordance with formula.
> O2 measurement
Put the sampling probe to extract flue gas with O2 and measure instant O2 content.According to O2 content, computes air excess coefficient α.
