CEMS flue gas sampling and analysis heating pipe is used to measure the emission of flue gas. During the combustion of coal, SO2, NO, CO and other gases will be generated. When CEMS is in the process of sampling gas, when the flue gas temperature drops to a certain value, the steam in it Will condense into water. SO2 can react with water and generate sulfurous acid. If there is water in the sampling pipeline, it will not only affect the measurement accuracy, but also seriously affect the service life of the analytical instrument. To ensure that the steam in the flue gas does not condense, the temperature must be above the condensation point. In order to prevent the steam in the sampling tube from condensing into water, the sampling tube has a heat tracing device. How to control the temperature is particularly important.
At this time, the heat pipe technology used determines the required temperature, power and application area, as well as the choice of external protective cover. All models of heat tracing tubes are suitable for use in explosion-hazardous areas. The CEMS flue gas sampling analysis heat tracing pipe is used to transfer gaseous media from the sampling location (such as the chimney, the engine, the connector of the heat tracing sampling probe) to an analytical measuring instrument (mass spectrometer, gas chromatograph, etc.). Fixed installation in equipment or as a mobile system.
CEMS flue gas sampling and analysis heat tracing composite pipe is a composite body that combines multiple functions and integrates multiple functions:
Sampling: multiple types and materials of sampling tubes can be combined;
Heat tracing: self-adjusting power, automatic compensation, heat tracing and insulation, and efficient heat insulation;
Electric control: It can be equipped with instrument signal cable, compensation cable and control cable to meet the requirements of instrument display and monitoring, which has created conditions for centralized computer control; safety fire protection, leakage protection, anti-static, electromagnetic shielding.
