LGT-106 Stack Gas Analyzer Extractive type

LGT-106 stack gas analyzer is a flameproof bypass type tunable laser gas analyzer for industrial on-line analysis and environmental on-line monitoring, especially suitable for high temperature, high humidity, high dust, high pressure, harsh working conditions and small pipes where in-situ analyzer is not applicable. It can online  analyze O₂, CO, NH₃, CO₂, CH₄, H₂O, HCl, HF and other gases of various complex conditions (NOTE: A single analyzer only can analyze 1~2 components). Measuring concentration range from major to trace.

Technical Characteristics

• High selectivity

TDLAS is high resolution spectrum technology, due to the "fingerprint" characteristics of the spectrum, it is not affected

by the interference of other gases. This feature compared with other methods molecularhas obvious advantages

• High versatility

TDLAS is an effective general technology to all activist withinfrared absorption. Only need to change laser and standard
gas, the same instruments can be convenient to measure the other components. Based on this characteristic, it can be
easily changed to multi-component measurement instrument.

• High sensitivity

TDLAS has the advantages of rapid response speed and high sensitivity. In the case of not losing sensitivity, its time
resolution can be found in ms level.

 System Configuration

LGT-106 laser gas analyzer consists of transmitter, receiver and gas cell. The transmitter drives the tunable diode to emit laser of certain wavelengths, which passes through the gas cell, then reaches the receiver. The receiver performs signal processing to obtain second harmonic signal, then calculates the concentration according to the relationship between the second harmonic signal and the gas concentration.

Gas Path

Extracted by a jet pump, the sample gas is filtered(get rid of dust), heated(avoid condensation), cooled(for high temperature condition), then reaches analyze module to be measured. Shutting off ball valve and analyze module, the analyzer carries out a calibration to ensure accuracy. Shutting off ball valve and opening back-flush valve ensures gas path unblocked.
Configuration of LGT-106 is different in different situations. For example, for high pressure situation, a relief valve is added and air pump is removed. For high temperature situation, the heat tracing temperature is higher.
