Overview

The GasTDL-3100 laser gas analyzer is based on TDLAS technology and has fast response (T90 ≤ 1s), high accuracy, and strong anti-interference ability. Its in-situ injection design does not require sampling pretreatment and can stably measure gases such as H2S, O2, CO, etc. under harsh conditions such as high temperature and high dust. The product has passed explosion-proof certification and is widely used in industrial safety and process control scenarios such as coal powder silos, blast furnaces, and converters, helping to improve production efficiency and safety.

Product Details

Product Name: Laser Gas Analyzer

Product Model:GasTDL-3100

Product Overview

GasTDL-3100Laser gas analyzerIt is a high-performance optical analysis instrument based on Tunable Semiconductor Laser Absorption Spectroscopy (TDLAS) technology, with a cross beam design, which can be used for industrial process gas control; Its response time is fast, usually calculated in seconds in in-situ measurement, avoiding the time delay caused by sampling measurement, and can timely reflect the measured gas concentration online.

Product Features

Using TDLAS technology, the measured gas is not affected by background gas interference
In situ installation, no need for sampling preprocessing system
Quick response (T)₉₀≤1s)， Real time reflection of gas concentration
Real time online measurement, gas concentration not easily distorted, high measurement accuracy
Has good adaptability in harsh measurement environments such as high temperature, high dust, high moisture, high corrosiveness, and high flow rate
Explosion proof design with high safety factor
Simple construction, no movable components, no loss components, maintenance free

Application field

① Coal mill outlet and coal powder bin for coal injection process (safety monitoring to prevent explosion)

② After the electric tar catcher of the coke oven process (safety monitoring to prevent explosions)

③ Bag filter outlet for blast furnace process (safety inspection, gas composition and calorific value detection), hot air main (monitoring combustion status, regulating device, optimizing production), hot blast furnace exhaust gas (controlling combustion efficiency), and exhaust chimney (online monitoring of exhaust emissions)

④ Before/after the induced draft fan of the converter process (safety monitoring, gas recovery), after the secondary Wen dust removal (steelmaking control, regulating device, optimized production), before and after the gas cabinet (safety control)

⑤ Heating section and exhaust pipe of heating furnace process (process control to improve production efficiency)
