Fourier smoke toxicity analysis system

The Fourier Smoke Toxicity Analysis System (FSTAS) is an experimental setup for assessing the toxicity of hazardous gases and smoke in combustion products. 

Objective:

The main purpose of the Fourier Smoke Toxicity Analysis System is to analyze the toxicity of smoke produced during combustion processes, and in particular to detect the types and concentrations of hazardous gases in order to assess the risk of toxicity in fire scenarios.

Structure:

A Fourier smoke toxicity analysis system typically consists of the following components:

1.Gas Sampling System : Gas samples from combustion products are collected and analyzed for detection.

2.Smoke Analysis Device : Used to analyze the concentration of smoke components and hazardous gases in the gas samples, usually using chromatography or spectrometry and other technologies.

3.Data Acquisition System (DAS): Used to record and analyze the data output from the Smoke Analysis Device, including information on the type, concentration, and emissions of hazardous gases.

Test Process:

1.Gas Sampling: Gas samples from the combustion products are collected by the Gas Sampling System and fed into the Smoke Analysis Unit for analysis.

2.Smoke Analysis: The smoke analysis unit analyzes the gas samples to identify and measure the harmful gas components such as carbon monoxide, carbon dioxide, hydrocyanic acid, etc. in them.

3.Data Recording and Analysis: The smoke analysis unit outputs data that is recorded and analyzed by the data acquisition system to determine smoke toxicity and harmful gas concentration.

Test Parameters:

The main parameters considered by the Fourier Smoke Toxicity Analysis System include:

• Types of Hazardous Gases : the types of hazardous gases that may be present in the smoke, such as carbon monoxide, hydrocyanic acid, and so on.

• Concentration of Hazardous Gases : Concentration of various hazardous gases in the smoke, reflecting the degree of toxicity of the smoke.

• Emission Rate: The emission rate of various hazardous gases in the smoke, which is used to assess the degree of pollution in the combustion process.

Application:

The Fourier Smoke Toxicity Analysis System finds extensive use in various industries such as construction, automobiles, and electronic products. It determines the toxicity of smoke and the concentration of harmful gases in fire situations. It helps in developing fire safety designs and protective measures.

Advantage:

The Fourier Smoke Toxicity Analysis System offers the following advantages:

• High sensitivity: capable of detecting and analyzing very low concentrations of harmful gases in combustion products.

• Rapid analysis: able to monitor the harmful gas components in smoke in real time, providing timely data support.
