Introduction

The detection or monitoring of flue gases and or hazardous gases has been a complex subject and makes choosing an appropriate gas monitoring instrument a difficult task. Emission monitoring are legal requirements governing air pollutants

released into the atmosphere. Emission standards set quantitative limits on the permissible amount of specific air pollutants that may be released from specific sources over specific timeframes. They are generally designed to achieve air quality standards and to protect human health. Furnaces, heaters, boilers burn fuel in the presence of oxygen and produces flue gases. Scrubbers in continuous process industries release toxic or hazardous gases. In event of solvent handling process industries, combustible or flammable vapors are present at working places.

In case of Furnaces, heaters, boilers, achieving an intelligent balance of fuel and air will provide the most efficient combustion and highest cost savings.

For Scrubbers, release of toxic or hazardous gases in air, continuous analysis and or monitoring achieve regulating it and protect environment.

In process industries, solvent vapor or hazardous gases leakage is a common problem. The

combustible mixture present at work environment can lead to fatal fire and explosion. A flame proof

gas detector installed near probable leakage places, which measure %LEL at work place, can control such situation.

There is a growing need for more comprehensive gas analysis in line with rising public concern over the effects of combustion exhaust gas on the global environment and the desire to conserve energy.

Static Control Consulting Engineers, has designed a cost effective, low maintenance, reliable, Online Gas Analyzer and Combustible Gas detector.
