What Is Stack & Stack Emission Testing

Stack Emission Testing
  • A stack is a large industrial chimney that is designed to emit and discharge hot exhaust air, particulate matter, and products of combustion; into the air. The heights of these chimneys are purposefully kept high, so that the released matter, gases, fumes, and vapours from the industries are not discharged near the surface of the land, and therefore do not pose any sort of danger to the living surrounding.

Listed are the stacks used by huge industries:

  1. Boiler stacks
  2. Flue gas stacks
  3. Furnace stacks
  4. DG set stacks
Stack Emission Testing
  • Stack emission testing is also known as ‘Source Sampling Test’, ‘Emission Test,’ ‘Compliance Test’ and ’ Performance Test.’ The test methods vary depending upon the industry and type of pollutants released. Performing stack emission testing ensures that the industry is compliant with regulated emission limits in your permit.
  • The stack emission testing is majorly performed on boiler stacks, exhausts from printers, discharges from bag filters, thermal oxidizers, etc.

Need of Stack Emission Testing Labs in India

Stack Emission Testing
  • To monitor the emission dispersed from the stack is a mandatory requirement for all the companies of India; this is put on record in many ‘environment agencies’ and ‘local authority permits.’ The requirement for stack emissions testing is gauged from the environmental impact a business is doing.
  • The testing helps the inspectors, facility managers, and other stakeholders to check the amount of industrial waste and pollutants generated from the stack. The accurate emission data gathered from the test results give the industry an upper hand when it comes to proving that your industry complies with the instructions laid by the regulatory bodies.
  • The data obtained from the testing result also helps in obtaining engineering data for pollution control. This engineering data helps in specifying the design of the control equipment and in testing the efficiency of the control equipment.

Following Tests Are Performed For Stack Emission Testing

  • The test methods entirely depend on the industry type and the number of pollutants released.  The specified tests are carried out to determine a pollutant concentration and the emission rate. 




    Particulate matter

    Sulphur dioxide

    Oxides of Nitrogen

    Carbon monoxide




    Carbon dioxide

    Acid Mist (H2SO4)

    Flow rate
