Stack / Boiler Emission Monitoring Accurate Emissions Testing for Clean Air, Regulatory Compliance & Responsible Operations

Boiler stacks and industrial exhausts are major sources of air pollutants. To protect human health, environment, and to comply with air quality norms, it’s essential to detect, quantify, and control stack emissions accurately. At ITS Lab, we offer comprehensive boiler and stack emission monitoring services—helping industries stay compliant, reduce pollution, and improve process efficiency.

What Is Stack / Boiler Emission Monitoring?

  • Stack emission monitoring involves sampling and analyzing the gases and particulate matter emitted through chimneys, stacks, or exhausts of boilers and industrial units. It helps measure parameters such as:

    • Particulate Matter (PM) including fly-ash & dust
    • Gaseous pollutants: SO₂ (sulphur dioxide), NOₓ (nitrogen oxides), CO (carbon monoxide), CO₂ (carbon dioxide)
    • Volatile Organic Compounds (VOCs) and other hydrocarbon emissions
    • Acid gases (like HCl, HF), heavy metals, etc.
    • Stack gas flow rate, temperature, velocity, moisture, and other physical parameters
    These parameters are compared against ambient norms and emission standards (national/regional) to assess compliance and to validate the performance of pollution control devices

Why It Matters

  • Regulatory Compliance
    Industrial boilers are subject to norms issued by bodies like Central Pollution Control Board (CPCB) & State Pollution Control Boards (SPCB), which specify permissible limits of PM, SO₂, NOₓ etc. Non-compliance can lead to fines, permit revocations, or forced shutdowns. cpcb.gov.in+2Haryana State Pollution Control Board+2
  • Public Health & Environment
    Excessive emissions contribute to air pollution, respiratory illnesses, acid rain, and environmental degradation.
  • Operational Efficiency
    Monitoring emissions helps assess whether pollution control devices (e.g. scrubbers, bag filters, ESPs) are working properly, and whether the combustion process is efficient. Inefficiencies often manifest as higher emissions.
  • Reputation & Sustainability
    Companies demonstrating low emissions and environmental responsibility gain trust among regulators, investors, communities, and consumers.



Regulatory Standards & Guidelines

  1. Some of the relevant norms and standards for boiler / stack emissions in India include:

    • CPCB emission norms for boilers (various capacities) for SO₂, NOₓ, particulate matter. cpcb.gov.in+2de.envea.global+2
    • For small boilers (less than 2 tph), larger boilers etc., limits on Particulate Matter have been specified, e.g. 150 mg/Nm³ for many standard boiler stacks under typical operating conditions. cpcb.gov.in+1
    • Regulations also set requirements for stack height, sampling ports, and the necessary physical conditions for accurate sampling. envirotechrpl.com+2Haryana State Pollution Control Board+2

Our Stack Emission Monitoring Services

  • At ITS Lab, we offer a full suite of services around stack / boiler emissions monitoring:

    • Emission Sampling & Analysis
      Site-sampling of flue gas using standard methods, at operational loads. Measurement of gas concentrations, particulate matter, VOCs, acid gases, etc.
    • Flow, Temperature & Velocity Measurements
      To compute actual emission rates, not just concentrations—these parameters are essential for accurate back-calculations and compliance reporting.
    • Continuous Emission Monitoring System (CEMS) Support
      For operations that require real-time tracking of stack emissions, we help with installation, calibration, validation or audit of CEMS.
    • Pollution Control Device Performance Check
      Verifying effectiveness of devices like electrostatic precipitators, bag filters, scrubbers, wet collectors, etc.
    • Compliance Reporting
      Providing detailed reports comparing measured values with relevant regulatory standards, with supporting data (flow, fuel usage, process conditions) to assist in environmental permits and audits.
    Consultation & Improvement Recommendations
    Based on data, help you identify where emission sources are high, suggest operational or technology improvements (e.g. switch fuel, optimize combustion, upgrade controls) to reduce emissions

Our Approach & Quality Assurance

  1. Pre-Assessment & Planning – Understanding boiler / stack type, fuel used, load conditions, process data to plan the monitoring schedule.
  2. Proper Sampling Port & Setup – Ensuring correct sampling ports, platform access, safety, representative sampling location & conditions.
  3. Instrument Standardization & Calibration – Using calibrated instruments, validated methods, traceable standards.
  4. Field Sampling & Laboratory Analysis – Employing isokinetic sampling where required and analysing samples under controlled lab conditions.
  5. QA/QC Controls – Blanks, duplicates, standard reference materials, method validation.
  6. Transparent Reporting – Full documentation, clear presentation of data, comparison with standards, actionable insights.
