Understanding the 50 mg/Nm³ Emission Norm
As per CAQM Direction No. 98, industries across Delhi NCR must comply with a maximum particulate matter (PM) emission limit of 50 mg/Nm³.
Key regulatory requirements:
- Mandatory installation of Air Pollution Control Devices (APCDs)
- Applicable to boilers, thermic fluid heaters, and industrial furnaces
- Target industries include Red Category (Medium & Large) units
- Compliance deadlines:
- Medium & Large Industries: July 2026
- Remaining Industries: September 2026
Industrial units unable to meet the revised emission norms may face operational restrictions or penalties.
Industries Covered Under the Directive
As per CAQM Direction No. 98, the revised emission norms apply to specific categories of industries operating boilers and furnaces generating particulate emissions.
The following industry segments are required to comply:
Red Category (Medium & Large) Industries
Industries classified under the CPCB Red Category with significant particulate emissions from industrial operations, particularly those involving solid fuel combustion and dust-generating processes.
Food & Food Processing Units with Boilers
Units operating coal or biomass-fired boilers for steam generation, where flue gas emissions require effective particulate control.
Textile Industries with Boilers / Thermic Fluid Heaters
Textile processing units using boilers or thermic fluid heaters, especially where solid fuels are used and particulate emissions are generated.
Metal Industries Operating Furnaces
Industries using industrial furnaces for heating, melting, or processing metals, where dust and particulate emissions are generated during operation.
Immediate action is required if your plant:
- Operates solid fuel-based boilers or furnaces
- Has visible stack emissions or high particulate discharge
- Is unable to meet the 50 mg/Nm³ emission standard
- Has received or is expecting a pollution control notice from authorities
Key Consideration:
If your process involves combustion or material handling generating particulate matter, installation of a properly engineered APCD system is essential to achieve compliance.
Recommended APCD Solutions for 50 mg/Nm³ Compliance
To achieve the mandated 50 mg/Nm³ particulate emission standard, industries are required to install properly engineered Air Pollution Control Devices (APCDs) based on process conditions, fuel type, and dust characteristics.
TECHFLOW provides engineered APCD solutions for boiler and furnace emission control, including:
Bag Filter Systems (Baghouse)
Designed for high-efficiency particulate removal in:
- Boiler flue gas filtration (coal / biomass-fired systems)
- Furnace dust collection
- High dust load industrial processes
Key capabilities:
- High collection efficiency for fine particulate matter
- Consistent performance under variable load conditions
- Suitable for continuous industrial operation
Electrostatic Precipitators (ESP)
Applicable for large gas volumes and specific process requirements in:
- Boiler emission control systems
- High-temperature flue gas applications
- Continuous base-load operations
Key capabilities:
- Efficient handling of large gas flow rates up to 2,00,000 m3/hr
- Low pressure drop operation
- Proven performance in process industries
Application-Based System Selection
Selection of APCD is based on:
- Process type (boiler / furnace)
- Dust load and particle characteristics
- Flue gas temperature and composition
Replace Inefficient Systems with Engineered APCD Solutions
Many existing systems are not capable of meeting revised norms.
Instead of temporary fixes, compliance requires:
- Installation of new-generation Bag Filter systems
- Replacement of outdated or undersized dust collectors
- Proper system design based on process conditions
Benefits of replacement approach:
- Assured compliance with 50 mg/Nm³ norms
- Improved operational reliability
- Optimized airflow and pressure drop
- Long-term performance stability
