Diesel Generator (DG) sets are commonly used for power backup in factories, hospitals, offices, malls, and residential societies. While DG sets are very useful, they also produce smoke and harmful gases that pollute the air.
To reduce this pollution, an Emission Control Device is used with DG sets. Let’s understand this concept in very simple language.
What Is a DG Set Emission Control Device?
A DG Set Emission Control Device is a special pollution-control unit fitted to the exhaust (smoke outlet) of a diesel generator.
In simple words:
It cleans the smoke coming out of the DG set before it goes into the air.
These devices help DG sets follow pollution rules set by authorities like the Central Pollution Control Board (CPCB).
Why Is an Emission Control Device Needed?
When a DG set runs, it releases:
- Black smoke
- Tiny dust particles (PM)
- Harmful gases like CO and NOx
These can cause:
- Breathing problems
- Eye irritation
- Serious health issues
- Environmental damage
Because of this, pollution authorities have made emission control devices mandatory for many DG sets.
How Does a DG Set Emission Control Device Work?
The working is very simple:
- Smoke enters the device from the DG set exhaust
- Harmful particles and gases are trapped or treated
- Cleaner smoke is released into the air
So instead of dirty smoke, much cleaner exhaust comes out.
Types of DG Set Emission Control Devices
1. Filter-Based Device
- Uses filters to trap black smoke
- Needs regular cleaning
2. Filterless Device
- Uses advanced technology
- Low maintenance
- Longer life
3. Retrofit Emission Control Device (RECD)
- Installed on old or existing DG sets
- Helps meet current pollution norms
- Most commonly used in India
Where Are Emission Control Devices Used?
These devices are used in:
- Factories & industries
- Hospitals
- Malls & offices
- Data centers
- Residential societies
- Construction sites
Anywhere a diesel generator is used, an emission control device helps reduce pollution.
Advantages of DG Set Emission Control Device
Main benefits include:
- Reduces black smoke
- Improves air quality
- Helps follow pollution laws
- Avoids fines and legal action
- Environment-friendly operation
- No need to replace old DG set
Is It Mandatory in India?
Yes. For many existing and old DG sets, installing an emission control device is mandatory.
Running a DG set without it can lead to:
- Heavy fines
- Legal notices
- DG set shutdown
Simple Summary
- DG sets cause air pollution
- Emission control devices clean DG set smoke
- They are required by law in many cases
- They protect health, environment, and your business
A DG Set Emission Control Device is not just a rule—it’s a responsibility.
