Diesel generator (DG) sets are extensively used to provide power backup to industries. Yet, they also contribute to air pollution. Due to increasing environmental concerns and strict emission regulations, companies are now implementing Retrofit emission control devices (RECD) to DG sets to lower harmful emissions. These sophisticated devices provide an environmentally sustainable solution to reduce emissions while ensuring compliance with standards set by the government. In this article, we will look at the advantages, capabilities, and importance of RECD in DG Set to achieve better air quality.
What is RECD for DG Set?
The retrofit emission control device (RECD) is an advanced filtration system that is designed to reduce particles of matter (PM) and NOx, nitrogen oxides (NOx) and other harmful emissions emitted by diesel generators. The devices function by neutralizing and capturing pollutants before their release into the air. RECD in DG Set helps decrease air pollution, increases the efficiency of fuel, and ensures that regulatory compliance is maintained.
Importance of RECD for Diesel Generators
- Conformity with Government Regulations
- The Indian government, in the Central Pollution Control Board (CPCB), has made it compulsory for companies to install RECDs for DG sets to reduce emissions.
- Failure to comply could result in sanctions as well as operational restrictions.
- Reduction in Harmful Emissions
- RECD significantly reduces the emission of NOx PM along with carbon monoxide (CO) and improves the quality of air.
- This is particularly important, especially in industrial and urban zones where pollution levels are high.
- Improved Public Health
- Diesel emissions are a source of fine particles that can cause respiratory illnesses, lung infections, and heart problems.
- Installing RECD in the DG Set helps in making these risks less harmful to health.
- Enhanced Fuel Efficiency
- Certain RECD models enhance the combustion of fuel and improve energy efficiency.
- This means cost savings for companies that use DG sets regularly.
- Sustainability and Corporate Responsibility
- Companies who make investments in RECD show their commitment to protecting the environment.
- It boosts brand image and is aligned with corporate sustainability objectives.
How Does RECD for DG Set Work?
RECD is a DG Set that functions using advanced catalytic and filtration processes to capture and break down harmful emissions. The process involves:
- Particulate Matter Filtration
- RECD utilizes high-efficiency filters to remove fine particles from diesel exhaust.
- Catalytic Conversion
- A catalyst assists in the breakdown of harmful gases such as NOx and CO, transforming them into safer compounds like carbon dioxide and nitrogen.
- Regeneration Process
- Certain RECD models can automatically regenerate and cleanse the filters, which ensures continuous effectiveness.
- Monitoring and Control
- Advanced RECD systems include sensors and IoT connectivity for continuous monitoring and analysis of emission levels.
Types of Retrofit Emission Control Devices for DG Sets
Different kinds of RECDs used in DG sets exist based on filtering and emission control techniques. The most commonly used types include:
- Diesel Particulate Filters (DPF)
- Reduces the amount of particulate matter in the air and emissions efficiently.
- Ideal for industries that have high DG usage. It is ideal for companies with a high volume of DG.
- Selective Catalytic Reduction (SCR) Systems
- Converts NOx emissions into water and nitrogen through a catalyst chemical.
- Commonly used in large-scale industrial operations.
- Diesel Oxidation Catalysts (DOCs)
- Reduces carbon monoxide as well as hydrocarbon emissions.
- It is cost-effective and widely accepted.
Factors to Consider When Choosing RECD for DG Set
If you’re looking to install RECD to DG Set, take into consideration these factors:
- DG Set Capacity
- Check that you are using a RECD system that is in line with the generator’s capacity to maximize performance.
- Compliant to CPCB Norms
- Select an approved by the government RECD model that is compliant with the most recent emission standards.
- Maintenance and Durability
- Select an easy-to-maintain RECD that has a long life to maximize your savings.
- Installation and Integration
- Verify if the RECD can be easily included in your current DG configuration.
Government Initiatives and Support for RECD Adoption
The Indian government has been actively encouraging RECD to DG Set via different initiatives.
- Subsidies and Incentives: Some states offer financial assistance to RECD installations.
- Strict Regulators: CPCB has enforced the emission standards for mandatory DG sets with capacities above certain levels.
- Information Campaigns The goal is to promote sustainable DG use to help industries take advantage of RECD technology.
Conclusion
With the rising levels of pollution and tighter regulations, retrofitting emission control devices (RECD) to DG Set is now an essential requirement for companies who rely upon diesel engines. They not only aid in achieving emission standards but also help ensure healthier air quality and improved public health. If you’re planning to set up an RECD in your DG Set and DG Set, make sure to ensure compliance with CPCB guidelines and select the best system for the needs of your business. In implementing RECD, the industry can leap sustainability while still utilizing effective power backup systems.
