RECD for DG SetInstalling a is a technical process that requires proper assessment of the generator and exhaust system. Since the device becomes part of the exhaust pathway, its installation should be planned carefully.

A good installation begins before the equipment reaches the site. DG-set specifications, engine compatibility, exhaust characteristics, applicable CPCB requirements, and maintenance needs should all be evaluated.

Why Is RECD Installation Important?

An emission-control device cannot perform as intended if it is incorrectly selected or installed.

The exhaust system has specific flow, temperature, pressure, and space requirements. Adding an unsuitable device can affect the exhaust system and potentially the generator's operation.

CPCB's published RECD procedure links retrofit devices to specific engine families and certification ranges, highlighting the importance of technical applicability.

Step 1: Collect DG-Set Information

The installation process should start with the generator's technical information.

Important details include:

DG-set capacity
Engine manufacturer
Engine model
Engine family
Engine power
Manufacturing details
Fuel type
Exhaust pipe specifications
Operating load

This information is required to determine the appropriate RECD.

Step 2: Check RECD Applicability

The proposed RECD should be checked against the engine and power range.

CPCB publishes a list of certified RECD manufacturers with different applicability ranges.

This information should be checked before purchasing or installing the equipment.

Step 3: Inspect the Exhaust System

The existing exhaust system should be inspected.

Important factors include:

Exhaust-pipe size
Exhaust flow
Exhaust temperature
Available space
Mounting arrangement
Back pressure
Access for maintenance

The RECD should be installed in a position that is technically appropriate and accessible.

Step 4: Prepare the Installation Area

The installation area should provide sufficient space for the equipment and allow technicians to inspect and maintain it.

Because exhaust components can operate at high temperatures, appropriate safety considerations should also be followed.

Step 5: Install the RECD

The device is then integrated into the exhaust system according to the manufacturer's technical instructions.

Connections should be properly secured and the exhaust system should be inspected for leaks or installation problems.

Step 6: Check Generator Operation

After installation, the generator should be operated and monitored.

The technical team should check the exhaust system and generator performance.

Any abnormal noise, excessive smoke, temperature issue, or operational problem should be investigated.

Why Is Back Pressure Important?

Exhaust gases need to leave the engine efficiently.

An emission-control device can create resistance in the exhaust system. Therefore, the resulting back pressure should remain within the engine manufacturer's acceptable limits.

This is one reason why RECD installation should be treated as an engineering task rather than a simple accessory installation.

What About Engine Condition?

Before installation, the DG engine should be checked for major performance problems.

For example, excessive black smoke can be related to:

Poor air supply
Injector problems
Over-fueling
Poor combustion
Fuel-system issues
Engine wear

Such issues should be diagnosed and repaired.

The RECD should complement engine maintenance rather than replace it.

What Maintenance Does an RECD Need?

Maintenance requirements depend on the specific device.

The generator should continue to receive routine servicing.

Important checks include:

Engine oil
Air filter
Fuel filter
Injectors
Cooling system
Exhaust system
Battery
Belts and hoses
RECD condition

The manufacturer's recommended inspection schedule should be followed.

Why Should Records Be Maintained?

Organizations should maintain records related to the DG set and RECD.

Useful records include:

DG specifications
RECD model
Installation date
Certification information
Maintenance history
Inspection details
Testing information where applicable

Good records help with future maintenance and compliance-related reviews.

Frequently Asked Questions

Can RECD be installed on an old DG set?

A suitable existing DG engine may be eligible for retrofitment, subject to technical and regulatory applicability.

How long does installation take?

Installation time depends on the generator's exhaust arrangement, device type, site conditions, and required modifications.

Can anyone install an RECD?

Technical installation should be performed by qualified personnel familiar with the device and DG exhaust system.

Is maintenance required after installation?

Yes. Both the DG set and RECD require appropriate maintenance.

Conclusion

RECD installation involves much more than attaching equipment to an exhaust pipe. Correct engine identification, certification applicability, exhaust assessment, installation, operational checks, maintenance, and documentation are all important.

Organizations should review the current CPCB information and the RECD manufacturer's technical documentation before proceeding with installation.
