How Is a DG Set RECD Device Installed in an Existing Generator?

Installing a DG Set RECD Device involves integrating an emission-control unit into the exhaust system of an existing diesel generator. The installation needs to account for exhaust flow, temperature, back pressure, physical space, and engine specifications. Proper installation is important for both emission-control performance and reliable DG operation.

What Happens During RECD Installation?

The RECD is generally positioned in the DG set's exhaust arrangement so that exhaust gases pass through the device before being discharged.

The exact installation method depends on the DG set and RECD design.

What Are the Main Installation Steps?

1. Collect DG Set Details

Before installation, gather:

• DG capacity

• Engine make and model

• Exhaust dimensions

• Exhaust flow

• Exhaust temperature

• Operating load

• Back-pressure limits

2. Inspect the Existing Exhaust System

The existing exhaust piping should be checked for condition, size, leakage, and available installation space.

3. Position the RECD

The device should be positioned according to the manufacturer's installation instructions.

Adequate space should also be provided for inspection and maintenance.

4. Connect the Exhaust Piping

The RECD is connected to the exhaust system using suitable connections and supports.

5. Check Back Pressure

After installation, exhaust back pressure should be checked to ensure it remains within the permissible limit.

6. Inspect for Leakage

All connections should be checked for exhaust leakage before normal operation.

7. Commission the System

The system should be commissioned according to the manufacturer's instructions and applicable requirements.

Why Is Professional Installation Important?

Incorrect installation can create problems such as:

• Excessive exhaust restriction

• Exhaust leakage

• Poor mechanical support

• Increased maintenance requirements

• Potential impact on engine operation

Professional installation can help avoid these issues.

What Should Be Done After Installation?

The DG set should be monitored during operation.

Operators can review relevant parameters such as:

• Back pressure

• Exhaust temperature

• DG performance

• Visible smoke

• Unusual noise or vibration

Conclusion

Installing a DG Set RECD Device requires proper planning and technical evaluation. The existing exhaust system, engine specifications, exhaust flow, temperature, and back-pressure limits should be considered before installation. Correct installation and commissioning help ensure that the RECD performs as intended while remaining compatible with the DG set.

FAQs

1. Can an RECD be installed on an existing generator?

Yes, if the DG set is technically compatible with the selected retrofit device.

2. What should be checked before installation?

DG specifications, exhaust flow, temperature, pipe dimensions, back pressure, and available space should be checked.

3. Why is back-pressure checking necessary?

It helps confirm that the additional exhaust device is not creating excessive resistance.

4. Should the RECD be supported mechanically?

Yes. Proper mounting and support are important for safe and reliable operation.

5. Can I install an RECD myself?

Professional installation is generally advisable because the device becomes part of the DG exhaust system.
