Diesel Particulate Filter Kilns Information

Utilizing a diesel particulate filter thermal cleaning kiln, and heating the filter through this process, ensures that the diesel particulate filters are properly and thoroughly cleaned, allowing them to function properly. 

If the DPF is not heated, some debris may remain in the filter increasing the cleaning interval, costing the diesel operator more money in the long run.

Here's a Sample DPF Firing schedule:

Note: The specific firing schedule may vary depending on the DPF manufacturer, its filters condition, and the desired level of cleaning. Always consult the DPF manufacturer's guidelines for the most accurate and safe procedures. This is a general guide, not a "how-to" tutorial, please do your own research and speak to others in your industry to learn the best practices.

Here's a general firing schedule using multiple segments in Fahrenheit:

Segment 1: Pre-Heat
* Temperature Range: 150°F to 350°F
* Duration: 10-15 minutes
* Purpose: Gradually warms up the DPF to prevent thermal shock.

Segment 2: Soot Oxidation
* Temperature Range: 350°F to 800°F
* Duration: 30-60 minutes
* Purpose: Oxidizes soot particles in the DPF.

Segment 3: High Temperature Cleaning
* Temperature Range: 800°F to 1000°F
* Duration: 30-60 minutes
* Purpose: Removes any remaining soot and ash.

Segment 4: Cool Down
* Temperature Range: 1000°F to 150°F
* Duration: 30-60 minutes
* Purpose: Gradually cools down the DPF to prevent thermal shock.

Additional Considerations:
* Oxygen Supply: Ensure adequate oxygen supply during the cleaning process.
* Monitoring: Monitor the DPF's temperature and pressure throughout the cleaning cycle.
* Repeat Cycles: If necessary, repeat the cleaning process until the desired level of soot removal is achieved.
* Professional Assistance: For complex or heavily clogged DPFs, consider consulting a professional for cleaning.

Remember: This is a general schedule. Always refer to the DPF manufacturer's specific guidelines for the most accurate and safe cleaning procedures.

For those who need a specific DPF Firing schedule to enter based on the above guidelines:
Segment 1: 250F p/h to 350F - HOLD 15min
Segment 2: 350F p/h to 800F - HOLD 60 min
Segment 3: 350F p/h to 1000F - HOLD 60 min
Segment 4: off
Do not open the oven door until you are under 200F.
