Power Generation: Sustainability

[evany]

I am intereted in learning about genset user preferences for diesel particlute filters to reduce PM emissions-for both stand-by and prime power usage.   There are several passive and active technologies available.  Typically, field retrofit requires professional contracting services for integration, access to metal fabrication resources and lift equipment for installation.  I am hoping to gain some insightful comments and "real world" experiences.

Cleaire makes a good PM trap for engines up to the 400hp range or so. It is designed for stationary use. The model is called the Horizon S. We are in the process of the installation, utilizing a mechanical contractor for the physical installation. It appears to be very straightforward and boasts a 99%+ reduction. This unit is also available in on-highway applications. At $30k+ for the unit including installation, you should have a strong desire to reduce PM. See www.cleaire.com

Correction...85% reduction.

Evany,

You can research passive and active diesel particulate systems on the CARB website at http://www.arb.ca.gov/diesel/verdev/vt/cvt.htm. All Level 3 verified products must reduce PM greater than 85%. There are many differences between passive and the newer active system technologies, such as cost, complexity, ease-of-use, and ease of installation. There are also differences in quality such as products made of stainless steel vs. mild steel.

For a product that offers optimal performance for a specific application, look into companies with custom design and fabrication services. In this way, you work with a design engineer to create a system that fits your customer's space requirements, installation needs, inlet/outlet location and mounting requirements. If a system is designed specifically to fit an application, installation will be much easier, therefore lowering your cost of installation.

CleanAIR Systems' diesel particulate filter is CARB verified Level 3 for prime and emergency engines. http://www.cleanairsys.com/products/filters/index.htm
