Pulverized Alternative Fuels (PAF)

alternative fuel
for the cement industry

Waste derived fuels are becoming the norm in the cement industry. Fossil fuels become the "alternative" fuel as many kilns are able to substitute over 50% of their fossil fuels.

Trusted for over three decades

N+P were one of the first to produce and supply waste derived alternative fuels to the cement industry. Since our founding in 1992 we have continuously developed our fuel portfolio and we are proud of our position as market leader and pioneer for the industry. We are bringing new and innovative concepts but also continue to supply various grades of RDF and SRF to the markets.

PAF can help a cement plant increase its alternative fuel substitution up to 100%, using existing (coal) feed and burner systems

PAF offers, advantages to a wide range of industrial users

With PAF we believe 100% fossil fuels can be replaced by a waste derived alternative. PAF can be used in a variety of feed systems, including existing PF feeding systems for fossil fuels.

Advanced alternative fuels such as Subcoal® and PAF can offer advantages to a wide range of industrial users, including cement plants that seek to mitigate the rapidly-rising costs of emitting CO2.

PAF can be handled, transported and processed easily.  PAF is used to substitute the initial 10% of substitution, or the final 25% of fossil fuels with minimal alterations to the plant. In many cases PAF can be dosed in using fossil fuel dosing equipment, or under utilized systems like MBM silo's. 

PAF can be supplied as a milled fuel, using variety of modalities like silo (tanker) trucks or walking floor trailers. Alternative is that clients mill the pellets on site themselves.

PAF-burner

PAF has been successfully used to achieve a 100% waste derived flame at a 25 MWt burner at 3.7 tph, achieve a stable flame with a good emissions profile

"We bridge the challenge of a heterogeneous waste material to a high quality alternative for existing processes."

Together we maximize substitution rates

Learn more about N+P's product portfolio, as we know that for each individual site certain challenges will arise. Either from the chemistry in the kiln cycle, or the feeding systems (or lack of feeding systems) which are available. We also offer pulverized fuel solutions which can even be used in existing feed and burner systems.

Why PAF?

When N+P launched Subcoal®, many potential clients asked ‘Why should I use pellets when SRF works perfectly well?’ This is a question that can be expected again when discussing PAF. N+P understands this point. Indeed, Subcoal and PAF should be used in situations where it is not possible, for whatever reason, to use SRF beyond a certain thermal substitution rate. They need not replace other alternative fuels, but rather they bridge the gap between high and very high levels of substitution. For example, PAF could help a cement plant increase its alternative fuel substitution rate from 80% to 100%.
