Intercem3 
At the Intercem Energy Forum in Cairo we presented N+P’s vision on 
alternative fuel usage from traditional SRF to the new Subcoal®.
Thank you if you attended our presentation at Intercem, below you
will find a summary of the presentation.

N+P Group

N+P Group has been a major provider of alternative fuels to the cement , lime and power industries for more than 20 years. The whole N+P group moves +/- 2 million tons of industrial waste.

Refuse derived Fuels

Refuse derived fuel (RDF) is produced from commercial industrial sources and municipal sources. RDF has CV less than 15MJ/kg.

RDF typical specification

Netto calorific value (as received) >13.000 Kj/kg
Net calorific value (dry matter) >16.000 Kj/kg
Ash content <15 W.-%
Moisture <30 W.-% DW
Chlorine <1,0 W.-% DW
   
Typical physical size < 500 mm

Solid Recovered Fuels

Solid recovered fuel (SRF) is typically used to replace fossil fuels. It is a non hazardous material and has CV greater than 15MJ/kg. SRF is produced to the specification of our customers.

SRF (calciner quality) typical specification  
Netto calorific value (as received)    >16.000 kJ/kg             
Ash content <15 W.-%
Moisture <15 W.-% DW
Chlorine <0,8 W.-% DW
Typical physical size <30 mm
   
SRF (main burner) typical specification  
Netto calorific value (as received) >20.000 Kj/kg   
Ash content <14 W.-%
Moisture <15 W.-% DW
Chlorine  <0,8 W.-% DW 
Typical physical size < 30 mm

Subcoal®

Subcoal® is a new type of fuel, produced via a proprietary technology owned by N+P. The unique feature of Subcoal® is that it is a very stable and high quality alternative fuel, which can be treated in the same way as bituminous coal is typically treated. The Subcoal® pellets are typically ground before being used in a kiln or boiler, and can even be co-grinded together with bituminous coal in a vertical roller mill or ball mill. Ground Subcoal® has a very short burnout time, comparable to lignite or coal dust. These features make Subcoal® an excellent fuel for new markets which are just starting to substitute fossil fuels, or existing markets looking to achieve the final percentages of substitution.

Subcoal® pellets typical specification

Netto calorific value (as received)          >20.000 kJ/kg                              
Ash content <12 W.-%
Moisture <8 W.-% DW
Chlorine <0,8 W.-% DW
Typical physical size (not grinded) Ø 8 mm (length < 3 cm)
   
Typical physical size (grinded) < 5mm

Subcoal® shows hydrophobic behaviour, the pellets do not dissolve in water and have been stored outside at several installations.
