MRC Production

DICE requires cost-effective production of ultra-low ash water based slurry fuel called MRC. The earlier USDOE work concluded that coal with 2–3% ash was suitable for DICE. The ash will be a trade-off between processing cost, and maintenance costs. Depending on engine speed, MRC should have a top size of 50 µm, a coal loading of 50-55%, and enable pressure atomisation. Coarser and higher solids MRC will likely be preferred for future engines.

Large slow speed engine for DICE

Engines

It is generally accepted that lower speed diesel engines are most suitable: the low-speed two-stroke marine-type engines (10–100 MW at 90–120 rpm) and largest four-stroke medium-speed engines (20 MW at 400-500 rpm). This is due to their low maintenance, longevity and tolerance to current lower quality fuels.

The choice of engine will be site and application dependent: the low-speed engine has slightly higher efficiency and lower maintenance costs but the cost is $2 M/MW compared to $1.2 M/MW for medium-speed engines.

 

 


More Information

DICE needs considerable development and demonstration to match the technical development of current technologies, but has strong technical merit because of the ability to carry out a near-commercial scale demonstration at a relatively small size (around 10 MW), both quickly and at relatively low cost. A staged development program has been devised with MAN for both black and brown coals, to de-risk the demonstration projects proposed for 2015.
