Slurry Fuels

Basics

• This is a category of fuels that use Slurrys
• The main historical/industrial example is coal slurry/coal-water fuel
  • This has varying composition, and some have additives
• Mainly it consists of a combustible powder in a liquid (for coal slurry it was water and possible additives)
• Can supposedly be used in ICE's and Turbine Engines (Need to see if this impacts emmisions (more soot etc) or maitnence (abrasion etc)
  • Supposedly easier in modified liquid burners like waste oil burners etc, but this may be less efficient?
• Also may require a sort of pilot flame/other burner to "get it going" due to the water making it less flammible

8This also makes it quite stable when stored which could be useful for saftey etc

• RESEARCH NEEDED:
  • Can Charcoal Powder work?
  • Can liquids other than water be used
  • Does the water undergo the Water-Gas Shift Reaction ?
  • if not can the engine/fuel be modified to do so
  • Can it be used in gassifiers?
  • Storage?
