Fuels

Ki Energy's technology has the advantage of producing value in the form of heat and power, while getting rid of the burden represented by many waste materials. This is a win-win situation.

Ki Energy's plants are tailor made in order to be adapted to any local situation, starting from the biomass availability and energy-heat requirements.

Ki Energy's plants can be extremely flexible in terms of combustibles:

  • RDF (urban waste)
  • MBM (Meat bone Meal)
  • glycerine
  • tyres
  • urban sludges
  • bituminous sands
  • plastics
  • rice husk and dust
  • vegetables processing refuse parts
  • lignocellulosic biomass
  • olive bagasse
  • mais residuals
  • vine and olive pruning residual
  • poultry droppings
  • sunflower seeds
  • corn grain and silage
  • algae mill residuals

Fuels employed in the fluidized bed combustor or gasifier must be characterized by an humidity percentage lower than 15%. In case of higher values of humidity, biomass will be dried by dedicated dehydrators integrated in the plant.

For this kinds of combustibles and for all of them with an high content of sodium and potassium, Ki Energy patented sands usage which are able to maintain properties reque's sted from bed fluidization avoiding agglomeration.

Ki Energy's piroliser can transform any kind of plastic material from hydrocarbon derivation, tyres, exhausted oils and lignocellulosic biomass.
