Abstract
Combustible compositions in the form of homogeneous water-in-oil and/or organic emulsions, deriving from heterogeneous fatty waste and containing solid particles in suspension are prepared by carrying out a dynamic homogenisation operation and an emulsification operation in the presence of an emulsifying agent and/or a base such as an alkali or alkaline-earth metal hydroxide. These combustible compositions can be used for combustion in a variety of furnace types.
Claims29
A combustible substantially homogeneous composition comprising solid particles suspended in a stable water-in-oil emulsion comprising an oil phase, a water phase and emulsifier, said solid particles and said oil phase being derived substantially from dynamically homogenized heterogeneous organic agro-food industry fatty waste products.
A combustible substantially homogenous composition comprising solid particles suspended in a stable water-in-oil emulsion comprising a fatty oil phase, a water phase and an emulsifier, said fatty oil phase and said solid particles consisting essentially of dynamically homogenized organic agro-food industry waste products.
A process for producing a combustible composition comprising suspended solids in a stable water-in-oil emulsion formed from heterogeneous fatty waste, said process comprising conducting a granulometric homogenization of said fatty waste, and implementing emulsion formation by adding to the fatty waste during or after homogenization at least one base selected from the group consisting of alkali metal hydroxides and alkaline earth metal hydroxides.
A combustible composition comprising suspended solids in a stable water-in-oil emulsion formed from comminuting heterogeneous solid waste, said emulsion further comprising in the oil phase at least one agent blocking fermentation.
