METHOD OF PREPARATION OF WATER-AND-FUEL EMULSION AND DEVICE FOR REALIZATION OF THIS METHOD Russian patent published in 2007 - IPC F02M25/25 F02B47/02 B01F3/08 

FIELD: manufacture of engines; methods and devices for preparation of water-and-fuel emulsions.

SUBSTANCE: proposed method includes mixing of definite metered amount of water with fuel and keeping of mixture in continuous motion during definite period of time followed by feeding the emulsion to fuel injector of power plant. Unexpended portion of emulsion after previous emulsification cycle is not mixed with new portion of emulsion whose concentration differs from previous one. Water-and-fuel emulsion is prepared separately for each mode of operation of power plant in separate stabilizers-accumulators. Emulsion is fed to power plant till complete consumption. Empty stabilizer-accumulator is filled at new concentration of water corresponding to present state of power plant which is supplied during this period of time from another stabilizer-accumulator. Volume of water-and-fuel emulsion is so selected that time of its consumption from one stabilizer-accumulator is sufficient for homogenization of water-and-fuel emulsion in another stabilizer-accumulator which is achieved due to repeated rotation and emulsification in closed loop. Device proposed for preparation of water-and-fuel emulsion includes emulsifier and controllable metering and change-over units. Introduced additionally between emulsifier and fuel injectors of power plant are stabilizers-accumulators connected with water and fuel supply passages at inlet and with emulsifier at outlet; water-and-fuel emulsion is fed from them to power plant for combustion. Volumes "V" of stabilizers-accumulators are determined depending on filling time "t" required for homogenization of water-and-fuel emulsion at preset flow water "F" by the following formula V=tF. Stabilizers-accumulators are made in form of reservoirs connected to fuel loops; swirlers mounted at their inlets are used for rotation and acceleration of homogenization of water-and-fuel mixture.

EFFECT: enhanced operational reliability of power plant.
