PROCESS FOR THE MIXING OF LIQUID FUEL WITH WATER, AND APPARATUS FOR THE MIXING, AND THE FUEL-WATER EMULSION

摘要

Method for mixing liquid fuel with water to obtain a combustible emulsion, in which the amount of water to fuel falls in a range of 5 to 35 Vol%, in which the fuel and the water are fed in a closed space in a ratio falling in the range and are intensively moved and recirculated in a closed loop, wherein a reaction space (10, 45) is provided in which the streaming fluid is forced to rotate around and moved along axis (9, 46) of rotation of the space (10, 45) which latter has a tapering cross-section in flow direction so that the pressure continuously decreases both along the axis and in radial direction towards the axis, the fluid which is rotating around the axis (9,46) when leaving the space is caused to rotate around a second axis (17, 54) closing an angle with the first axis (9, 46) which causes gradual braking down and cessation of the first rotation movement, and a portion of the recirculated fluid is lead out of the loop in such a stream that in average the fluid particles participate at least in ten full cycles before they would leave the loop. A fuel-water emulsion is provided that comprises water in 5 to 35 Vol% made by mechanical mixture of a starting fuel and water, in which the structure of fuel component in the emulsion differs from that of starting fuel and has a higher calorimetric value than the starting fuel has.
