Abstract: An improved cavitation mixing and heating device employs an inlet directed toward the vertex of a conical or similar flow-directing element. The flow patterns of the fluid material to be mixed and heated are designed to preheat, spread, and create turbulent flow mixing of the fluid before it enters the cavitation zone, using heat generated in the cavitation zone that is conducted through the body of the cavitation rotor. The functions of the axially oriented inlet and flow directing element are assisted by a cantilever construction to alleviate stress on the bearings.

Abstract: A cavitation device is supplied by a disc pump with fluids for mixing. A cavitation rotor, having an array of cavities on its cylindrical surface, is fixed to a shaft for rotation by a motor. The disc pump and the cavitation device are beneficially in the same housing. At least one disc is spaced from and attached to the rotor near the inlet end of the cylindrical housing, so it will rotate with the rotor. A central hole in the (at least one) disc permits fluid to enter the space between the disc and the rotor; it is flung toward the peripheral space between the rotor and the cylindrical housing, where it is subjected to cavitation, and then passed to an outlet. The shaft may pass through one or both of the end walls of the cylindrical housing. The cavitation pump is especially useful for mixing oil field fluids.

Abstract: A solid fuel product can include a carbon based solid fuel, a cementitious material, and a plastic material. The carbon based solid fuel can include coal, petroleum coke, wood and/or other carbon products. The cementitious material can include Portland cement, lime, calcium aluminate cement, natural cement, slag cement, blended cement, cement kiln dust, lime kiln dust, and/or fly ash. The plastic material can include a thermoplastic material and/or a thermoset material. The solid fuel product can include about 45% by weight to about 98% by weight of the carbon based solid fuel and about 1% by weight to about 50% by weight of the plastic material.
