METHOD FOR PRODUCING COMPOSITE FUEL Russian patent published in 2024 - IPC B05B17/04 F23K1/02 F23K5/12 C10L1/32 

FIELD: fuel suspensions.

SUBSTANCE: invention relates to methods for mixing solid fuel with liquid and can be used for preparing fuel suspensions and injecting them into the combustion chamber. A method for producing composite fuel is disclosed. Separately crushed coal with a particle size of 0.1–0.6 mm, water and waste transformer oil are simultaneously sprayed into the combustion chamber of the boiler. In this case, the opening angle of the nozzle of the device for supplying coal particles, the full-cone nozzle for spraying water and the pneumatic nozzle for spraying waste transformer oil is 60°, and the angle between the spray axes of the components is 10°. Crushed coal is sprayed under a pressure of 0.22 MPa, water is sprayed under a pressure of 0.2 MPa, waste transformer oil is sprayed under a pressure of 0.3 MPa. The following ratio of components is also observed, wt.%: crushed coal – 75; water – 5; waste transformer oil – 20.

EFFECT: production of composite fuel.
