METHOD TO PREPARE FUEL OIL FOR BURNING Russian patent published in 2014 - IPC B01F3/08 

FIELD: power engineering.

SUBSTANCE: in the method to prepare fuel oil for burning from the total volume of the main flow of fuel oil they take a volume of side flow of fuel oil equal to 1.5 - 2% of the volume of the main flow of fuel oil. The main flow of fuel oil is sent into the line of the side flow of fuel oil. Heating of the fuel oil flow, mixing of an additive and fuel oil is carried out in the line of the side flow of fuel oil, in parallel connected to the line of the main flow of fuel oil. Mixing of the volume of the side flow of fuel oil and the additive is carried out without participation of movable mechanical facilities by means of a mixer made in the form of a device for static mixing of fuel oil and additive. The additive is supplied into the line of the side flow of fuel oil to the process of static mixing of fuel oil and the additive.

EFFECT: simplified process circuit with preservation of high operational characteristics of fuel oil due to high homogenisation of the introduced additive and fuel oil by means of intensive mixing and automation of preparation of homogeneous mixture of fuel oil and additive, efficient preparation and burning of liquid fuel with release of smaller quantity of toxic substances, increased reliability, cost effectiveness and environmental safety of boiler plants.
