COMBUSTION METHOD FOR LIQUID ORGANIC RADIOACTIVE WASTE, AND PLANT FOR ITS IMPLEMENTATION Russian patent published in 2015 - IPC G21F9/00 

FIELD: machine building.

SUBSTANCE: spraying of waste by an air-stream atomiser and its burning in a cyclone furnace are provided. The cyclone furnace is heated by the heat from the combustion of gaseous or liquid fuel, liquid organic radioactive waste is supplied for combustion continuously, prior to the supply to the air-stream atomiser for spraying, the waste is heated, the air-stream atomiser is cooled by water, the waste is burnt in the presence of fine catalyst particles, secondary air is fed tangentially, cooling and purification of gases are carried out in a bubble column of a jet scrubber first and then in an absorber-condenser. Fuel combustion to heat the cyclone furnace is performed in fluidised bed of catalyst, liquid organic radioactive waste is heated by cooling water of the air-stream atomiser. The plant for liquid organic radioactive waste combustion comprises a cyclone furnace (1) with an air-stream atomiser, a jet scrubber (2), an absorber-condenser (3), water pumps (4/2 and 4/3), a catalytic reactor (7) with fluidised bed of catalyst is used as a starter. The cyclone furnace is mounted on the tank of the jet scrubber, the air-stream atomiser for the supply of liquid organic radioactive waste is located in the upper part of the cyclone furnace.

EFFECT: increased efficiency and environmental safety of liquid organic radioactive waste combustion.
