FIELD: power engineering.
SUBSTANCE: nozzle for spraying of water-coal fuel comprises a hollow cylindrical body with a jet device and a fuel swirler and a radiator representing hollow bodies of revolution with flat ends installed inside the body with an annular gap. In the fuel swirler at the end facing the jet device, there is an annular ledge along the inner diameter, and in the radiator at the end facing the jet device there is also a circular ledge along the inner diameter, and the front part of the jet device is made in the form of a truncated cone.
EFFECT: invention provides for high extent of fuel preparation in the inner cavity of a nozzle due to increased time of fuel stay in the area of its reaction with a sprayer, intense grinding of fuel drops with supersonic sprayer jets, which are flowing from channels.
