One of the promising directions for the development of energy in the 21st century is thermonuclear energy. To implement this method of generating energy, experimental thermonuclear reactors have been operating for decades, the largest of which is currently being built in Cadarache (France). At the moment, one of the unsolved problems of such reactors is the creation of systems that provide reliable heat removal of heat fluxes from intracameral objects, such as a limiter, blanket, and divertor. In addition to high energy density, these objects have quite significant dimensions. Today, cooling of such objects is carried out mainly by water under pressure. This paper considers the possibility of using a dispersed two-component coolant flow as an alternative method of cooling such objects. A description is given of an experimental bench simulating uniform heating along the perimeter of the test section and it's main systems. The paper presents the design of a spray device for forming a two-component dispersed coolant flow with its technical characteristics and a working area for conducting research. Experimental data were obtained on the temperature of the wall of the working area at various operating parameters of the coolant and power input.
