FIELD: combustion of suspension of liquid fuel and fuel solids in the form of particles, for example, particles of carbon. SUBSTANCE: the device has a reservoir, burner and pipe-line for conveyance of suspension, whose one end is connected to the burner, and its other end runs to the reservoir and is connected to a pump located in it; a peripheral pump is used as pump, it has an outlet with taps, one of which is connected to the pipe-line for conveyance of suspension, and the other tap or taps is made in the form of a nozzle or atomizer with an outlet directed to the reservoir for agitation of suspension in the reservoir. EFFECT: reduced wear of pump and prevented clogging of its inlet at cooling of particles on the reservoir bottom. 2 dwg
