FIELD: thermal and nuclear power engineering; miscellaneous heat-generating plants. SUBSTANCE: apparatus has fuel elements 1,2 arranged concentrically to form circular slit to receive swirling devices 4 mounted so that they form gap along channel path separated by means of longitudinal ribs provided on convex surface of element 2 into several longitudinal slits. Spiral channels formed by concave surface of external fuel element 1 and changeable parts of swirling device 4 accommodate at least one guide member 7 in the form of annular fragment whose ends abut against turns of swirling device 4. Members 7 are relatively displaced both through width and length of channel confined within turns of device 4. Height of annular fragments at sections between longitudinal ribs does not exceed that of turns of device 4. Guide members 7 are beveled in transverse direction on inlet side of circular channel. EFFECT: improved design. 6 cl, 3 dwg
