FIELD: power engineering.
SUBSTANCE: system has furnace (12), particle separator (14) connected with the furnace, external preferably uncooled heat exchange chamber (16) connected with the particle separator, returning passage (16) connected with the heat exchange chamber for returning separated particles, rigid bearing structure (52,56) for supporting the members of the system, and suspension device (60,62,64,68) for suspension the heat exchange chamber on the rigid bearing structure. The suspension device has pipes for vapor or water which provide temperature from 300oC to 550oC.
EFFECT: enhanced efficiency.
