UTILISER OF WASTE GASES HEAT Russian patent published in 2008 - IPC F23L15/04 

FIELD: technological processes; heating.

SUBSTANCE: utiliser of waste gases heat contains thermal pipes that are made with annular cross sections and through central channels, which are connected with gas supply nozzle, at that condensation sections of pipes are installed in air duct, and evaporating sections - in flue duct, multicyclone. Outlets of central channels of thermal pipes communicate with flue duct bottom part, with which multicyclone element inlets also communicate, which are equipped with vortex generators, and their outlets are connected to nozzles, which are installed in flue duct between thermal pipes, perforated partition that overlaps intertubular space sides with nozzle top ends, and its openings are coaxial to openings of nozzles, at that partition is installed in plane that is inclined at an angle to horizon to provide direction of flows of gas from nozzles purified in cyclone elements in direction to outlet nozzle of flue duct with approximately identical velocities.

EFFECT: efficient purification of gases from hard aerosol particles.
