WATER OR AIR HEATER Russian patent published in 2010 - IPC F24H1/00 F24H3/00 

FIELD: heating.

SUBSTANCE: water or air heater includes volute-shaped header, guide vanes, loading device, axial branch pipes, end walls of hyperbolic shape, rotary scattering unit of solid or liquid fuel or crushed domestic waste, and casing and vortex heat exchanger installed on outer side of vortex combustion chamber, one of the walls of which are walls of vortex combustion chamber. On inner surface of end walls there are micro channels made in the form of three-stage catalytic pack including the layer of high-active Pd-Ge-Al₂O₃ catalyst at the inlet of vortex combustion chamber, the main thermoresistant catalyst on the basis of Mn hexaaluminate and thin layer of Pd-Mn-La-Al₂O₃ catalyst at the outlet of vortex combustion chamber. Inside casing and vortex heat exchanger there are micro channels.

EFFECT: developed heat exchange surface, intensification of heat transfer and reduction of heater dimensions.
