PULSATING COMBUSTION HEAT GENERATOR Russian patent published in 2002 - IPC

FIELD: combustion of fuel in pulsating flow. SUBSTANCE: pulsating combustion heat generator has ejector, pulsating combustion chamber with aerodynamic valve including combustion chamber with fuel feed and igniting system and resonance tube arranged in common housing telescopically connected with ejector for axial displacement, and pair pipe with inlet and outlet sections. Heat generator has cooling and mixing chamber connected with ejector whose axis is arranged square to ejector axis. Cooling and mixing chamber has cylindrical section with branch pipe for delivery of gases from ejector over chamber circumference, conical section terminating in outlet nozzle, convergent air nozzle arranged inside said chamber, and branch pipe for connecting outlet section of air pipe. Outlet section of air pipe is telescopically connected with inlet section of air pipe with gate installed inside. Inlet section of pipe is provided with bell arranged coaxially with end of aerodynamic valve projecting from housing. EFFECT: enlarged operating capabilities owing to increased range of working mixture temperature regulation provided by mixing of hot and cold air directly before treatment of products or before delivery into air heating system. 2 dwg
