REGENERATIVE HEATER Russian patent published in 1994 - IPC

FIELD: heat power engineering. SUBSTANCE: heater housing i is divided by horizontal partition 2 into upper and lower compartments. Heating compartment accommodates perforated overflow disks arranged in tiers with perforated toroidal header 11 placed under lower disk above partition 2. Inner diameter of header 11 is greater than diameter of lower disk 10. Perforation is made in header 11 on inner side surface of torus with the result that steam flow out of holes in jets above and below header and does not reach walls of housing 1. When power unit is started, steam goes via pipe connection 6 to turbine flow path. EFFECT: improved design. 2 dwg
