ABSTRACT:
A reversible aero-hydraulic generator capable of operating as a turbo-pump or as a motor-compressor, and a heat energy recovery installation including such a generator.
The generator comprises a positive displacement pump (5) and an axial turbine (6) tandem connected and coupled by their respective shafts (23 and 11) so that one can drive the other directly and disposed within a single sleeve (1) having end connecting flanges (3 and 4), whereby the sleeve can be directly inserted within a conduit for a first fluid, in the gaseous or vapor phase state, so that the first fluid can pass axially through the sleeve (1), and inlet and outlet conduits (31 and 32) for a second fluid in the liquid or vapor phase, for the pump (5), the conduits (31, 32) passing through the sleeve (1). A heat recovery installation can comprise such a generator for the recovery of heat energy from a drier for printing ink with the pump output used to drive a hydraulic motor to assist in driving the rollers of a printing press.
