Waste heat is extracted in two stages from the exhaust (20) of a biomass dryer (14) in a grain alcohol plant (10). A boiler circuit (56) provides high pressure steam to a balance of the plant (54). A first energy recovery circuit (36) extracts heat from the exhaust via a non-contact heat exchanger (24) and provides a first relatively lower pressure steam (78) to the balance of the plant, thereby bypassing a portion of the boiler circuit. Working fluids in the boiler and first energy recovery circuits are maintained within boiler water quality specifications and are intermixed to allow the production of the first relatively lower pressure steam without a pressure reduction device. A second energy recovery circuit (44) extracts heat from the exhaust downstream of the first energy recovery circuit using a direct contact heat exchanger (38) and provides a non-boiler quality heated fluid (52) to the balance of the plant.

The vortex tube when properly used within a Rankine cycle can produce phenomenal results. This invention functionally describes the preferred vortex tube used to produce superheated vapor from a compressed heated liquid without summoning the additional heat required for latent-heat to effect vaporization. The vortex tube provides superheated vapor to a turbine for generating electricity burning 50% less fossil fuel, also releasing 50% less carbon emissions to the environment. The vortex tube extends the efficient Rankine Cycle temperature range well below 150 F. with the proper refrigerant choice. The physical size and function of the hearing equipment is reduced. The invention delivers new thermal efficiencies for both the Rankine Cycle and the Organic Rankine Cycle.

A system for generating steam for industrial heat. The system may include a plurality of heat pump cycles in thermal communication with each other and in thermal communication with a steam generation cycle. The plurality of heat pump cycles may include first and second heat pump cycles. The first heat pump circulates a first a working fluid and includes a first heat exchanger. The second heat pump cycle circulates a second working fluid and includes a second heat exchanger. The first heat exchanger transfers heat from the first to the second working fluid. The second heat exchanger transfers heat to a third working fluid in the steam generation cycle.
