📘 Calculation Methodology & HAT Cycle Standards
Direct-Contact Packed Saturator
The countercurrent saturator evaporates hot water directly into compressed air across a temperature glide, recovering low-grade heat down to near-ambient temperatures.
Superior High Specific Power
The massive influx of evaporated water vapor ($15 - 30\%$) superheats in the recuperator, yielding specific power outputs up to $80\%$ higher than standard Brayton gas turbines.
Key Engineering Assumptions
- Intercooled multi-stage centrifugal/axial compression.
- Countercurrent packed saturator with high mass-transfer packing.
- Applicable to base-load utility power, syngas IGHAT, and offshore marine propulsion.
