“…Assuming a thermal to electric conversion efficiency of 25%, the total cost of the chemical components, boiler, and steam turbine generator is estimated at $1380 per kWe electric. The system applications for distributed power (1–10 MW electric) and central generation retrofit and green‐field projects are projected to be very competitive relative to existing power sources and systems 10–14.…”

SUMMARY The design and cost estimates compared with other systems of an energy‐producing reactor system are presented. Heat from hydrino reactions within individual cells provides both the reactor power and the heat for regeneration of the reactants. These processes occur continuously over a plurality of cells in different phases of the processes. The hydrino reactions are maintained and regenerated in a batch mode using thermally coupled multi‐cells arranged in bundles wherein cells in the power‐production phase of the cycle heat cells in the regeneration phase. In this intermittent cell power design, the thermal power is statistically constant as the cell number becomes large, or the cell cycle is controlled to achieve steady power. The conversion of thermal power to electrical power requires the use of a heat engine exploiting a cycle such as a Rankine, Brayton, Stirling, or steam‐engine cycle (Int. J. Energy Res. 1997; 21:113–127; Int. J. Energy Res. 1998; 22:237–248; Int. J. Energy Res. 1998; 22:991–1000; Int. J. Energy Res. 2010; 34:1071–1087; Int. J. Energy Res. 2009; 33:1203–1232). Owing to the temperatures, economy goal, and efficiency, the Rankine cycle is the most practical and can produce electricity from a steam source at 30–40% efficiency with a component capital cost of about $300 per kW electric. Conservatively, assuming a conversion efficiency of 25%, the total cost with the addition of the boiler and chemical components is estimated at $1380 per kW electric. The system applications for distributed power (1–10 MW electric) and central generation retrofit and green‐field projects are projected to be very competitive relative to existing power sources and systems.

“…However, the valve arrangements become more complex with counter-flow arrangement [5]. Reciprocating engines are perceived to be easier to implement than Wankel engines [6]. However the flexibility of operation outweighs the efficiency factor and makes the reciprocating Rankine cycle more practical.…”

Heat recovery bottoming cycles for internal combustion engines have opened new avenues for research into small steam expanders (Stobart and Weerasinghe, 2006). Dependable data for small steam expanders will allow us to predict their suitability as bottoming cycle engines and the fuel economy achieved by using them as bottoming cycles. Present paper is based on results of experiments carried out on small scale Wankel and two-stroke reciprocating engines as air expanders and as steam expanders. A test facility developed at Sussex used for measurements is comprised of a torque, power and speed measurements, electronic actuation of valves, synchronized data acquisition of pressure, and temperatures of steam and inside of the engines for steam and internal combustion cycles. Results are presented for four engine modes, namely, reciprocating engine in uniflow steam expansion mode and air expansion mode and rotary Wankel engine in steam expansion mode and air expansion mode. The air tests will provide base data for friction and motoring effects whereas steam tests will tell how effective the engines will be in this mode. Results for power, torque, and p-V diagrams are compared to determine the change in performance from air expansion mode to steam expansion mode.

“…Available options of volumetric expanders include reciprocating and rotary expanders, but this last solution, which is often based on the Wankel concept [2,4], shows implementation difficulties [1], while reciprocating SEs result in an easier design and construction [5].…”
