| Abstract |
The paper discusses small power plant developments. Examples have been drawn from world-wide geothermal developments, presenting different views on how a resource can be developed, and the equipment required. Each field has specific in of theeconomicsand thermodynamicsof Alternative for the equipment of power are also discussed; for example, condensingand back pressure machines, binary, biphase, etc. Thermodynamics performance parameters are presented, demonstrating where the inefficiencies occur in geothermal plant and highlighting that thermodynamic as well as economic parameters must be considered when planning the developmentof a geothermalresource. The discussion draws New Zealandexperienceand published studies both in New Zealand and world wide in the utilisation of large and small scaleplant. |
