Small power units fuelled by agro-residues and industrial waste heat

This paper presents a discussion on energy and development with reference to India and brings into focus the importance of small power units (30–300 kW) fuelled by agroresidues and industrial waste heat. It examines the present status of these units and points out that the steam based systems excel over others in such features as conversion efficiency, robust operation and maintenance. The design and performance characteristics of steam based units developed at the Australian National University are outlined; the technology has been operational for about 10 years using steam generated by solar collectors. The nett present cost (NPC) calculations show that the commercial unit is likely to be significantly less expensive for periods over 6 years.
