A Mobile Solar-Dish Gas Turbine Hybrid
摘要
Concentrated solar power systems utilise the sun to redirect solar rays towards a focal point, enabling thermal energy capture. The system investigated in this paper utilises a hybrid gas-turbine cycle to generate electric power and heat using concentrated solar energy and liquified petroleum gas (LPG) as energy sources. Electricity is generated from the output shaft of the micro-turbine, whilst high-temperature exhaust gases can be used for melting and heating processes. This paper aims to investigate the prospects of a mobile prototype version being prepared for testing in an operational environment. Theoretical results are presented using existing solar data to predict the system’s performance in terms of fuel consumption in Pretoria, South Africa. Results show that in the middle of a typical day in spring, the hybrid cycle will use 39% less LPG to operate. Furthermore, this paper presents the key components of a mobile solar-dish gas turbine hybrid setup for demonstration in a rural area.
