method of thermoeconomic optimization separate section a typical sugar plant. was developed. Since the main part exergy losses is due to heat transfer at finite temperature difference, value drop in each s chosen as an independent variable with corresponding search for their minimum costs. The existence local fact that increasing increases amount energy costs (because increase) and decreases ca...

Three alternatives for integrating a solar field with the bottoming cycle of a combined cycle plant are modeled: parabolic troughs with oil at intermediate and low cycle pressures and Fresnel linear collectors at low cycle pressure. It is assumed that the plant will always operate at nominal conditions, using post-combustion during the hours of no solar resource. A thermoeconomic study of the o...

Abstract The organic Rankine cycle (ORC) power plant is derived from a centrifugal chiller air conditioning system as an alternative to diesel replacement modular due its low cost compared ORC’s manufacture. Biomass used heat source for the utilize vast amount of biomass in Indonesia. Research performed by designing ORC with that produces around 200 kWe. Simulation done Microsoft Excel and Refe...

Abstract The United Nations action plan Agenda 21 has represented a milestone toward Sustainable Development. On its 40th Chapter, it is introduced the requirement to dispose of an accurate and continuous collection information, essential for decision-making. Besides bridging data gap improving information availability, highlighted need sustainable development indicators, in order assess monito...

Enerji verimliliği, küresel ısınma ve iklim değişikliği günümüzde üzerinde durulan en önemli konuların başında gelmektedir. Tüketilen enerjinin etkin verimli kullanımına ilişkin yeni tasarımlar yaparken de tasarımlarda kullanılacak yenilikçi teknolojiler ekonomi çevresel olumsuz etkilerin azaltılmasına katkı sağlayacaktır. Bu çalışmada; tamamen gaz yakıcı bir cihazla çalışan döküm sektöründe ku...
