Solar cookers may be generally classified into direct and indirect types. The direct types include the box type and parabolic type, while the indirect types include the vacuum tube based cookers. This paper reviews the gradual progress made in the second type. The energy and exergy analysis of a...

An LPE (low-pressure economizer) based waste heat recovery system for a CFPP (coal-fired power plant) is investigated thermodynamically. With the installation of LPE in the flue before the FGD (flue gas desulfurizer), the heat contained in the exhaust flue gas can be recovered effectively and...

Energy and exergy analyses of native cassava starch drying in a tray dryer were carried out to assess the performance of the system in terms of energy utilization, energy utilization ratio, energy efficiency, exergy inflow and outflow, exergy loss and exegetic efficiency. The results indicated...
