  • The dual fluidized beds experimental set up is made of transparent perspex material. The system consists of a fast bed riser, a cyclone to separate the solids, a down comer with a L- valve, a bubbling fluidized bed and a return pipe with another L-valve. The system is shown schematically in Fig 1. The solids after passing through the fast bed riser gets separated in the cyclone, descend downwards through the down comer and enter the bubbling bed reactor through the L-valve. A part of bed materials in the bubbling bed system are then transferred back into the...

  • With increasing energy demands, dwindling fossil energy resources, and environmental concerns associated with criteria pollutants and greenhouse gases, significant attention in the power generation community has been focused on increasing efficiency and reducing emissions. A highly efficient and low-emission concept is the fuel cell gas turbine (GT) hybrid. Hybrid systems are comprised of fuel cells integrated with a GT engine. A variety of potential configurations have been proposed and a number of cycles have been investigated.

  • Road traffic is one of the major consumers of energy, particularly in western industrialized countries, and globally it exhibits the highest growth rate in energy consumption of all sectors. In the Organisation for Economic Cooperation and Development (OECD) countries, more than 33% of the total final energy consumption goes into the transportation sector, amounting to more than 11% of the world’s total primary energy consumed.

  • This article concerns the rationale, history, principal issues, and potential of fuel cell-powered rail vehicles. Issues include fuel cell type, hydrogen storage, special factors affecting fuel cell rail, and the question of which rail applications are appropriate for hybrid powertrains. It concludes with a brief discussion of a supersonic concept vehicle, a cross between a train and an airplane that operates in a hydrogen-filled tube and levitates on a gas film, thereby overcoming an inherent efficiency limitation of aircraft. ...

  • The discovery of Shigella as the etiologic agent of dysentery—a clinical syndrome of fever, intestinal cramps, and frequent passage of small, bloody, mucopurulent stools—is attributed to the Japanese microbiologist Kiyoshi Shiga, who isolated the Shiga bacillus (now known as Shigella dysenteriae type 1) from patients' stools in 1897 during a large and devastating dysentery epidemic. Shigella cannot be distinguished from Escherichia coli by DNA hybridization and remains a separate species only on historical and clinical grounds.

  • Technological improvements might also involve the adoption and use of alternative fuel or alternative propulsion vehicles. In developing countries, the most commonly discussed alternative vehicle strategies include compressed natural gas (CNG), liquefied petroleum gas (LPG), alcohol-based fuels, and electric propulsion or hybrid -electric vehicles in certain applications. Other alternative fuels showing potential long -term promise in the transport sector include hydrogen fuel cells and various synthetic fuels for use in compression-ignition engines.
