International Journal of Hydrogen Energy, 1986
Abstract The generation mix of Electricite de France includes a large number of nuclear power plants. This enables E.D.F. to produce cheap off-peak electricity. Therefore electrolytic hydrogen could be produced at low cost. Ammonia manufacturers and other chemical plants are potential consumers.

ON THE COOLING OF GAS TURBINES
Journal of Flow Visualization and Image Processing, 2001This article deals with measurements of convective heat transfer coefficients in three fluid flow patterns that concern both internal and external cooling of gas turbine components; in particular, the flow in a couple of smooth, or ribbed, ducts connected by a 180° sharp turn, a jet in cross-flow, and a jet impinging on a wall for short nozzle-to-wall ...

Industrial gas turbines show performance characteristics that distinctly depend on ambient and operating conditions. They are not only influenced by site elevation, ambient temperature, and relative humidity, but also by the speed of the driven equipment, the fuel, and the load conditions.

Transactions of the American Society of Mechanical Engineers, 1924
Abstract The paper presents a statement of the brake thermal efficiencies that may be obtained from gas turbines of various types, and discusses the possibilities and limitations of these types of heat engines. Calculated performances, with tables of computed values, are given for the following types: (1) Explosion turbine with ...

Gas turbines and combined cycle gas turbines
2015Gas turbines and gas-steam combined plants are presented in this chapter. Their valuable characteristics in the wide field of thermal power plants are the high power-to-weight ratio, the low emissions (CO2, SOx, NOx and particulate), the not high capital cost, the relatively high load variation rapidity, especially for simple cycle turbine engines, the

Rendiconti del Seminario Matematico e Fisico di Milano, 1948
Sono inizialmente discusse le ipotesi semplificative adottate per i successivi sviluppi termodinamici; e quindi definito il rendimento dell’eventuale scambiatore di calore, insieme a determinati fattori di perdite dello stesso; sono poi caratterizzate le trasformazioni, che si svolgono nel compressore e nella turbina, attraverso le quantita di calore ...

The invention relates to a gas turbine (10) having air cooling. The invention provides an effective measure for cleaning cooling air which is used in the turbine (30), which measure is particularly efficient. In order to allow comparatively pure, that is to say particle-free, compressed cooling air to flow into the cooling-channel system (58) of the ...

Technological Forecasting and Social Change, 1999
Abstract The use of gas turbines in the electric industry of many countries has been increasing. Their demand now represents more than 50% of the world market of thermal power plants. In this article we test the paradigm concept to explain the technological change that represents the gas turbine in electricity generation.
