53.1 AIR-HEATING PROCESSES. Air can be heated by burning fuel or by recovering waste heat from another process. In either case, the heat can be transferred to air directly or indirectly. In waste heat recovery, the heat exchanger is termed a recuperator.. Direct air heaters or direct-fired air heaters heat the air by intentionally mixing the products or combustion of...

PRODUCTION PROCESSES Fission Fusion 1712 56.7 CHARACTERISTICS OF THE. Most of the fusion systems now being investigated for civilian applications are far removed from weapons technology. Until the passage, in 1954, of an amendment to the Atomic Energy Act of 1946, almost all of the technology that was to be used in developing commercial nuclear power was classified. industry to...

This cycle is one of the four that account for most of the heat engines in use. The Rankine cycle involves condensing and boiling of the working fluid, steam, and utilizes a boiler to transfer heat to the working fluid. This chapter was written as an update to chapter 72 of the Handbook's previous edition. Much of the structure and...

57.1.5 Gas Turbine Operation. This is provided by an electrical motor or diesel engine connected through a gear box to the shaft of the gas turbine (the high-pressure shaft in a multishaft configuration). Below self- sustaining speed, the component efficiencies of the compressor and turbine are too low to reach or exceed this equilibrium.. This reduces the thermal gradients experi-...

59.3.1 Experimental. A combustion process, during which the chemical energy of the fuel is converted to thermal energy of the products of combustion. An expansion process, during which a portion of the thermal energy of the working fluid is converted to mechanical energy. An exhaust process, during which most of the products of combustion are expelled from the combustion chamber....
