82Gas-cooled fast reactor — The Gas Cooled Fast Reactor (GFR) system is a nuclear reactor design which is currently in development. Classed as a Generation IV reactor, it features a fast neutron spectrum and closed fuel cycle for efficient conversion of fertile uranium and… …
83Boiler (steam generator) — Contents 1 Steam generator (component of prime mover) 2 Boiler types 2.1 Haycock and wagon top boilers …
84Chemical looping combustion — (CLC) typically employs a dual fluidized bed system (circulating fluidized bed process) where a metal oxide is employed as a bed material providing the oxygen for combustion in the fuel reactor. The reduced metal is then transferred to the second …
85Bearing (mechanical) — A bearing is a device to allow constrained relative motion between two or more parts, typically rotation or linear movement. Bearings may be classified broadly according to the motions they allow and according to their principle of operation as… …
86Reaction engine — A reaction engine is an engine which provides propulsion by expelling reaction mass, in accordance with Newton s third law of motion. This law of motion is most commonly paraphrased as: For every action force there is an equal, but opposite,… …
87Free-piston engine — The free piston engine is a linear, crankless combustion engine, in which the piston motion is not controlled by a crankshaft but determined by the interaction of forces from the combustion cylinder gases, a rebound device and a load device.The… …
88Spray forming — Spray forming, also known as spray casting, spray deposition[1] and in situ compaction,[2] is a method of casting near net shape metal components with homogeneous microstructures via the deposition of semi solid sprayed droplets onto a shaped… …
89Supercritical carbon dioxide — Carbon dioxide pressure temperature phase diagram Supercritical carbon dioxide is a fluid state of carbon dioxide where it is held at or above its critical temperature and critical pressure. Carbon dioxide usually behaves as a gas in air at STP… …
90Uniflow steam engine — The uniflow type of steam engine uses steam that flows in one direction only in each half of the cylinder. Thermal efficiency is increased in the compound and multiple expansion types of steam engine by separating expansion into steps in separate …
