Une turbine à gaz, ou plus exactement turbine à combustion [a] (TAC) [1] est une machine tournante thermodynamique appartenant à la famille des moteurs à combustion interne.. Une telle turbine sert à produire soit du travail, par l'entraînement en rotation d'un arbre lui-même couplé à une machine industrielle ou à une hélice (hélicoptère ou propfan, par exemple), soit une ...

A plumbago, graphite or 'black-lead' quarry was noted from 1791, located at Laigh Dalmore and worked between 1808–1815, milling being carried out at Dalmore Mill. Between 1815 and 1830 William Heron erected a mill to pulverise the graphite but he did not proceed on a commercial scale. Nothing was left to e seen of the deposit by 1935. The mill was then extended and used …

A pulverized coal-fired boiler is an industrial or utility boiler that generates thermal energy by burning pulverized coal (also known as powdered coal or coal dust since it is as fine as face powder in cosmetic makeup) that is blown into the firebox. The basic idea of a firing system using pulverised fuel is to use the whole volume of the furnace for the combustion of solid fuels. Coal is ground to the size of a fine grain, mixed with air and burne…
