La gazéification du charbon est très ancienne mais ce n’ est que récemment que, grâce au développement des turbines à combustion et à l'expérience industrielle de la gazéification des produits pétroliers, des centrales de production d’électricité IGCC [gazéification du charbon intégrée à un cycle combiné] ont vu le jour. Dans cette filière, un gaz, produit par la gazéification sous pression du charbon(à l'air ou à l'oxygène), est refroidi puis épuré aussi soigneusement que possible afin de servir de combustible dans une turbine à combustion dont les fumées à haute température permettent de générer de la vapeur pour alimenter une turbine à condensation classique. 2, record 1, French, - gaz%C3%A9ification%20sous%20pression

Record number: 2, Textual support number: 2 DEF
The calorific content of the total useful heat or energy produced by a plant, expressed as a percentage of the calorific content of the total fuel consumed, or simply: heat output [divided by] heat input [multiplied by] 100. 4, record 2, English, - thermal%20efficiency
Record number: 2, Textual support number: 2 OBS
In respect of a boiler, "heat output" relates to the energy value of the useful hot water or steam produced. In considering electricity generation, however, the overall thermal efficiency is the total energy value of the electricity "sent out", expressed as a percentage of the energy value (gross as fired) of the fuel used. This overall concept takes account of both boiler and steam turbine losses. A modern power station achieves about 35 per cent thermal efficiency. 4, record 2, English, - thermal%20efficiency
Record number: 2, Textual support number: 3 OBS
Compare with "heat rate", a related concept which some authors consider as a synonym of "thermal efficiency". 5, record 2, English, - thermal%20efficiency

Le perfectionnement des RHTRG [réacteurs à haute température refroidis par gaz] aura pour but d’améliorer la performance et de prolonger la durée de vie des centrales. Pour le premier point, de nombreuses recherches sont actuellement consacrées à ce que l'on appelle le cycle à turbine à gaz, où un gaz à haute température alimente directement une turbine à gaz ce qui permet d’obtenir un rendement thermique très élevé et un coût de l'énergie très intéressant ainsi qu'à la production de chaleur industrielle à très haute température. 2, record 2, French, - rendement%20thermique
