Lignite Gasification - Mathematical Modeling of Syngas Equilibrium Composition

Popis výsledku v původním jazyce

High-temperature reactor (HTR) is a generation IV nuclear reactor with high efficiency of electric energy production. The output temperature of HTR coolant can be higher than 1000 oC, which is suitable for its further use in other high-temperature applications (so called cogeneration). One of possible cogenerations is a coupling of the HTR with a gasification unit, at which water steam used as a gasification media is produced using HTR heat. In our work, we modeled lignite-gasification process, which utilizes heat from the HTR. For this purpose, we developed a mathematical model of a gasification unit. The model is based on calculation of chemical equilibrium, which plays a crucial role in composition of syngas (synthesis gas) generated during a gasification process. Moreover, chemical equilibrium, as a thermodynamic phenomenon, indicates the upper limit of the gasification process efficiency. We studied the equilibrium syngas composition and its dependency on various operation conditi
