Abstract:
The present study is a CFD investigation of the gasification behaviour of different of difficult coals at high pressure in the siemens 5-MW piolot-scale entrained-flow reactor. The detailed models for char conversion kinetics are adjusted based on laboratory investigations of the same coals and then coupled to the CFD framework for the full-scale simulations. The gasifiction reactions in entrained-flow reacteors predominantly take place in the so-called pore-diffusion regime. In order to c...    »
