1. NUMERICAL SIMULATION OF COAL GASIFICATION IN A CIRCULATING FLUIDIZED BED GASIFIER
Abstract This paper presents a 3D full-loop simulation of a circulating fluidized bed gasifier. The model is validated with experimental results from the literature. The validated model is thereupon used to compare Bubbling Fluidized Bed (BFB) and Circulating Fluidized Bed (CFB) gasifiers to highlight the effect of a change in fluidization regime from bubbli

4. High temperature corrosion in gasifiers
Several commercial scale coal gasification combined cycle power plants have been built and successfully operated during the last 5-10 years. Supporting research on materials of construction has been carried out for the last 20 years by EPRI and others. Emphasis was on metallic alloys for heat exchangers and other components in contact with hot corrosive gase

5. Effects of wet CO oxidation on the operation of engines and power generators
A simplified method is used to determine the optimum water content in the flue gases of charcoal gasifiers to be utilized as alternative fuels in the operation of engines and gas turbines for power generation. Computational models of plug flow reactors and well stirred reactors are employed to simulate the reaction and post-flame zones, adopting different ch

6. Usage of flux method to improve radtative heat transfer modeling inside bubbling fluidized-bed boilers and gasifiers / Emprego do metodo de fluxos para melhorias em modelagens de trocas de calor por radiação em caldeiras e gaseificadores de leito fluidizado borbulhante
Nos últimos 25 anos, um modelo matemático abrangente e o correspondente programa computacional têm sido melhorados e testados para simular a operação em regime permanente de equipamentos de leito fluidizado. Apesar do sucesso, as trocas de calor por radiação têm sido tratadas de modo simplificado. Para temperaturas elevadas, a radiação térmica se
