Abstract

The use of computational fluid dynamics (CFD) is becoming more common and reliable as a tool for kinds of buildings fire safety design, but it is not easy to be validated. In this paper, Fire Dynamics Simulator v5.0 is used to investigate the spill plume and the resultant natural filling in the underground transport passage of main transformer of a hydropower station due to the adjacent main transformer hall fire. Ceiling jet temperature decay along the transport passage and smoke layer interface height are simulated. Series of scale model experiments are carried out using pool fires placed at the centre of the main transformer hall. The data obtained from these experiments are later used in a validation study of the FDS simulated results. The FDS simulated results are also compared with the expressions proposed in the literature. The results show good agreement between experimental and numerical predictions. And through suitable adjustment of the constants of the exponential equation, good agreements are also found between the predicted data and calculated results.

Abstract

China's coal consumed has caused inevitable environmental problem in the country. In the context of eco-economic, we put forward a full life cycle modeling and five clean coal inversion technologies. In this paper, a life cycle assessment (LCA) is employed for material consumption and environmental emission research. Incorporating up-to-date data, the study gives a brief economic discussion which covers the decision-making theory in this field and comes up with new technologies for the future.

Keywords

Clean Coal, Environmental Impacts, Inversion, Life Cycle Assessment.
