煤高效制合成气装置传热特性的模拟研究
Simulation Study on Heat Transfer Characteristics of Coal Synthesis Gas Installations
摘要
Abstract
Based on the Eulerian two phase fluid model and with the use of numerical simulation software Fluent, this paper simulates the coal gasification plant's operation state, and mainly discusses the temperature and void distribution in the coal gasification plant, under the conditions of different inner cylinder radius (Ri) and outer cylinder radius (Ro). After reasonably simplifying the theoretical model and rationally dividing the grid, using Fluent successfully obtains the distribution of the temperature and the solid particulate after the plant runs for 15 seconds. Through analysis and comparison of Fluent data,it is finally concluded that, at the parameters Ro/Ri = 2, Ro/ Ri = 3 and Ro/ Ri = 5, the temperature inside the separator reaches the required preheating temperature of the coal approximately, and in the range of 2 ＜Ro/Ri≤3, the plant's gasification part can achieve a better temperature for gasification and the fluid state is ideal at the same time.关键词
