炉内燃烧场数值模拟研究
Study on the Numerical Simulation of the Combustion in the Burning Furnace
摘要
Abstract
In order to deeply study the combustion in the main burning furnace used in sulfur recovery unit, the three-dimensional solid model of burning furnace is set up with reference to the existing building. On the basis of the operation parameters of Zhongxian Natural Gas Purification Plant, the combustion components and entry conditions are set up; one should adopt the realinzable turbulence model and the analysis of EDC combustion model to simulate the combustion in the main burner furnace. The results showed that the method reflect the situation in the burning furnace; the structure of the furnace in service can promote heat convection among gas, and make gas mix strongly; the most intense reaction occurs in the flame region, where sulfur is increases fastest in the flame zone; meanwhile, increasing the mix effectiveness of gas in the inflamer is beneficial for reaction, Gas at the exits of burning furnace is not well-distributed, and the velocity close to lining was high, which indicates that the structure of tracery wall and arrangement need to be improved.关键词
