炼油化工企业火炬放空燃烧仿真模拟的应用

摘要

通过介绍目前燃烧仿真模拟的大型商业CFD软件（ANSYS CFX 和KFX），并运用ANSYS CFX软件对某厂实际案例进行模拟计算，定量分析火炬燃烧特性（火焰高度、烟气抬升高度、温度场分布、燃烧产物扩散等）。结果表明：通过火炬放空燃烧仿真模拟后，才能准确地定量分析火炬放空燃烧的各种特性，才可为火炬设施的设计提供准确的输入条件和可靠的依据，在实际项目的运行中具有一定的指导和借鉴意义。%An actual case in a refinery was simulated using ANSYS CFX, by introducing current classic business software ( ANSYS CFX and KFX) for simulation of combustion, and analyzing combustion characteristics, including flame height, rise-height of smoke, temperature site distribution, dispersion of combustion product, etc.quantitatively.The results showed that after flare gas combustion simulation, combustion characteristics can be analyzed quantitatively, accurate input conditions and reliable basis can be provided for flare facilities designing, and some guidance and reference can also be used in actual project running.
