【 摘 要 】

In order to study the combustion temperature distribution of the fire tube and flue tube of the large cylinder natural gas heater with intermediate heat carrier medium, and to select a more appropriate combustion method, this paper separately simulates two kinds of combustion methods: premixed combustion and diffusion combustion. Using a standard turbulence model to describe the turbulent conditions of the flue gas, the turbulent diffusion combustion model and the vortex crushing model were used to simulate the diffusion combustion and the premixed combustion respectively. The results show that this structural model is more suitable for the diffusion combustion method.
