The heat transfer process of heat exchanger in different working conditions is analyzed by means of CFD simulation, and the optimal structural design is used to avoid the phenomenon of local dead zone and residence.
1.Analysis of internal flow field of air preheater
The velocity field and pressure field of the flue gas passage and air passage are simulated by fluent ANSYS software. Through the simulation analysis, the distribution of the fluid distribution is not uniform, and the structure optimization design is adjusted.
2.Performance analysis of internal heat transfer and resistanceThe flow and heat transfer of the pure counter current plate are analyzed, and the fluid distribution and the heat transfer area are in the air.
