Flow Field Simulation Analysis of the Inner Stack of Coal-Fired Power Plant

Abstract:

The flow field of inner stack of one coal-fired power plant in Shanghai was simulated. The results showed that there was a larger turbulent region at the upper parts of the entrance in the stack. The inner wall at the opposite of the entrance withstands a much greater shock, and this region is badly worn. The speed in the central and upper region is more stable. The stack is basically running in a vacuum state, which contributes to corrosion mitigation. The temperature shows a decrease trend with the increase of height in the range of 10°C. The temperature of the center part is slightly higher than the ambient part. And with the increase of the stack height, the radial temperature gradient increases.
