Abstract

The boiler-room of a large-scale thermal power plant belongs to super-high industrial building. The heat is concentrated in the upper part of the workshop. In the northern cold region, the wasted heat at the top of the boiler-room can be sent to the main plant-floor by the reversal of the roof-fans. The heat which dissipates from internal equipment is used to provide heating in winter, then the self-balanced heating can be achieved in the plant. In this paper, CFD simulation is used to analyze the high-pressure roof-fan reversing condition in the boiler-room. Combined with the airflow organization simulation results, different multiple airflow relay schemes are constructed through simulating the temperature field and velocity field to optimize the layout scheme of the relays of each equipment layer.
