Increasing Cooling Towers Heat Capacity by Flue Gas Introduction

In this paper the changes in the heat capacity of cooling towers has been investigated as a result of injecting combustion products of boilers. In the tower, the air is re-heated through mixing with hot flue gas after passing through the heat exchangers. As a result of this process, the draft of the cooling tower is increased. The additional produced draft depends on the ambient temperature and the amount of heating. The results of the study show that the heating process is more effective in the hot weather than in the cold weather.
