| Abstract: | Effects of spray water rate and inter-tube air velocity on the heat transfer performances of evaporative exhaust steam condenser are investigated by means of established experiment platform. The results show that the optimal spray water rate range is 0.4-0.5 L·m-2·s-1, and during the test range, the heat transfer performance of evaporative exhaust steam condenser increases with inter-tube air velocity adding. Under the optimal spray water rate and inter-tube air velocity, the effect of steam flux on condenser performance is investigated as well. |
