  • What is a Heat Exchanger? How do Heat Exchangers

    Marine Closed 'Freshwater' Cooling systems is a bit of a misnomer as they do not actually circulate freshwater but an antifreeze/water mixture. Unlike in a car where the antifreeze/water circulates through an air-cooled radiator, a closed cooling system uses lake or ocean water flowing through a heat exchanger to remove heat from the engines ...

    1999-2-1 · In the natural draft cooling tower, the necessary air mass flow is caused by density differences (buoyancy). Figure 5 shows the function of a natural draft cooling tower with closed- and open-circuit cooling systems. The heat exchange surfaces are right in the lower part of the tower, producing current by buoyancy. Compared with the mechanical draft system, the advantage is that the natural ...

    As shown in Fig. 13, with the increase of inlet cooling water temperature, the total heat released by flue gas, the heat recovered by cooling water, latent heat and sensible heat all decrease in different degrees, the heat lost by blowdown valve gradually decreases to 0, and the effective heat recovery factor gradually increases to 1. At this time, the heat released by flue gas is all recovered.
