Heat Transfer

When high-temperature gases or steam enter the plate condenser, they come into contact with the plate surfaces of the plate bundle, initiating the heat transfer process. The heat from the high-temperature gases or steam is transferred to the cooling medium through the plate surfaces, raising its temperature. The primary modes of heat transfer are conduction and convection. As heat is transferred, the temperature on the plate surfaces gradually decreases. When the temperature drops below the saturation temperature of the gases or steam, the water vapor within begins to condense into liquid.

Condensation and Mass Transfer

Apart from water vapor, high-temperature gases or steam may also contain other gaseous components. As these gases pass through the channels of the plate bundle, due to temperature reduction and pressure changes, some gaseous components may undergo chemical reactions or physical adsorption and adhere to the plate surfaces. This phenomenon is known as condensation and mass transfer. The occurrence of condensation and mass transfer enables the plate condenser to not only transfer heat to the cooling medium but also remove impurities and harmful substances from the gases.
