contact condenser

[′kän‚takt kən′den·sər]
(mechanical engineering)
A device in which a vapor, such as steam, is brought into direct contact with a cooling liquid, such as water, and is condensed by giving up its latent heat to the liquid. Also known as direct-contact condenser.

Contact condenser

A device in which a vapor is brought into direct contact with a cooling liquid and condensed by giving up its latent heat to the liquid. In almost all cases the cooling liquid is water, and the condensing vapor is steam. Contact condensers are classified as jet, barometric, and ejector condensers. In all three types the steam and cooling water are mixed in a condensing chamber and withdrawn together. Noncondensable gases are removed separately from the jet condenser, entrained in the cooling water of the ejector condenser, and removed either separately or entrained in the barometric condenser. The jet condenser requires a pump to remove the mixture of condensate and cooling water and a vacuum breaker to avoid accidental flooding. The barometric condenser is self-draining. The ejector condenser converts the energy of high-velocity injection water to pressure in order to discharge the water, condensate, and noncondensables at atmospheric pressure. See Vapor condenser

To alleviate these problems, direct contact spray-type condensers can be adopted in replace of the indirect contact condenser. As the dew point of the flue gas decreases with the condensation of water vapor, the temperature of the cold source should be low enough to cool the flue gas so as to reach a high efficiency.
Inspired by the air processor, this paper introduces a liquid-desiccant-based flue gas total heat recovery system combined with a direct contact condenser which can absorb NOx.
Then, it contacts with the cooling water in the direct contact condenser where the water vapor in the flue gas is partially condensed into the cooling water.
The model of the direct contact condenser is also identical to that of the absorber by regarding the cooling water as infinitely dilute solution.
Unlike the traditional condensing boiler and NCHR, the system proposed in this paper will neutralize the condensate with alkali liquor in the direct contact condenser and dilute it by the cooling water with a large circulation flowrate, making the drainage meet the requirements of environmental protection.
This allows the use of a direct contact condenser in the flash steam cycle.
Until the late 1970s direct contact condensers were used to condense turbine exhaust steam.
