Large scale field erected air cooled industrial steam condenser having heat exchanger panels with primary and secondary condenser sections, in which the secondary condenser section comprises 10% or less of the total heat exchanger, and in which the tubes of the primary condenser sections have narrowed outlet orifices having an area that is 50% or less than the cross-sectional area of a corresponding tube. The invention permits the reduction of secondary condenser tubes while reducing the outlet header pressure sufficiently to minimize backflow, sweep non-condensables and prevent the formation of dead zones.

A multi-functional slurry processing system (VARCOR) and associated methods is disclosed. The present examples provide a multi-functional slurry processing system incorporating systems and methods for separating liquid and solid components in slurries. In particular the systems and methods described herein produce clean water, dried solids, and potential concentration of desirable constituents with a boiling point lower than water. At least one example of the multi-functional slurry processing system provides a self-contained processing facility configured to efficiently convert high water-content slurries into its constituent solid and liquid fractions and subsequently generating and collecting clean water and concentrating desirable constituents with a boiling point lower than water. The multi-functional slurry processing system advantageously applies thermodynamic principles in a system which may include various combinations of a preheater, a degassing unit, a dryer, a steam filter, a compressor, a concentrating tower, and a condensation unit.

A closed loop cooling system can include a first condenser having a first inlet to receive a cooling media for removing heat from a heat source, a second condenser having a second inlet to receive the cooling media, and a header for being plumbed between a heat source and the condensers. The second condenser can be plumbed in parallel with the first condenser. The header can receive the cooling media from the heat source and selectively distribute the cooling media to either or both of the condensers. The header can have a first outlet fluidically coupled to the first inlet and a second outlet fluidically coupled to the second inlet. The second outlet can be located on the header at a lower elevation than the first outlet.
