DE2349283A1 - Direct contact condenser for steam power stations - has sparge pipes with injection nozzles for cooling water - Google Patents

Abstract

The condenser has a vertical cylindrical metal casing with a steam inlet central in the base directing steam upwards. A cooling water inlet pipe runs vertically down the centre of the shell from the top. It carries a series of sparge pipes running out horizontally from it and spaced at equal intervals vertically from each other. Each sparge pipe contains a number of injection nozzles which atomise the cooling water and spray a cloud of small droplets in counter current to the upflow of steam. These clouds have a large surface area dn therefore achieve rapid cooling and condensation of the steam in a small volume thus reducing the space taken by the condenser. The same construction can be used for water coolers.

and cooling water,
t'iosef Strakata, G-iessen.

Steam turbines require downstream condensation systems considerable in their execution for surface consistency Dimensions of the container around those formed by pipes of the same diameter To accommodate cooling surface «, large containers and the many Cooling pipes made of brass require high investment costs and require a lot of space and floor space in the power plant »

The recooling systems downstream of the condensers, such as cooling towers, are also large and can occasionally cause unwanted warming of standing or flowing water the same decisive increase ZLi ο

In nozzles of known design, water can be atomized into an infinite number of "small-diameter droplets", for example by detaching the jet at sharp edges with a sufficiently high pressure, and thus its surface area can be enormously increased. Countless droplets among them are potently as Kondensationskemae "Both factors together make gegeniXOer previous compression of steam a greatly increased Condensations- and Kühleff ect _f so for the same quantities of steam per time unit significantly reduced dimensions for both the condenser and for clie ^ iückkühlung gemigen _o In addition, the condensation containers are arranged upright, which saves floor space ^ ifätfä? can _o
