Tower leading line opens. * ~ In the drawing is a thermal power plant 1 Such a power plant is shown from the magazine, which requires significant amounts of cooling water "fuel - heat - power", 22, no. 5, May 40. The power plant 1 can, for. B. a konventio-1970, page 233, known. nelle, fossil fuel-heated power plant This type of power plant must, in particular, be a nuclear reactor plant. For the removal of a full cooling water from a river 2, a cooling water-independent separation of the water through one or more channel 3 is provided, at the end of which there are several cooling towers leading circuit of the water 45 cooling water pumps 4,
be possible that the water, z. B. a river The cooling water pumps 4 promote the cooling water or a lake, is taken. In this case, from the cooling water duct 3, a conveyor line is normally used to convey the cooling water into the power plant 1, where B. for cooling rere parallel-connected cooling water pumps upstream of steam condensers, is used. The heated cooling, which for economic reasons has high specific 5 ° water is fed through a pipe 6 with a fish speed, with a large delivery shut-off element 7 to a discharge channel 8, the quantity and small delivery head. Such cooling back into the river 2 flows,
Water pumps are very sensitive to inlet conditions. In addition, the power plant is very sensitive to cooling the water fed to it. The tower 10 is provided for cooling water, to which the inlet may only contain small speed differences 55 cooling water through one of the pipeline 6 in front of and no eddies. In addition, the pipeline 11 branched off from the shut-off device 7 to these cooling water pumps is usually controlled. In the pipeline 11 there is a delivery rate by adjusting the rotor blades. Shut-off element 12. The inlet conditions that are cooled in the cooling tower 10, even with water, must be collected in a basin 13 and consistently good from different delivery rates. 60 this is fed to a connection channel 14, from wel-It is the task of creating a device to formerly.
