Description

i

The invention relates to the field of power engineering and can be used in power units of various capacities with circulating water supply with condensers of any type, for example, in air-condensation installations with mixing condensers.

The aim of the invention is to reduce the temperature of the water entering the condensers, which leads to a decrease in the heat exchange surfaces of the apparatuses (condensers and cooling towers).

For this purpose, water-cooled heat exchangers connected in series in a heated medium are included in the cooling water intake and discharge pipelines. They may be included (by the heated medium) in the circuit for heating the make-up water, for example, hot water supply systems.

The drawing shows the proposed system including a cooling device connected by pipes for supplying and discharging water to a turbine condenser, and connected water-conducting heat exchangers.

From the cooling device /, for example from a dry or evaporative cooling tower, through the water supply line 2 to the condenser, partially cooled water enters the water heat exchanger 5, in which it transfers its heat to the cooler body — the make-up water fed to the heat exchanger

3 by means of a pump 4. The heat exchanger 3 is the first stage of heating the make-up water. From the heat exchanger 3, the finally cooled water flows through the conduit into the condenser 5 of the turbine unit 6. From the condenser 5, water, which receives heat from the steam worked out in the turbine installation 6, is pumped through pump 8 via pipe 8 to the water heat exchanger I in which it gives off some of its heat cold body - make-up water supplied to the heat exchanger 9 through the pipe 10 from the heat exchanger 3. The heat exchanger 9 is the second stage of heating the make-up water. From the heat exchanger 9, the water enters the cooling devices 1, and the make-up water, preheated in the heat exchangers 5 and 5, flows through the pipeline 10 to the return line // of the consumer 12 of the hot water supply. By this, the water flow through the condenser 5 of the turbine unit 6 and through the cooling device I is reduced, and also the heat exchange surface of the condenser 5 and the cooling device 1 can be reduced.

Due to the use of waste heat, the steam consumption of the network heaters 13 is reduced, which allows increasing the power at the terminals of the generator 14 at a constant flow of fresh steam to the turbo-installation 6, or to reduce the consumption of fresh steam to the turbo-installation

6 while the generator capacity is unchanged. 14. The more the amount of hot water consumed by the consumer 12, the more positive the effect will be given by the system.
