Development of a mathematical model of a recycling cooling system of a thermal power plant

Abstract

In thermal power plants in Uzbekistan, the drainless recycling cooling system is widespread, in which water of the most favorable and constant quality and heated in the condenser turbines are used in the water treatment plant thermal power plant. Since the recycling cooling system uses technical raw water, low solubility deposits (scale) are formed on heat exchange surfaces in turbine capacitors. It is believed that the cause of precipitation is the concentration of low soluble water components by evaporation of water in cooling towers. Due to the low thermal conductivity of the deposits formed on the heat exchange surface of the capacitors, the temperature pressure increases. As is known from the scientific and technical literature, the pressure in the turbine capacitors depends on the contamination of the cooling surface. Because of this, the vacuum worsens. The deterioration of the vacuum leads to an over-consumption of steam. Thus, the aim of this work is to increase the operational efficiency of the recycling cooling system of the thermal power plant.
