Improving the efficiency of a tower-type water cooling device during the warm season for the climatic conditions of the Republic of Tatarstan

RELEVANCE. The relevance of the study is due to the increasing demands for energy efficiency of industrial enterprises in the context of climate change. Cooling towers are key elements of water recycling systems at enterprises in the petrochemical and energy industries of the Republic of Tatarstan. TARGET. To analyze modern approaches to increasing the efficiency of cooling towers in the warm season, taking into account the climatic conditions of Tatarstan, and also to study the possibility of using an evaporative air cooling system in front of the air intake windows of a cooling tower of a thermal power plant. METHODS. To achieve the set goal, an analysis of literary sources and technical documentation of the operating facility, thermodynamic calculations of heat and mass transfer processes of evaporative cooling of circulating water and the influence of its temperature on the operation of the steam turbine unit were used. RESULTS. The implementation of the outdoor air pre-cooling system is a technologically sound solution for optimizing the operation of cooling towers under conditions of increased temperature loads. This system ensures thermodynamic stabilization of the heat exchange process by reducing the temperature of the incoming air flow. CONCLUSION. The implementation of this engineering solution ensures the stable operation of the cooling system in a wide range of meteorological conditions while maintaining technological parameters throughout the year. The introduction of pre-adiabatic air flow cooling technology contributes to a significant increase in the energy efficiency of the power unit, namely: turbine power increase: 492 kW; annual additional energy production: 1.7 GWh; economic effect: 14.67 million rubles / year; payback period of less than 2 years.
