Mathematical model of steam turbine condenser [Текст] / NG Borissova, MD Shavdinova // Қазақстан Республикасы Ұлттық инженерлік академиясының хабаршысы. - 2021. - №2. - б. 41-46
ББК 22.1
Рубрики: Математика
Кл.слова (ненормированные):
condenser -- diagnostic model -- mathematical model -- calculation methods -- efficiency -- конденсатор -- диагностикалық үлгі -- математикалық үлгі -- есептеу әдістемелері -- тиімділік -- диагностическая модель -- математическая модель -- методики расчета -- эффективность
Аннотация: The paper analyses the existing calculation methods for steam turbine condenser. The refined methods for calculating the condencer have also been considered. The dependency of the vapor pressure in the condenser on the temperature of the cooling water and the steam flow rate into the condenser have been considered. It can be seen from the obtained dependencies that the calculation of the condenser according to the ARTI and HEI methods coincides with the passport data. It is recommended to use the ARTI and HEI technigues for eguipment diagnostics and to use the KTP and USTU -UPI technigues when studying ways to increase the efficiency of the condenser. The mathematical model of the KG2-6200 condenser has been tested at the Almaty CHPP-2.

Аннотация: The paper uses the method of economic, environmental and mathematical modeling. The management methods that are most effective in terms of "environmental" and "production" criteria are selected. This selected most effective method of management is not an easy task It is proposed to use the method of economic, environmental and mathematical modeling on a computer to solve it. The results of this simulation can be used in decision-making in the fields of ecology, health, industry medicine, investment planning, urban planning, and other areas of industry.
