Оценка термодинамической эффективности ТЭЦ

Оценка термодинамической эффективности ТЭЦ

Abstract

Традиционная оценка работы ТЭЦ на базе широко известных характеристик, таких как удельный расход условного топлива на выработку электроэнергии и отпуск тепловой энергии не дает полной картины и не всегда применяется корректно. В работе впервые на базе эксергетического метода и соответствующего эксергетического КПД проведена оценка термодинамической эффективности работы ТЭЦ энергосистемы Беларуси. Определены наиболее совершенные ТЭЦ с термодинамической точки зрения. Получена количественная оценка термодинамической эффективности крупных и малых ТЭЦ энергосистемы за годовой, отопительный и межотопительный периоды. Сделан вывод о целесообразности рассмотрения работ по дальнейшей реконструкции ТЭЦ с целью повышения эффективности использования природного газа на ТЭЦ. Traditional assessment CHP based on classical characteristics such as standard fuel specific consumption for electric and heat power generation is not always correct. This paper shows novel thermodynamic effectiveness assessment based on exergy method and exergy efficiency CHP of the Belarussian power grid. Most thermodynamically complete cogeneration power plants of the energy system are defined. The thermodynamic efficiency quantitative assessment of large and small CHPs of the energy system for the year, heating and non-heating periods has been obtained. It is concluded that it is expedient to consider work on the further reconstruction of the CHP in order to increase the efficiency of the use of natural gas at the CHP.
