Determination of the economical efficiency of schemes of thermochemical recuperation for heat engines
On the example of gas-turbine plants, we have considered the principal and constructive schemes of thermochemical recuperation for the utilization of secondary energy resources, namely, the enthalpy of exhaust gases. We have developed methods of the calculation of thermodynamic and heat-transfer cha...

| description | On the example of gas-turbine plants, we have considered the principal and constructive schemes of thermochemical recuperation for the utilization of secondary energy resources, namely, the enthalpy of exhaust gases. We have developed methods of the calculation of thermodynamic and heat-transfer characteristics of these schemes. We have carried out wide numerical investigations of the technical-and-economical parameters of schemes of thermochemical recuperation and determined their dependences on temperature conditions. We have established that the pay-back period is usually equal to several months, and, hence, thermochemical recuperation is a high-efficiency variant of the utilization of secondary energy resources. |

На прикладі газотурбінних установок розглянуто принципові та конструктивні схеми термохімічної регенерації для використання вторинних енергоресурсів – ентальпії відпрацьованих газів. Розроблено методи розрахунку термодинамічних та теплообмінних характеристик вказаних схем. Проведено широкі числові дослідження техніко-економічних параметрів схем термохімічної регенерації та визначено їх залежності від температурного режиму. Встановлено, що термін окупності схем порядку кількох місяців, отже, термохімічна регенерація є дуже ефективним варіантом використання вторинних енергоресурсів.
