Abstract
In order to optimize the performance of thermal power equipment,the thermoelectric properties,thermal conductivity and environmental compatibility of cuprous selenide and MXene materials are analyzed,and thermal power equipment structures for high and low temperature environments are designed.The experimental method includes the use of high temperature furnace and refrigeration equipment to simulate the actual application environment,and the stability of the experimental conditions is ensured by an accurate temperature control system.Focus on energy conversion efficiency,environmental pollution,durability and reliability of materials and other indicators,and data such as input/output heat and electricity ratios,waste gas and wastewater emissions,and material service life are quantitatively evaluated.The results show that the energy conversion efficiency of cuprous selenide at high temperature is increased by about 30%,and that of MXene at low temperature is increased by about 20%.The application of these two materials also significantly reduces environmental pollution,reducing emissions of waste gas,wastewater and solid waste by about 20%,15%and 10%,respectively.At the same time,the durability and reliability of cuprous selenide and MXene are improved,extending their service life by approximately 25%and 20%,respectively,and remaining stable in periodic performance tests.
