Countries all over the world are looking for fuel to replace fossil energy due to environmental concerns and a scarcity of fossil fuels. Oil shale (OS) and rice husk (RH) are both viable fuels, although they both have issues like high ash content and poor calorific value. OS and RH were used as feedstock for high-quality fuel in this study, which uses a hydrothermal technique to provide a novel way to utilize OS and rice. At different hydrothermal temperatures (150, 200 and 250 °C), including combustion and pyrolysis processes, the thermogravimetric analyzer (TGA) was used to analyse thermal transformation characteristics of co-hydrothermal carbonization (co-HTC) of OS and RH, as well as the synergistic effects. Results showed that the co-HTC pretreatment had a significant effect on the thermal transformation behaviour of OS and RH. On the one hand, the co-HTC has higher volatile content than its calculated value. On the other hand, a synergistic effect was found in combustion processes, and this effect was the most obvious when the hydrothermal temperature was around 200 °C, and the characteristic peak of functional groups vibration was strong. Therefore, the co-HTC was considered suitable for combustion. The combination of co-HTC modification with subsequent thermochemical processes has positive implications for the energy production and utilization of organic waste.
After decades of development, electricity has become an important driving force for national economic construction, and countries’ dependence on electricity is also increasing. In order to solve the problems of environmental pollution and nonrenewable resources in the process of traditional energy power generation and further improve the utilization efficiency of electricity, countries have vigorously developed new energy grids. As a rapidly advancing developing country, my country has a huge demand for electricity. In addition, in recent years, my country’s new energy power generation technology has advanced by leaps and bounds, and it has become an extremely important source of electricity, which is necessary. The purpose of this study is to improve the power grid dispatching and facilitate the people through the understanding of new energy sources with high penetration rate. This paper mainly uses the experimental method, the comparison method, and the investigation method and uses the big data technology to analyze the use of new energy and the optimal dispatch of the new energy grid. The experimental data show that the load changes in each time period are within 1. Through the continuous testing and optimization of the objective function, the dispatching of the high-penetration new energy grid has initially achieved scientific overall planning. The development of this research will help to realize the optimal configuration between traditional energy power generation and new energy power generation and realize the sustainable development of new energy power generation while reducing the loss of grid connection.
In order to reduce the uncertainty of coincidence measurement, a β-γ coincidence measurement system based on digital technology is designed. The system consists of data acquisition hardware and data analysis software. It uses the data acquisition card to collect data from the detector, and then finish the dead time correction, coincidence resolving time correction and efficiency extrapolation necessary for coincidence measurement on the computer. The designed coincidence measurement system is used to measure 60Co standard source in the laboratory, and adopt two efficiency extrapolation methods to process the measurement results. The results show that the deviation of the activity of 60Co standard source measured using the designed coincidence system from the value measured using a standard device is less than 0.5%.
