METHOD FOR CONVERTING CHEMICAL ENERGY INTO MECHANICAL ENERGY AT HIGH TEMPERATURE

WIPO Patent Application WO/2022/121193

A1

The present invention relates to a method for directly converting chemical energy into mechanical energy at a high temperature. The method is characterized in: uniformly mixing calcium oxide powder, aluminum oxide powder, and silicon oxide powder to obtain a mixed powder; and then placing the mixed powder into a non-cylindrical corundum crucible that has a piston-type cover, placing the crucible in a high-temperature furnace, raising the temperature to 1600-1750°C and maintaining the temperature for 0.5-3 hours. During the temperature maintaining process, chemical energy of a reaction between melt obtained after the mixed powder is molten and the aluminum oxide in the crucible is converted into kinetic energy of the melt, so that the melt upwells along an included angle between inner walls of the crucible to form a peak shape, and the kinetic energy of the melt upwell can drive the piston-type cover to form a mechanical motion, thereby converting the chemical energy into mechanical energy at the high temperature. According to the present invention, chemical energy can be directly converted into mechanical energy at a high temperature, so that a foundation can be laid for the efficient conversion and utilization of chemical energy at a high temperature.
