Abstract
The present disclosure discloses a two-layered varied ball diameter packed bed heat storage apparatus and a method of manufacturing a heat storage ball. By arranging large-diameter heat storage balls at an upper layer of a packed bed heat storage apparatus and small-diameter heat storage balls at a lower layer thereof; the packed bed heat storage structure comprehensively considers two important evaluation indicators for a heat storage apparatus: heat storage rate and heat storage density, thereby implementing a design principle of maximizing the heat storage rate density of the packed bed heat storage apparatus; by achieving a best combination of heat storage ball diameters inside the packed bed through an optimized design, the heat storage apparatus is imparted with a best heat storage performance. The present disclosure further provides a method of manufacturing a heat storage ball.
