岩石填充床蓄热性能试验研究
Experimental study on thermal storage performance of rock packed bed
摘要
Abstract
The energy storage system can effectively improve the energy efficiency,which is an important way to solve the energy supply and demand imbalance and renewable energy instability in recent years,so it becomes the focus all around the world.The packed bed is one of major forms of thermal energy storage,which is a heat storage that is full of filling material.From the economic and technical point of view,the most commonly used and most reliable filling materials are rock and pebble.Taking high pressure air as a heat transfer fluid,the heat storage characteristics of rock packed bed are analyzed in the article,the heat storage efficiency is discussed and researched at different experimental parameters.The results show that the heat storage efficiency of the cycle is reduced with increasing air pressure,increases with increasing air mass flow.With a larger air mass flow and a lower air pressure,a higher heat storage efficiency can be obtained.关键词
