辐射传热对储能设备导热性能的研究

在工业条件下实验研究一种新型“水包火”式辐射加热的传热功率和传热效率,分别在额定电功率为9,18,27,36,45 k W的条件下加热,使水温升高,用温度计测量水的温度变化,在炉膛内插入一支热电偶观察炉膛的温度变化。通过实验研究及理论计算,论证了辐射传热对储能设备的传热效果,随着加热功率的增大,传热功率也增大,且二者呈正相关;传热效率则先增后减,且有一个明显的峰值。

The heat transfer power and heat transfer efficiency of a new type of"fire in water"radiative heating are studied experimentally under industrial conditions.The heat is heated under the rated electric power of 9,18,27,36 kW and 45 kW respectively so that the water temperature is raised.The temperature change of water is measured with a thermometer,and a thermocouple is inserted into the furnace to observe the temperature change of the furnace.Through experimental research and theoretical calculation,the heat transfer effect of radiation heat transfer on energy storage equipment is proved.With the increase of heating power,the heat transfer power also increases,and is positively correlated.The heat transfer efficiency increases first and then decreases,and has an obvious peak value.
