微波高温加热的污泥炭化过程测温方法分析
Analysis of the temperature measurement method for sludge carbonization process under microwave high temperature heating
摘要
Abstract
The paper established a novel temperature measurement method based on Newton's cooling law and the cooling curve,which could calculate high temperature and improve its accuracy.Firstly,a sample was heated to a known high temperature by conventional electrical heating,and then its cool-ing curve was obtained under forced cooling conditions.Subsequently,the formula of temperature and time was fitted,and the value difference between the calculated initial temperature and its actual temperature was compared.The results indicated that the method is feasible.Under forced cooling conditions,the high temperature exhibits a monotonically decreasing exponential function relationship with time,and the value error between the calculated initial temperature and its actual temperature is less than 5%.According to above results,cooling curve test and temperature calculation were conduc-ted for high-temperature samples heated by microwave irradiation,and the temperature difference of about 300℃was corrected by the method.Based on the novel method,the calculated temperature of the sample heated by microwave irradiation meets the requirement for its phase change.关键词
