| Abstract: | Regenerative heat exchanger is an important equipment which utilize the heat of the waste gas to preheat combustion-supporting air.For the inner heat transfer performance of it,because of its complexity,the unsteady heat transfer process characteristics of the single ball regenerator was studied first,then derived the calculation formula and used the computer to calculate the process under some certain parameters,drawn figures and analyzed them,found out the different parameters's effects on its indexes,provided theoretic basis for future practical application. |
