Abstract:
On the base of regenerator configuration character, the heat transfer mathematics models are set up. The relevant relations of regenerator medium, exchange time, temperature efficiency and thermal efficiency are analyzed by numerical simulation. The results are anastomotic by numerical simulation and by experiments after exchanging 7 - 10 s. And it indicts reliability by simulation. The authors study effects of exhaust gas temperature and air preheat temperature influenced by regenerator medium, exchange time etc. , by numerical simulation and experiment. On the case, the suitable exchange time of corundum globule is about 60s, the suitabe exchange time of high aluminum and clay ceramic ball is 20 -30 s. Temperature efficiency is up more than 80%, thermal efficiency is up more than 70%.
