In my country there are many years for regenerative furnace replacing heat exchange furnace.

蓄热炉替代换热炉在我国已有十几年了，究竟节能与否值得探讨。

Base on the model of heart transfer in the ladle, the article analyzed the heart transfer of exhaust gas in ladle. This result can be used for the optimal design of regenerative heat exchange device.

通过建立钢包传热模型，对钢包内的烟气进行传热分析，最终确定烟气进入蓄热体前的温度，为烘烤设备的设计提供参考。

Formerly, researchers took attention to one aspect, for example, it was about generating hydrogen by catalytic reforming or regenerative heat exchange.

以往的研究者只关心一方面，主要研究催化重整制氢，或者是蓄热式换热等。
