The environmental friendly, ceramic honeycomb regenerative burner system is worth noting as innovative technology, for its effect of low energy consumption and NOx emission. It is recognized as one of concrete measures to prevent global warming and to solve environmental problems. NKK and Nippon Furnace Kogyo have jointly developed the system and succeeded in starting its practical operation. In NKK, this technology has been already applied to eleven furnaces. NKK has achieved over 30% energy saving effect and over 50% NOx reductions. This system ensures to provide the world with an effective countermeasure for the global greenhouse effect and the acid rain.
