Industrial Furnace Business
Industrial furnace business has also been started at the same time of NFK’s establishment together with burners & combustion equipment business. NFK at the beginning introduced the technology of Heavy Duty Inc. in the US and Birlec Limited in the UK and then has succeeded to develop various kind of original designed heat treatment furnaces. The typical example of them is so called High Performance Industrial Furnaces which are equipped with regenerative burners incorporating a ceramic honeycomb and this technology has been contributing to environmental protection as CO2 and NOx reduction. Especially the patented regenerative radiant tube furnaces in the middle and high temperature range are unique and competitive designed ones and have been receiving client’s satisfaction.

Industrial Fumaces equipped with Reqenerative Burners (HRS Burners)
The HRS burner developed by NFK is a highly efficient, low NOx combustion system with application of the most advanced “High Enthalpy Air Combustion Technology” acclaimed worldwide for its superiority over conventional combustion technologies. NFK is making substantial contributions to the reduction of CO2 and NOx emissions from industrial furnaces used in steel mills, machinery manufacturing, ceramics and other industries by supplying them with industrial furnaces and various combustion systems with the HRS technology.
HRS-DL Retractable Type Heat Treatment Furnace
A batch operation heat treatment furnace with a cover on top. The cover is attached with a hinge mechanism for opening and closing making it suitable for handling of long-sized materials. Although the HRS-DL Retractable Type Heat Treatment Furnace has no charging door, it has several merits such as minimum leakage loss and easy maintenance of the interior. The standard model is equipped with the HRS-DL burners. However, depending on design specifications, the HRS-RT(Radiant tube)burners can be used.
