Heat recovery system Naniwa Roki has established for cupola melting process can be applied to all the situations in the industries where exhaust waste heat is generated through whatever processes.
As for the actual applications, please refer to the page of Wuerz-type heat exchanger system.

Let us show the recovery process and its effect based on the calculation of the actual cupola operation:

1. Comparison of cold blast cupola and hot blast cupola
2. Comparison of hot blast cupola and the cupola with exhaust heat recovery system

Next is the slide show demonstrating the renewal process of conventional system to waste heat recovery system.

1. Installation example 1 of Wuerz-type heat exchanger system (from metal type heat exchanger system)
2. Installation example 2 of Wuerz-type heat exchanger system (from Econo-therm system)

As shown above, the introduction of waste heat recovery system can be implemented without any difficulties and with minimum facility area.
This heat recovery system are now being operated with good performance in the plants other than cupola melting plant. (e.g., mineral wool manufacture plant, wood industries (see the picture below), waste material treatment plant, etc.)
