Abstract

A Rotary Hearth Heating Furnace has been designed and installed for both saving energy and reducing NOx emission. The characteristic of this furnace is as follows.
(1) The ceramic fiber lining is used.
(2) The Low-NOx Burner with high efficient combustion is developed.
(3) The combusion control with O2% is adopted.
As a result of those improvement of the efficiency, the amount of town-gas consumption was reduced to 70% and that of NOx emission to 40% of that by the conventional type furnace.
This paper refers to the outline of this new furnace.
