The Rotary Hearth Furnace Designed for Saving Energy

Abstract

A Rotary Hearth Heating Furnace has been designed and installed for both saving energy and reducing NO_x emission. The characteristic of this furnace is as follows.
(1) The ceramic fiber lining is used.
(2) The Low-NO_x 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 NO_x emission to 40% of that by the conventional type furnace.
This paper refers to the outline of this new furnace.
