Abstract
The paper covers a unique development by the Surface Division of Midland Ross of a radiant tube heating element which will heat an industrial furnace with either gas or electric without any down time or physical conversion required. This 'electrified radiant tube' enables a customer to select the fuel he would like to use in any specific period of time from an economic standpoint and would also in case of interruption be able to continue with this processing by simply switching from a electric or gas primary fuel use to the alternate energy source.
