combustion the harvest and transfer of chemical energy via combustion of the 189 000 scfm of off gases in the boiler unit results in the production of approximately 777 000 lb hr of steam by inputting this amount of steam into the attached steam turbine the accompanying power generator not shown in fig2 generates about 80 mw of electricity the combustion of the 91 000 scfm of off gases at the super heater is sufficient to condition the saturated steam contained therein into an unsaturated or superheated form that is suitable for use in a steam turbine the steam output from the super heater turns the attached turbine and results in the production of approximately 84 mw of electricity by combining the electricity produced by all three of the generators in the present system at the present input rates and amounts and with the assumed efficiencies a total gross power output of 184 mw is achieved this electricity may be utilized for the further operation of the direct iron making process or for any other desired purposes thus the direct iron making process may be made substantially more efficient of course it is to be understood that the above described arrangements are only illustrative of the application of the principles of the present invention numerous modifications and alternative arrangements may be devised by those skilled in the art without departing from the spirit and scope of the present invention and the.
