Electric Furnaces for Making Iron and Steel

Description: From Introduction: "Some results of the work already done are presented in this bulletin, which gives a historical review of the development of electric furnaces for making iron and steel, and discusses the problems that remain to be solved in the use of electric furnaces for the smelting of iron ores and the production of pig iron at a profit on a commercial scale."

The Electric Furnace in Metallurgical Work

Description: From Introduction: "This bulletin presents a compilation of such data as seem to be useful for the information of persons who may be interested in the matter. In the application of electricity to metallurgy three kinds of processes are involved, namely, mechanical, thermal, and electrolytic."

Combustion of Coal and Design of Furnaces

Description: From Purpose and scope of Investigations: "The combustion investigations of bureau are carried on in two parts. One part is the study of the process of combustion in the fuel bed as affected by the rate of supplying air through the fuel bed, by the character of the fuel as regards structure and composition, by the thickness of fuel bed, by the method of feeding the coal and the air and by the method of heating the coal. The second part of the investigation is the study of the process of combustion of the gases and other combustible rising from the fuel bed in the combustion space, after a sufficient quantity of air has been added. The results of the study are given in this report."

Gas-Cooled Reactor Project Quarterly Progress Report: June 1960

Description: Report documenting ongoing research and developments at the Oak Ridge National Laboratory's Gas-Cooled Reactor Project. Design Investigations: The effects on the power distribuestablished. A mathematical model was developed for studying shifting of the coolant stream as it moves along a rod in order to predict the temperatures of the parallel streams as they progress through the reactor. A fuelelement life code developed for computing the internal temperature structure, the amount of fission gas released, the internal pressure, the cladding strain when the internal pressure exceeds the coolant pressure, and the creep damage was used for comparing top-loading and inventedloading fuel programs for the EGCR. A statistical method was developed for estimating the probability that the hot spot on the EGCR fuel element will exceed a given temperature. A method of cooling the EGCR control rods was developed that will minimize diversion of coolant flow through leakage paths between graphite blocks. A preliminary design of a control rod cooled by this method was developed. Means for reducing the thermal stresses in the top head nozzles of the EGCR pressure vessel were studied. The stresses in the graphite sleeves of the EGCR fuel elements were calculated, and the maximum stress was found to be within the allowable limit. A study was made of the thermal stresses in the EGCR pressure-vessel support skirt, and a satisfactory design was developed. Procedures for removing ruthenium and cerium contamination from steel were outlined and incorporated in procedures for decontaminating the EGCR charge and service machines. Experimental information was obtained on the thermal characteristics of the specified EGCR fuel cluster. The effect of relative orientation of adjacent clusters on the heattransfer distribution in the downstream element was studied by means of mass-removal measurements on naphthalene-coated reds. Velocity distributions in the downstream element of two adjacent EGCR-type clusters ...

Electric Brass Furnace Practice

Description: Report discussing 1) the pertinent information available on what electric furnaces can do to assist prospective users in selecting a furnace that fits their requirements and 2) the gradual evolution of the present commercial types of electric furnaces. Also discusses some of the fundamental principles in the design, construction, and operation of electric furnaces.

The Smokeless Combustion of Coal in Boiler Furnaces

Description: From Introduction: "The present bulletin not only shows that bituminous coals high in volatile matter can be burned without smoke, but also that large plants carrying loads that fluctuate widely, where boilers over banked fires forced to the capacity of their units, can be operated without producing smoke that is objectionable."
