Abstract
Specific Installation.—Describes installation of Underwood System to six terra cotta kilns at plant Northwestern Terra Cotta Company. Conclusions from operating data.—(1) Raw producer gas can be successfully applied to periodic muffle kilns. (2) There is little or no direct fuel economy over direct firing. (3) There is no labor economy unless the installation be large enough to justify mechanical coal and ash handling devices. (4) When interest on investment, depreciation and all other pertinent factors are taken into account, it is not likely that any great economy would be affected on periodic kilns over direct fire methods. Advantages.—They are: (a) Somewhat better control of combustion gases and kiln temperatures. (c) Cleaner and more orderly kiln yard. (d) Abatement of smoke nuisance, particularly important in large cities.
