ABSTRACT Heat‐balance determinations were conducted on a number of sewerpipe kilns and the kiln efficiencies were found to vary from 14.97% to 29.03%. The method of calculating the heat balance is described in detail. Kiln efficiencies for individual periods range higher for the second period in most cases with some of the kilns reaching upward of 40% efficiency. In general as the kiln reaches higher temperatures the kiln efficiency decreases due to increasing stack and kiln structure losses. In all, thirty‐four kiln tests were conducted in six plants in various sections of the country, in twenty‐six of which heat‐balance calculations were made, the remainder being auxiliary tests giving only general operating data such as tonnage of ware, fuel consumption, temperature schedule, and ware analysis.
