 Scope of report—This report summarizes the salient features of operations
in the coke industry in 1932. It covers only coke and byproducts made by
high-temperature carbonization of coal in beehive and byproduct ovens. It
is important to note that data for the output of byproduct plants operated
by city gas companies also are included. In recent years the adaptation of
byproduct ovens to the needs. of city-gas manufacture has led a number of
gas companies to install batteries of byproduct ovens to supplement or replace
their coal-gas or water-gas plants. For supplying gas to lesser cities small
byproduct ovens have been developed to meet local requirements. The method
of production in these plants, as well as the products, are similar to those
of the standard-size plants. From the standpoint of ownership and accounting,
these city installations are part of the gas-utility system, but from other
standpoints they are part of the byproduct coke industry and are therefore
covered in the statistics for that industry by the Bureau of Mines.
 Coke is also made by other processes not covered in this report. It is estimated
that approximately 1,200,000 tons of gas-house coke were made by high-temperature
carbonization of coal in types of equipment other than coke ovens, chiefly
horizontal retorts. Petroleum coke i~ ~ byproduct of petroleum refining;
