• JFE Steel Corporation

JFE Steel Corporation began operating a second battery in the No.6 coke oven of the company’s West Japan Works (Kurashiki) on December 15, 2010.

The battery (Battery B), which cost about 20 billion yen to build in roughly two years, is part of a domestic expansion under which JFE Steel is raising its annual crude-steel production capacity to 33 million tons.

The facility employs a special reduced-impact technology—a low nitrous oxide combustion system developed by SCOPE 21 (Super Coke Oven for Productivity and Environmental Enhancement toward the 21^st Century), a project funded through the government’s Coal Production and Utilization Technology Promotion Program. JFE Steel previously adapted the technology for its Fukuyama No. 5 coke oven (Battery D).
