Abstract

PURPOSE:To uniformly distribute fuel and increase its combustion time by blowing a solid fuel from the tuyeres of a blast furnace through its blast duct separated from the body of the blast furnace. CONSTITUTION:When a solid fuel is blown from the plural tuyeres of a blast furnace, it is blown through cool blast duct, hot blast duct, and annular duct, which are all separated from the body of the blast furnace. In this manner, the ratio of solid fuel injected from each tuyere can be made even and fuel combustion time can be increased.
