How is a turbo blower used for a blast furnace in a steel plant?

Turbo blower is used for supplying hot air to provide the necessary oxygen to burner for burning.

In a blast furnace, fuel (coke), ores, and flux (limestone) are continuously supplied through the top of the furnace, while a hot blast of air (sometimes with oxygen enrichment) is blown into the lower section of the furnace through a series of pipes, so that the chemical reactions take place throughout the furnace as the material falls downward.
