Abstract

PURPOSE: To contemplate the effective utilization of wet heat of produced gas, by supplying air and steam from the tuyere of a shaft furnace contg. briqueeted coal charge therein, carrying out dry distillation to gasify coal, and recovering produced gas from the top and the belly of the furnace.
CONSTITUTION: Briquetted coal or lump coal, an iron source and limestone are charged into a dry distillation zone 1 located at the top of a shaft furnace. Hot air and steam are supplied throuth a tuyere to the gasification zone 2 of the furnace. Dry distillaion is carried out. Then produced gas is recovered from the top and the belly of the furnace and introduced into a conversion part 3 where tar and ammonia liquor are added to the produced gas to obtain converted gas, said tar and ammonia liquor being separated from the dry-distilled gas recovered in the zone 1. The converted gas is supplied to a reducing shaft furnace 4 to use it as a heat source for converting green pellet obtd. from an iron ore into reduced pellet.
