Firing an Iron Ore Pelletizing Kiln With Low-btu Gas from Lignite.
MISSING :22 pages
This Bureau of Mines report summarizes the performance characteristics of a 30-day around-the-clock gasification- pelletizing test conducted in October and November of 1980 with North Dakota Indianhead lignite. Gasification was conducted in a commercial-size, 6.5-Ft-diam, single-stage, fixed-bed, atmospheric pressure producer with a rated capacity of about 30 million btu/hr. Iron oxide pellets made from a commercial hematite concentrate were fird with the low-btu gas in a 2.8-Ft-diam by 35-ft-long pilot plant rotary kiln at a rate of 900 lb of pellets per hour. Gasifier operations at fuel feed rates up to 3 tons of lignite per hour and hematite pellet induration with raw 160-btu/std ft3 lignite gas are described.
