摘要： A direct reduction process for producing direct reduced iron (DRI) in a reduction reactor having a reduction zone for reducing iron-oxides-containing particles, such as iron ore pellets, to DRI by reaction of said iron oxides with a high temperature reducing gas, and a cooling zone for lowering the temperature of the DRI produced in said reduction zone, wherein a stream of cooling gas, usually natural gas, is circulated through said cooling zone, a portion of said cooling gas is withdrawn from the cooling zone, cooled and cleaned in a gas cooler and a portion of the cooled gas is recycled to said reduction zone by means of an ejector utilizing the high-pressure natural gas make-up feed as the ejector's motive fluid. Using an ejector for recycling the cooling gas instead of using a mechanical compressor provides significant savings in electricity and in capital, operational and maintenance costs. A direct reduction plant having a DRI cooling zone which uses at least one ejector in recycling at least a portion of cooling gas to the cooling zone.

摘要： A method and apparatus including a reduction reactor (10) for producing DRI, prereduced materials utilized in the steelmaking industry, where hydrogen contained in the gas stream purged from the reduction reactor (10) is separated (preferably by means of a PSA system) (52) and recycled to said reduction reactor (10). The productivity of the reduction plant is increased by using the separated hydrogen as a chemical reductant in the reactor (10), instead of using it as fuel. This is particularly useful in upgrading existing DRI production methods.
