Method for increasing the penetration depth of an oxygen stream

摘要

A method and device are disclosed for automatically evaluating a delivery system in respect of the energy efficiency and emissions efficiency thereof. The method may include: determining a service level for the delivery system according to an energy intensity and an evaluation relevance of the particular delivery system, detecting energy data and emissions data of the delivery system corresponding to the determined service level of the delivery system, and calculating at least one indicator based on the detected energy data and emissions data and/or based on data for the energy management and environmental management of the delivery system for evaluating the delivery system with respect to the energy efficiency and emissions efficiency thereof.

1. A method for increasing a penetration depth of an oxygen stream of technically pure oxygen entering with a volume flow and a mass flow and with a flow speed through at least one oxygen nozzle into the bed of an iron ore production unit for gasification of carbon carriers present in the bed, the method comprising:
increasing the volume flow of the oxygen stream while the mass flow of the oxygen stream remains constant by increasing the diameter of the at least one oxygen nozzle, and increasing a temperature of the oxygen stream while the flow speed remains constant.
