Abstract
A process for producing cooling gas for a producer gas produced in a melt-down gasifier and surplus gas usable in an appropriate manner by cooling and cleaning at least part of the producer gas and the top gas of an iron ore reduction unit are proposed. The cooling gas is exclusively obtained by preparing producer gas. There is a cooling and a cleaning unit for the surplus gas and the cooling gas in each case. A constant gas flow is passed through the rear portion of the cooling and cleaning unit for the cooling gas with the aid of a constant volume blower. That part of the producer gas supplied to the cooling and cleaning unit for the cooling gas which exceeds this constant gas flow is passed into the cooling and cleaning unit for the surplus gas.
