Abstract
A method and apparatus for mixing a first relatively cool gas current and a second relatively hot gas current in a manner such that the resulting gas current has a relatively uniform temperature immediately subsequent to the point of mixing. The first gas current is separated into first and second partial gas currents, the first partial gas current being directed to a conduit which branches from the conduit in which the second partial gas current is directed. The first partial gas current is directed at a relatively high velocity into a central nozzle in fluid communication with the second gas current while the second partial gas current is directed into a ring nozzle which also is in fluid communication with the second gas current and which concentrically surrounds the central nozzle. The flow of the first gas current is regulated by throttling the second partial gas current while maintaining the flow of the first partial gas current. The method and apparatus has particular application in the regulation of the inlet temperature to a heat exchanger of a cooling gas current in a dry cooling plant for hot bulk materials, such as coke.
