Abstract

In a combustion or gasification plant having a chamber (4) the mixing conditions or ratio are controlled via a fluid supplied by perforated tubes (13) to maintain a combustion or gasification process. To have an effect on the mixing of the fluid in the combustion gases the tubes (13) are displaced axially in mutual cooperation at longer or shorter time intervals in the chamber. Then the flue gas or gas parameters of the process can be optimized. Further, the tubes are rotatable around their axis and may for replacement purpose be completely withdrawable from the chamber. The tubes are cleaned in connection with their withdrawal. Object of protection are also a feeding means for use in a combustion or gasification plant of the mentioned type.
