A METHOD OF MINIMIZING DISRUPTION CAUSED BY DEPOSITIONS ON A SUPPLY MEANS FOR A COMBUSTION OR GASIFICATION PLANT AND SUCH A SUPPLY MEANS

摘要

In a method of minimizing disturbances caused by depositions on a feeding apparatus for a combustion or gasification plant, secondary air is fed via perforated tubes (13) which by affecting the emission levels of the process with longer or shorter time intervals are inserted and withdrawn from the chamber, respectively, while being cleaned from slag, dust and other deposits outside the chamber. The combustion process may continue by using the remaining tubes (13) while one or more thereof are cleaned. A feeding apparatus implementing said method is also described and claimed.
