A process for regulating the combustion of solid fuels in a combustion plant is characterized in that the incompletely burned gases that are formed directly above the area of the combustion outlet are directed upward along the inner wall of the charge space, which runs between the charge space and the combustion chamber, and along the cover area of the charge space into the channels between the charge space outer wall and the furnace wall, as a down-draft, back to the fire bed. In a device for carrying out the process above the combustion outlet there is a cover that shields the opening of the combustion outlet against the passage of incompletely burned gases that form above the combustion outlet and/or within the cover area of the charge space there is a channel that connects the upper area of the charge space with the channel(s) that run between the charge space and the furnace wall and which introduces the incompletely burned gases that form above the combustion outlet into the down-draft of the mixture of air and incompletely burned gases in the channel(s), when if necessary the charge space cover channel provided in the cover area of the charge space is connected to a fresh air feed and/or if necessary the channel(s) between the charge space and the furnace wall is connected to a fresh air feed.
