A fuel burning power plant comprises a bed vessel with a bottom grate which divides the bed vessel into an upper combustion chamber and a lower part with at least one ash chamber. The bed grate consists of parallel air distribution tubes each with air nozzles, between which tubes gaps are provided where bed material may pass from the combustion chamber down to the ash chamber. Below the tubes there is a transverse air distribution chamber. The tubes are connected in groups to the air distribution chamber by a double-walled sleeve extending down from the tubes.
