Combustion Chamber Supply Device and Method Thereof

A supply tube assembly for supplying solid particles to a combustion chamber, said supply tube assembly having a central longitudinal axis, a first end and a second end, the supply tube assembly comprising:

• a supply pipe extending in parallel with the central longitudinal axis from the second end of the supply tube assembly to the first end of the supply tube assembly, the supply pipe being open to form a pipe outlet from said supply pipe at the first end of the supply tube assembly, the supply pipe being configured for transporting solid particles carried by a fluid from the second end of the supply tube assembly to the pipe outlet through said supply pipe;
• at least one inlet connector attached to the supply pipe at the second end of the supply tube assembly and configured to connect at least one supply line to the supply pipe for supplying the solid particles and the carrier fluid into the supply pipe;
• a ramp arranged inside the supply pipe at the pipe outlet and pivotably arranged such that the inclination of the ramp in relation to the central longitudinal axis is adjustable by pivoting the ramp about a pivot axis which is perpendicular to the central longitudinal axis, the ramp extending from said pivot axis towards the pipe outlet;
• and
• adjusting means attached to the ramp for adjusting the inclination of the ramp and for holding the ramp at said inclination.
