<p>With a device for feeding a fluid, such as a gas or a liquid, into a solid-conveying line, wherein the fluid is first passed into a ring space that surrounds the solid-conveying line, and from there into the solid-conveying line, conveying of coal in the form of dust or flue ash, for example, is to be undertaken in gasification systems, at elevated temperatures, at great output and great operational reliability. This is achieved in that the solid-conveying line is shorter, in the ring space for forming a ring gap, than the length of the ring space, wherein installations for producing a vortex flow of the fluid that is introduced are provided in the ring space.</p> |
