Abstract
Official abstract text for this publication.
A forced-flow steam generator includes first and second steam generator pipes which form a surrounding wall, wherein the first and second steam generator pipes are welded in a gas-tight fashion and are traversable by flow in a vertical direction. A passage collector is arranged within the surrounding wall, wherein the passage collector connects the first steam generator pipes with the second steam generator pipes. The first steam generator pipes are connected at an outlet side to an inlet side of the second steam generator pipes, wherein the second steam generator pipes are connected in series with the first steam generator pipes. Each of the second generator pipes has a restrictor device. Further, a power plant with a forced-flow steam generator is provided.
First claim
Opening claim text (preview).
The invention claimed is: 1. A forced-flow steam generator, comprising: first and second steam generator pipes which form a surrounding wall, wherein the first and second steam generator pipes are welded in a gas-tight fashion and are traversable by flow in a vertical direction, a passage collector arranged within the surrounding wall, wherein the passage collector connects the first steam generator pipes with the second steam generator pipes, wherein the first steam generator pipes are connected at an outlet side to an inlet side of the second steam generator pipes, wherein the second steam generator pipes are connected in series with the first steam generator pipes, and wherein the second generator pipes each have a restrictor device, wherein each restrictor device is arranged at an upper outlet of the surrounding wall, and wherein each restrictor device is designed as an aperture including a smaller diameter than the second generator pipe. 2. The forced-flow steam generator as claimed in claim 1 , wherein the first steam generator pipes are connected to each other in parallel, wherein the second steam generator pipes are connected to each other in parallel, and wherein the first steam generator pipes are connected in series with the second steam generator pipes. 3. The forced-flow steam generator as claimed in claim 1 , wherein the surrounding wall has an essentially rectangular horizontal cross-section. 4. The forced-flow steam generator as claimed in claim 1 , wherein the passage collector is arranged horizontally and circumferentially around the surrounding wall, wherein the first steam generator pipes are arranged below the passage collector in the surrounding wall, and wherein the second steam generator pipes are arranged above the passage collector in the surrounding wall. 5. The forced-flow steam generator as claimed in claim 4 , wherein the steam generator pipes upstream of the passage collector are arranged in a spiral shape circumferentially in the surrounding wall. 6. The forced-flow steam generator as claimed in claim 1 , further comprising: a combustion chamber with a plurality of burners for fossil fuel. 7. The forced-flow steam generator as claimed in claim 1 , further comprising: a steam turbine arranged downstream at a flow medium side. 8. A power plant, comprising: a forced-flow steam generator as claimed in claim 1 .
