ABSTRACT:
A steam generator has a continuous heating surface located in a fuel gas channel that can be traversed in an approximately horizontal fuel gas directions. The continuous heating surface has a plurality of steam generator pipes that are connected in parallel for the passage of a flow medium and is designed in such a way that a steam generator pipe, which is heated to a greater extent than another steam generator pipe of the same continuous heating surface, has a higher throughput of the flow medium than the other steam generator pipe. The aim is to produce a low-cost steam generator with a particularly high level of mechanical stability, even when subjected to different thermal stresses. To achieve this, the or each steam generator pipe has a respective downpipe section, which is approximately vertical and through which the flow medium can flow downwards and a respective riser pipe section connected downstream of the downpipe on the flow medium side, which is approximately vertical and through which the flow medium can flow upwards.
