Abstract

The aim of the invention is to provide a suitable method for producing a continuous steam generator (1) that can operate at high steam pressures, sai d method being cost-effective and involving simple technology. This is achieve d by a number of pipe segments (18), which are produced from a material of a first material category, are designed to form the steam generator pipes (12) and are combined into a number of modules (17). Each module (17) is equipped with a respective adapter (19) at a number of connection points that are designed to connect an additional module (17), said adapter being produced from a material of a second category.

Claims (9)

1. Method for producing a continuous steam generator (1), having an enclosing wall (4) formed from steam generator pipes (12) welded together in a gas-tight fashion, a number of pipe segments (18) made from a material of a first material category and provided to form the steam generator pipes (12) being combined into a number of modules (17), each module (17) being provided respectively with an adapter (19) made from a material of a second material category at a number of connection points provided for connection to a further module (17).
2. Method according to claim 1, wherein the materials of the first material category have a higher Vickers hardness than the materials of the second material category.
3. Method according to claim 1 or 2, wherein the pipe segments (18) are combined into modules (17) such that each module (17) respectively forms a surface, out of which the respective adapters (19) curve such that the adapters (19) provided to connect two adjacent modules (17) can be welded together in a plane that is offset in respect of the respective surface.
4. Method according to one of claims 1 to 3, wherein adjacent steam generator pipes (12) are welded together in a gas-tight fashion via fins (14), with the fins (14) being made from a material of the second material category.
5. Continuous steam generator (1) with an enclosing wall (4) formed from steam generator pipes (12) welded together in a gas-tight fashion and connected in parallel to allow the passage of a fluid medium, wherein at least some of the steam generator pipes (12) are each formed from a number of pipe segments (18) connected one behind the other on the fluid medium side and made from a material of a first material category and with pipe segments (18) of a steam generator pipe (12) arranged one after the other in the direction of flow being connected together via an adapter unit (22) made from a material of a second material category.
6. Continuous steam generator (1) according to claim 5, with the materials of the first material category having a higher Vickers hardness than the materials of the second material category.
7. Continuous steam generator (1) according to claim 5 or 6, wherein a number of adapter units (22), each comprising a number of adapters (19) made from a material of the second material category, are arranged such that a weld seam applied to connect two adapters (19) of the same adapter unit (22) together is outside a wall surface provided by the pipe segments (18).
8. Continuous steam generator (1) according to one of claims to 7, the combustion chamber wall of which comprises vertical piping.
9. Continuous steam generator (1) according to one of claims 5 to 8, with adjacent steam generator pipes (12) being welded together in a gas-tight fashion via fins (14), the fins (14) being made from a material of a second material category.
