Problems solved by technology

Especially in steam generators whose effluent ends join a common effluent header, the individual steam generator tubes are heated differently, causing steam flows with widely different steam parameters to converge, causing undesirable efficiency losses, especially Reduced efficiency of associated heating surfaces and reduced steam generation
In addition, adjacent steam generator tubes are heated differently, causing damage to steam generator tubes or headers, especially at their entry into an outflow header

Embodiment Construction

[0026] In all figures, the same parts are indicated by the same reference numerals.

[0027] According to FIG. 1 , FIG. 2 and FIG. 3 , the steam generator 1 in the form of a waste heat steam generator is connected downstream of a gas turbine, not shown in detail, on the exhaust gas side. The steam generator 1 has a housing 2 which forms a gas channel 3 for the exhaust gas flowing out of the gas turbine to flow approximately horizontally in the gas flow direction indicated by the arrow 4 . Some heating surfaces designed according to the straight-through principle are installed in the gas channel 3 , also called straight-through heating surfaces 8 , 10 . In the embodiment shown in FIG. 1 , FIG. 2 and FIG. 3 , two through-type heating surfaces 8 and 10 are shown respectively, and of course only one or more through-type heating surfaces may be provided.

[0028] According to FIGS. 1 , 2 and 3 , the two straight-through heating surfaces 8 , 10 respectively comprise a certain numbe...

Abstract

A steam generator (1) is suitable for a horizontal structure on the one hand and has the advantages of a straight-through steam generator on the other hand. For this reason, the steam generator (1) of the present invention is provided with at least one straight-through heating surface (8, 10) in a gas channel that allows the gas to flow in an approximately horizontal direction, and it consists of a certain number of The steam generator tubes (13, 14) arranged approximately vertically and parallel to the flow direction of the medium are composed of steam generator tubes (13, 14), which are designed to be connected with other steam generator tubes (13, 14 ) compared to a steam generator tube (13, 14) which is heated more has a larger medium flow rate than other steam generator tubes.

Description

technical field [0001] The present invention relates to a steam generator. Background technique [0002] In gas and steam turbine installations, the heat contained in the expanding working medium or the gas in the gas turbine is used to generate the steam required for the steam turbine. Heat transfer is done in a waste heat steam generator connected after the gas turbine. A certain number of heating surfaces are usually installed in the waste heat steam generator for preheating the water, generating steam and superheating the steam. The heating surface is connected to the water-steam circulation process of the steam turbine. This water-steam cycle usually comprises a plurality (eg three) of pressure stages, each having an evaporator heating surface. [0003] The steam generator connected to the gas turbine as waste heat steam generator on the high-temperature gas side has various design options, namely straight-through steam generator or circulating steam generator. In s...
