Embodiment Construction

[0029] about image 3 , where with figure 1 and 2 The same elements as those in have the same reference numerals, and the steam turbine plant according to the invention comprises an inner turbine casing 5 resting on a plate 16 by means of two brackets 20, one of which is fastened to the front discharge end 12, While the other is fastened to the rear discharge end 13, the concept of front and rear is relative to the axis X. These brackets 20 , which can be compared to horizontal plates and protrude outwards from the inner turbine shroud 5 at both discharge ends 12 , 13 , are identical and are aligned with each other at the same height. The plate 16 has a flat upper surface 21 against which two brackets 20 rest.

[0030] In the remainder of the description, only one bracket 20 is considered for simplicity of reading, but it is understood that the description applies to the second bracket 20 as well. Likewise, the description focuses on only one connecting means, even if ther...

Abstract

Module for a steam turbine comprising a low-pressure module (1), comprising an internal turbine casing (5) able to accommodate at least one set of fixed vanes and a rotor (6) equipped with at least one set of blades, and a slab (16), the internal turbine casing (5) resting on the slab (16) via at least two bearers (20) secured to said internal turbine casing (5), the connection between said bearers (20) and the slab (16) being afforded by a plurality of mechanical connecting means. The main feature of a device for a steam turbine according to the invention is that the connecting means (23) each combine two functions, one of them preventing the internal turbine casing (5) from lifting in relation to the slab (6), and the other allowing said internal turbine casing (5) to slide on this slab (16).

Description

technical field [0001] The object of the invention is a steam turbine module. Background technique [0002] A steam turbine is a rotary machine used to convert thermal energy in steam into mechanical energy to drive an alternator, pump or any other rotary mechanical receiver. A steam turbine typically includes a high-pressure module, possibly a medium-pressure module, and at least one low-pressure module. The steam supplied by the steam generator is sent to the high pressure module and then to the medium and low pressure modules. The steam exhausted from the low pressure module is directed to a condenser usually located below the low pressure module. [0003] The low voltage module arrangement is described below. [0004] about figure 1 , which schematically shows a stand-alone structure according to the prior art in which a structural piece supports firstly a steam turbine and secondly a condenser, a low-pressure module 1 comprising a housing 2 considered to be an exhau...
