#CMT# #/CMT# The steam power plant comprises fluid-conducting components and an acoustic cavity resonator (40), which is attached to a wall (48) of a steam pipe (26) of the fluid-conducting components in the steam turbine housing of the steam-water circuit for damping acoustic vibrations. The resonator is designed as Helmholtz resonator. The connection of the resonator is carried out by a detachable flange connection (52). #CMT# : #/CMT# An independent claim is included for a method for connection of an acoustic resonant cavity, such as a Helmholtz resonator for damping acoustic vibrations in a wall of steam pipe of the fluid-conducting components of a steam power plant. #CMT#USE : #/CMT# Steam power plant for conversion of thermal energy into mechanical energy in a thermodynamic cycle, in which steam or water is circulated as working fluid in a steam-water circuit. #CMT#ADVANTAGE : #/CMT# The acoustic cavity resonator is attached to a wall of a steam pipe of the fluid-conducting components in the steam turbine housing of the steam-water circuit for damping acoustic vibrations, where the resonator is designed as Helmholtz resonator, and thus enables efficient control of unwanted acoustic vibrations in the steam power plant, and avoids operational interruption of the steam power plant, and also prevents pressure loss in the interior of the components of the steam power plant. #CMT#DESCRIPTION OF DRAWINGS : #/CMT# The drawing shows a sectional view of a steam power plant fluid-conducting component. 26 : Steam pipe 40 : Acoustic cavity resonator 46 : Through-hole 48 : Wall 52 : Flange connection. |
