APPARATUS FOR DETERMINING DRYNESS, ENTHALPY, THERMAL AND MASS FLOW OF WET STEAM

摘要

FIELD: physics.;SUBSTANCE: invention relates to applied physics and can be used to determine parameters of wet steam. Disclosed is an apparatus for determining dryness, enthalpy, thermal and mass flow of wet steam, having a steam pipe with a static pressure measuring device and two flow parameter measuring devices, one of which is selective to vapour phase parameters of a stream, e.g. downstream a Pitot tube, and the other is selective to vapour and liquid parameters of a stream, e.g. opposite the stream from a Pitot tube, a controller for processing and storing signals from the measuring devices with connected outputs of the measuring devices, a flow energiser, as well as a constant stream cross-section area downstream the flow energiser, having receivers of all measuring devices. The apparatus further includes a steam sampling unit and a module for determining reference dryness values connected to the steam sampling unit and the controller.;EFFECT: high accuracy of determining parameters of wet steam.;1 dwg
