Title:
IMPROVEMENTS IN AND RELATING TO STEAM WASTAGE MEASUREMENT AND MANAGEMENT
Document Type and Number:
WIPO Patent Application WO/2009/127879
Kind Code:
A3
Abstract:
An apparatus for detecting leakage of steam within a steam operating system, the apparatus comprising detection means (4, 6) operable to detect vibrational signals from a region of a steam operating system (1) such as a steam trap (2, 3), indicative of steam leakage, and comparison means (5) for comparing the vibrational signals detected by the detection means in the region to vibrational signals previously measured or calculated indicative of leakage of steam from a control region indicative of a known quantity of steam leakage, to thereafter indicate an actual or calculated quantity of steam leakage at the region being tested without reference to temperature or pressure of the steam. The method includes the steps of measuring or calculating a plurality of said vibrational signals, storing the indicative signals for subsequent access, measuring or calculating actual vibrational signals indicative of steam leakage, comparing the signals obtained with the corresponding stored signals, and calculating actual steam loss without reference to temperature or pressure of the steam.
