Title:
METHOD AND SYSTEM FOR MONITORING THE MASS CHANGES OF HEAT EXCHANGERS OF A STEAM BOILER
Document Type and Number:
WIPO Patent Application WO/2014/199016
Kind Code:
A3
Abstract:
A method and a system for monitoring the mass changes of a heat exchanger bank (10, 11, 12) of a steam boiler. The heat exchanger bank (10, 11, 12) is supported by hanger rods (13) and support beams (14) to the frame beams (15) of the steam boiler. In the method, the web plates (22) of the support beams (14) are provided with strain gages (17) for measuring the changes in the strain state generated in the support beams (14) by the mass of the heat exchanger bank (10, 11, 12). The system comprises a number of strain gages (17) fixed to the web plates (22) of the support beams (14), for measuring the changes in the strain state generated in the support beam (14) by the mass of the heat exchanger- bank (10, 11, 12), data logging means for logging the measurement data and a computer or a corresponding calculation unit for processing the measurement data.
