Method and system for controlling a filter
According to the method for controlling a filter ( 3 ) for an air intake duct of a turbine: the filter ( 3 ) is exposed to an incident flow of sprayed salt water; and parameters of the flow on either side of the filter, which are representative of the salt retention capability of the filter, are measured.
1. A method for monitoring a filter for an air intake duct of a turbine, the method comprising the steps of:
subjecting the filter to an incident flow of sprayed salt water; and
measuring parameters of the flow on either side of the filter, representative of a salt retention capability of the filter,
wherein the measuring step is performed in a test sequence of at least one monitoring test in which measurement members are moved in a test duct in which the filter is placed, and
wherein each test comprises measurement of a salt concentration, a number of salt water droplets, and a quantity of water.
2. The method of claim 1 , in which three fifteen minute tests are performed, at twenty minute intervals.
3. The method of claim 1 , in which four test sequences are performed.
4. The method of claim 3 , in which the filter is dried between the test sequences.
5. The method of claim 1 , wherein the filter is inclined by ten degrees relative to the horizontal axis.
6. The method of claim 1 , wherein the filter is a dry filter charged with dust.
7. The method of claim 6 , wherein the test sequence is performed on the dry filter charged with dust.
8. The method as claimed in claim 7 , wherein the salt retention capability of the filter is measured.
9. A system for monitoring a filter for an air intake duct in a turbine comprising:
a means for injecting a flow of sprayed salt water toward the filter; and
measurement members arranged on either side of the filter for measuring parameters of the flow, representative of a salt retention capability of the filter,
wherein the measurement members are configured to be moved in a test duct in which the filter is placed for at least one monitoring test, and
wherein each test comprises measurement of a salt concentration, a number of salt water droplets, and a quantity of water.
10. The monitoring system of claim 9 , wherein the measurement members comprise at least one measurement member selected from the group consisting of: a flow meter, a conductivity meter, a photometer, a white light spectrometer, a humidity sensor, a pressure sensor and a particle measurement device.
