EPSILON - GAS TURBINE AIR FILTER MONITOR

Quantitative Measurement and Cross-Sectional Mapping of Gas Turbine Air Filter Performance and Gas Turbine Filter Banks, Compressor Washer Optimization
Epsilon, a gas turbine air filter monitor which provides quantitative measurement and cross-sectional mapping of gas turbine air filter performance. It will uniquely:
•    detect the passage of particulates across the total cross section of the monitored space
•    record every particle, down to sub-micron level, that passes through a gas turbine filter bank
•    map the distribution of the particles in the cross-sectional plane
•    identify trends in the number of particles passing through the gas turbine air filter bank
•    quantify the number of particles, at any one point of time and in aggregate over time
•    measure the performance of gas turbine air filters
APPLICATIONS
Epsilon can be used:
•    as a gas turbine filter monitor
•    for condition monitoring of gas turbine operations
•    as a dust filter monitor in clean rooms and
•    as a replacement for or supplement to gravimetric testing, particularly where a quantitative measurement of the number (as opposed to mass) of particulate present will provide a suitable measure
•    for quantitative measuirement of particulate presence in very large dusts (to 40 meters)

GAS TURBINE APPLICATIONS
The Epsilon gas turbine filter monitor can improve the efficiency of gas turbine operations in two ways:
•    By monitoring filter efficiency and reducing down-time for filter maintenance
•    By allowing optimized fan maintenance scheduling and increased effective capacity
Filter Efficiency
Gas turbines draw in their air through large filter banks, to minimize the amount of dust passing (or hitting) the turbine fans. The filter banks, which can be six storeys high, contain several thousand filters which operate at varying degrees of efficiency as their performance gradually deteriorates over time. As a consequence, all of the filters must be checked manually by the operator in the event of breakthrough or at the time of programmed maintenance.
With real-time profiling of the entire cross-section of the filter, both the rate of deterioration and its location can be monitored continuously. Early warning means down-time decisions can be made solely on the basis of process monitoring. If a decision to shut down is warranted, the specific location where repair or replacement is required will already be known, and the duration of down-time minimized.
Epsilon΄s ability to locate and focus on areas of deterioration creates the potential for huge savings in down-time.
Optimised Maintenance Scheduling
Over time, the passage of very fine particles of dust through the filter bank results in a build-up of particulate matter on the turbine fan, with a resulting gradual decline in operating efficiency. As the rate of build-up is related to the rate at which particulate matter passes through the filter bank, over time operators will be able to develop an understanding of the relationship between the turbine operating efficiency and the cumulative volume of dust which has managed to pass through the filter bank. By providing a proxy direct measure of the compressor fouling, Epsilon will permit identification of the point at which the opportunity cost of the “lost” capacity exceeds the costs of a shut-down for maintenance/blade wash.
