Problem

Due to its coastal location Medway were suffering from two distinct problems within their gas turbines, both of which were causing loss of power from the gas turbine and increased compressor washes to maintain optimum performance.

The first problem was moisture laden air coming from the sea thus it was corrosive in nature.

The second problem was the occurrences of freezing fog. This caused a steep rise in pressure drops across the existing filter systems and moisture carry over into the system.

Solution

Veotec designed and manufactured a new two stage filter protection system. The main purpose of this was to protect the final H10 filters from moisture carry over. The second aim was to protect the turbine and compressor from the salt laden air.

The new system comprises a trace heated marine vane separator with a G4 panel filter.

Results

Since installation Kent has probably had one of its worst winters in a long time with considerable snow and long periods of time where the temperature was well below freezing. Despite these harsh conditions, the filter house performed normally with no adverse conditions due to the extreme weather.

The site has two engines so direct comparison between the modified engine and the existing installation was possible and, as can be seen from the graph below, there were distinct advantages to the new system in terms of power loss.
