A condition report from Medway power plant in Kent, England showed that the Veotec trace heated air intake system is performing brilliantly.  Set to automatic and requiring no maintenance, the system has prevented snow and ice build-up despite the recent treacherous conditions at the plant.

The system was originally installed over four years ago. Due to its coastal location the Medway site was suffering from two distinct issues within their Gas Turbine both of which were causing loss of power from the gas turbine as well as the requirement for 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 occurrence of freezing fog. This caused a steep rise in pressure drop across the existing filter system and moisture carry over into the system.

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.

In its first year of operation on the first of two turbines it proved to give a significant advantage in power loss. Therefore, the decision was taken to install the system on the second turbine.
