SAFETY DEVICE FOR A WASHING SYSTEM FOR LIQUID FUEL BURNERS IN GAS TURBINES

摘要

A safety device for a washing system for liquid fuel burners in gas turbines, in which these turbines are provided with separate injectors for the combustion of liquid fuel or gaseous fuel, wherein the washing system comes into use when gaseous fuel is used and comprises a feed pipe (28, 30) for washing gas, a manifold (14) from which liquid fuel is distributed to the burners, and a drainage pipe (26) in order to discharge deposits of liquid; on the feed pipe (28, 30) there is inserted a closed tank (20) in which there are provided apertures both for an intake pipe (28) and for an outlet pipe (30) for the washing gas, for the drainage pipe (26) and for at least two liquid level sensors (32, 34).
