Method and apparatus for removing alkali metal contamination from gas turbine liquid fuels

摘要

A system for continuously removing alkali metal contaminants from liquid fuel supplied to a combustor of a gas turbine comprising a source of fuel; means for supplying the fuel to the gas turbine; a prefilter downstream of the source and upstream of the gas turbine for removing solid particulates from the liquid fuel; and a coalescer located downstream of the prefilter and upstream of the gas turbine for separating water containing alkali metals from the liquid fuel.
