Abstract

A combustor triple liner assembly includes coaxially aligned and radially spaced cylindrical inner, middle and outer liners forming an inner annular flow-path between the inner and the middle liners, and an outer annular flow-path between the middle and the outer liners. A plurality of inner dividers segments the inner annular flow-path into inner compartments. A plurality of outer dividers segments the outer annular flow-path into outer compartments and the middle liner into middle liner sections corresponding to each outer compartment. Each middle liner section includes a plurality of impingement holes fluidly connecting the outer compartment to one corresponding inner compartment which in turn is fluidly connected to one corresponding downstream outer compartment through an opening in the middle liner, such that cooling air flows from the outer compartment through the impingement holes into the corresponding inner compartment and therefrom through the opening into the corresponding downstream outer compartment.
