Latest Patents

Yohannes Ghermay holds a patent for a "Method of selective combustor control for reduced emissions." This method involves operating an industrial gas turbine engine with multiple combustor cans arranged in an annular array. Each can features burner stages and a pilot burner arrangement that includes both a premix pilot burner and a diffusion pilot burner. The method allows for asymmetric combustion, where at least one can operates as a warm can with respective burner stages off, while the remaining cans function as hot cans with their burner stages on. By maintaining a constant fuel flow to the warm can's pilot burner arrangement, Ghermay's method enables the adjustment of fuel fractions within the warm can's pilot burner arrangement, thereby optimizing emissions control.
