A method for smoothing the gas flow profile in a duct or pipe in a system wherein the average gas velocity is greater than ten feet per second, comprising positioning within the duct or pipe and across the gas flow, a perforated plate wherein the openings thereof are hexagonal in shape, enabling the use of smaller holes than would otherwise be achievable with the use of round holes for the same pressure drop across the plate, which results in a higher degree of gas velocity profile smoothing for a given pressure drop across the plate.
