Abstract:
A module for the testing of the effect of NO.sub.x control processes on actual expanded surfaces which are being considered for operational positioning within a primary flue gas stream, intermediate an exhaust gas source and the outlet of an exhaust gas stack therefor, and wherein the module is adapted to be inserted within the primary duct for such a primary flue gas stream, comprising:a body assembly having upstream and downstream axially spaced open ends thereof;an expanded surface test insert within said body assembly, which test insert is sized and configured to replicate the structure of such actual expanded surfaces being considered;flow enhancement means in cooperation with the body assembly; andsaid flow enhancement means being operable to establish a velocity of the gas stream passing through the test insert, which will replicate an operational velocity of the gas stream passing through the actual expanded surfaces, which operational velocity falls within a range between a selected minimum velocity occurring at fractional source loads, and a selected maximum velocity.
