摘要： An exhaust discharge system is disclosed. The exhaust discharge system comprises an exhaust stack including a first conduit and a second conduit. The first conduit defines a first flow passageway and arranged around a first longitudinal axis. The first conduit including a skirt portion and a body portion disposed downstream of the skirt portion, and the skirt portion is oriented to slope outward from the body portion. The second conduit is disposed downstream of the first conduit. The second conduit defines a second flow passageway and is arranged around a second longitudinal axis, the second conduit includes a sidewall and an exit port, the exit port having an exit-port cross-section, wherein the exit-port cross-section is oblong in shape. The second longitudinal axis is disposed at an intersection angle to the first longitudinal axis, the intersection angle in a range of 125° to 150°. The exhaust stack is configured to convey treated exhaust from the skirt portion to the exit port.
