1. A coking facility exhaust system, comprising:
an emergency stack having a length, an upstream portion, and a terminal end that is selectively openable;
a crossover duct extending laterally from a side of the emergency stack at an intersection of the emergency stack and crossover duct, such that the length of the emergency stack extends beyond the crossover duct; and
a contoured duct liner, including a convex surface operative to modify the direction of gas flow proximate the intersection of the emergency stack and crossover duct; wherein the convex surface of the contoured duct liner is operatively coupled with, and spaced from, a non-convex shaped surface of the exhaust system, such that the contoured duct liner is provided with a non-uniform thickness along a length of the contoured duct liner and a fluid flow passing the contoured duct liner passes over the convex surface of the contoured duct liner and is prevented from passing beneath the convex surface of the contoured duct liner, between the convex surface of the contoured duct liner and the non-convex shaped surface of the exhaust system to which the convex surface of the contoured duct liner is coupled.
