Abstract
Stack ejectors are considered as an essential component in numerous industries, serving as a pivotal mechanism for efficiently eliminating flue gas by inducing a draft. This research delves into the intricacies of stack ejector design and performance, emphasizing evaluating the consequences of deviations in ejector nozzle angles on flue gas flow. Within the stack ejector system, an air fan propels air into the stack to encourage flue gas to exit. The correct design and alignment of the ejector nozzle are paramount in maximizing flue gas flow. The computational fluid dynamics (CFD) simulations were carried out to gauge the impact of deviations in the ejector nozzle angle on flue gas flow. The results revealed that the deviations of 2, 4, and 6 degrees in the ejector nozzle angle would reduce the flue gas flow by 25%, 50%, and 60%, respectively. These findings underscore the substantial influence of ejector nozzle variations on flue gas flow within the stack ejector system. By comprehending the ramifications of nozzle angle deviation, engineers can enhance the design and alignment of stack ejectors to elevate their performances and overall efficiencies within their industrial setups.
