A low-cost mitigation system for ammonia removal from broiler house exhaust air.

ABSTRACT: Most chicken farms in China utilize chemical deodorants in conjunction with a screen positioned near the fan outlet at the end of the breeding house for deodorization. However, practical observations indicate that the placement of these screens can impact ventilation and animal growth, while the efficacy of chemical deodorants remains uncertain. In this study, we utilized computational fluid dynamics (CFD) simulations to model a broiler house and analyzed airflow patterns at varying screen distances to assess their effect on indoor ventilation. Additionally, we designed an environmental simulation chamber to evaluate chemical deodorants. Subsequently, we developed an economical and effective ammonia removal blocking system (ARBS). The CFD simulation results show that the simulated wind spe
