摘要

The paper deals with our working experience in reducing the level of noise from seven air intakes of forced-draft fans of power and hot water boilers, under the conditions of restrictions observed at existing power plants. It is demonstrated that the desired reduction in the noise level may be attained under conditions of moderate aerodynamic drag and without remodeling the existing channels of air intakes of different configurations.
