Measurement, modelling and optimisation of the acoustic impact of the biomass conveyor system used in the power generation industry

Purpose: The study aims to measure, model and reduce the acoustic impact of the conveyor belt system planned for one of the Polish power plants. The system is currently in the design stage, and its elements will introduce additional noise sources. Design/methodology/approach: The analysis includes an assessment of noise sources and the creation of an acoustic model for the current state of the conveyor system, followed by the preparation of an acoustic model for the designed system for transporting biomass and the calculation of noise emission levels in the environment from the Power Plant area. The study also includes proposals for the system optimisation dedicated to minimising the acoustic impact. Findings: The analyses carried out confirm that the need to minimise the acoustic impact on the environment of belt conveyors operating in power plants directly is of an individual nature and depends on the location of the layout of the conveyors in relation to the land use of adjacent areas and the permissible noise values for them. Practical implications: When designing new installations, it is necessary to consider not only the selection of acoustic parameters for the equipment and mitigation measures, but also the potential use of existing infrastructure located along the path of noise transmission for shielding purposes. Originality/value: The methodology used, both in measurement and optimisation, utilising virtual reality simulations, can be applied as a universal tool for reducing the noise emitted into the environment by conveyor belt systems operating under various conditions.
