WIND BARRIERS AS A POSSIBLE SOLUTION TO PM10 EMISSIONS IN INDUSTRIAL PLANTS
Abstract
This paper refers on the outcomes of an experimental study developed in an industrial plant in the centre of Italy in which dust emission represents an important annoyance affecting the whole activity and so requiring to be managed in order to guarantee legal compliance but, above all, a safe workplace. This case study consists in the assessment of the efficacy of different reduction measures designed to avoid and, where not possible, to reduce dust emissions from stockpiles. According to a monitoring campaign based on field sampled data, these areas were identified as the most pollutant sources in the plant itself and many solutions were taken into consideration to reduce the emission due to wind erosion. Under these conditions wind fences represent a significant solution to be tested in addition to usual measures which are usually installed. In particular some simulations are performed in order to define the variation of wind velocity all around the stockpile and so to select and design the best solution and configuration to reduce the emission of fugitive dust from stockpiles when caused by wind erosion.
