This study evaluates the behaviour of total Cr and Cr (VI) during coal combustion in two Spanish power stations. The content and distribution of Cr in the feed coal and combustion wastes was determined and the Cr contents were normalized using enrichment factor indexes. The speciation of Cr in the fly ash fractions from the different hoppers of the electrostatic precipitators was established an...

Introduction Semi-volatile organic compounds (SOCs), including polychlorinated dibenzo-p-dioxins/ dibenzofurans (PCDDs/Fs), are partitioned as gas-phase and particle-bound products of many industrial combustion processes. This gas/particle partitioning of SOCs has severe implications on both monitoring and control technologies. While particle-bound PCDDs/Fs are largely controlled by particulate...

Landscape fires can produce large quantities of smoke that degrade air quality in both remote and urban communities. Smoke from these fires is a complex mixture of fine particulate matter and gases, exposure to which is associated with increased respiratory and cardiovascular morbidity and mortality. The public health response to short-lived smoke events typically advises people to remain indoo...

The paper focuses on two particular phenomena which contribute to the poor collection efficiency of fine particles (from ~ 0.1 μm to ~ 2 μm) by electrostatic precipitators (ESPs). Firstly, the influence of turbulence on collection rate is considered as well as the fact that the charged fine particles are expected to give the main contribution in the generation of small eddies in ESPs. Experimen...

Pulverized coal boilers, commonly used in the power and heat-generating industries, constitute one of the most important sources of fine particulate matter (PM) emitted to ambient air. The evidence on airborne PM and its public health impact is consistent in showing adverse health effects at exposures currently experienced by urban populations in both developed and developing countries [1]. The...

The paper focuses on two particular phenomena which contribute to the poor collection efficiency of fine particles (from ~ 0.1 μm to ~ 2 μm) by electrostatic precipitators (ESPs). After considerations on the influence of turbulence which tends to decrease the collection rate, a conjecture is recalled on the action of the charged fine particles which is expected to give the main contribution in ...

In addition to public health measures, including social distancing, masking, cleaning, surface disinfection, etc., ventilation and air filtration can be a key component of multi-pronged risk mitigation strategy against COVID-19 transmission indoors. Electrostatic precipitators (ESP) have already proved their high performance in fluid filtration, particularly industrial applications, control exh...

Biomass is commonly used for heat production in small-scale and domestic facilities. Particulate matter (PM) emissions from the combustion of solid biomass are a concern because hazards to human health. Electrostatic precipitators (ESPs) have been supported as most promising mitigation technology, although there lack consolidation provide promulgate solution. The currently published studies on ...

The production of cement increases every year, which leads to the emission dust/gas/ particulate matter. unfiltered dust would create a significant environmental impact. Hence, it is responsibility industries control dust. Air filters and electrostatic precipitators (ESP) play role in controlling pollutants. Synthetic filter media are dangerous our environment widely used most industries. dispo...
