About Why Boldrocchi Products Industries Services & Retrofits Case Studies News Downloads Contact Dust Removal Our dust removal technologies surpass all global particle matter (PM) requirements. Our solutions can achieve practically zero emissions: 0.1 mg/Nm3 (0.06 gr/ft3) (WTE applications) and we also offer systems that reduce not only PM10 and PM2.5, but PM0.1 a.k.a. ultrafine particles. Indeed, we continue to invest in our R&D to remain ahead of legislation, ensuring that you’re covered for years to come. Our Products Fabric Filters Electrostatic Precipitators (ESPs) Nuisance Filters Dust Removal Scrubbers Ceramic Candle Filters Hybrid Filters Cyclones / Multi-Cyclones Combustion Chambers / Drop-Out Boxes WE OFFER CAPABILITIES TYPES Fabric Filters / Baghouses We can design and produce fabric filters (baghouses/bag filters) for any industry, any application and any process condition as we tailor-make each one. Our fabric filters offer 99.9% efficiency, blocking even the smallest particulate matter (PM) (micro-pollutants). READ ABOUT OUR FABRIC FILTER INSTALLATIONS WE OFFER CAPABILITIES RESEARCH Ceramic Candle Filters (High Temperature Filtration) Filtration using ceramic filters is a technology gaining increasing interest and Boldrocchi is one of the few companies in the world with experience implementing it. High temperature filtration provides optimal filtration efficiency while withstanding high operating temperatures and is particularly useful when looking to increase heat recovery and/or comply with stringent emission regulations. What’s more, the use of ceramic filters reduces OPEX as they require less energy, fewer cleaning cycles and reduced downtime while foregoing the need for cooling systems. READ ABOUT OUR EXPERIENCE WITH CERAMIC CANDLE FILTERS WE OFFER CAPABILITIES Dry Electrostatic Precipitators (ESPs) Electrostatic precipitators (ESPs) continue to be excellent devices to control particulate emissions in several industries, including fumes from electricity-generating utilities (coal- and oil-fired) and catalyst collection from fluidized bed catalytic cracker units in oil refineries to name just two. We have significant experience dealing with ESPs in the cement industry as well, most often to refurbish or retrofit existing ESPs. Boldrocchi can also convert ESPs: use the external casing and some parts but transform the system into a fabric filter or hybrid filter. Retrofit, upgrade and conversion solutions are all lower CAPEX solutions. READ ABOUT OUR ESP INSTALLATIONS WE OFFER CHARACTERISTICS Hybrid Filters Hybrid filters offer high efficacy in dust removal. Hybrid filters are both an electrostatic precipitator (ESP) and a fabric filter in one system. The dust is first collected by the ESP section, and by the time the gas goes into the fabric filter portion, dust is greatly reduced. READ ABOUT OUR EXPERIENCE WITH HYBRID FILTERS WE OFFER CHARACTERISTICS Nuisance Filters Many clients know they need dust suppression, but don’t know exactly what they need. Others have space constraints and need off-sizes or strange shapes. Boldrocchi’s air pollution control specialists are experts in studying your process parameters, dust suppression goals and space constraints – they’ll go on-site if they have to – to design a customized solution that will achieve (or surpass) objectives and offer reliability for years to come. READ ABOUT OUR NUISANCE FILTER INSTALLATIONS WE OFFER CHARACTERISTICS APPLICATIONS Cyclones & Multi-Cyclones Adding cyclones or multi-cyclones can be a cost-effective strategy. They use centrifugal action to separate suspended particulates and collect them in a hopper. Cyclones are particularly effective with particles of a certain size and density, able to reduce dust (by weight) by up to 95%, or more if using multi-cyclones. READ ABOUT OUR EXPERTISE WORLDWIDE WE OFFER APPLICATIONS CIRCULATING DRY SCRUBBERS Dust Removal Scrubbers There are numerous kinds of scrubbers and Boldrocchi offers most of them. In terms of dust removal, Boldrocchi offers a wet scrubber or “Venturi” scrubber that removes dust particles – this one for rather light applications. These wet scrubbers use only water with no reagent to remove particulate matter (PM). These devices are relatively small compared to our other dust removal solutions, at roughly two stories high. READ ABOUT OUR EXPERIENCE WITH APC WE OFFER Combustion Chambers / Drop-Out Boxes Combustion chambers (or “drop-out boxes”) are dust pre-separation devices that protect the more efficient filtration device (often a fabric filter) from possible abrasion and sparks, increasing the lifetime of the main filtration device. These combustion chambers are common to de-dust electric arc furnaces, for example, in the steel industry.
