Fly Ash Processing Equipment - FEECO

FEECO has been processing fly ash for over 65 years, providing custom, high-quality agglomeration and material handling equipment for de-dusting fly ash, and turning it into a more marketable product. Fly ash material solidifies while suspended in the exhaust gases and is collected by electrostatic precipitators or filter bags. Since the particles solidify rapidly while suspended in the exhaust gases, fly ash particles are generally spherical in shape and range in size from 0.5 µm to 300 µm. The major consequence of the rapid cooling is that few minerals have time to crystallize, and that mainly amorphous, quenched glass remains. Nevertheless, some refractory phases in the pulverized coal do not melt (entirely), and remain crystalline. In consequence, fly ash is a heterogeneous material. SiO2, Al2O3, Fe2O3 and occasionally CaO are the main chemical components present in fly ashes. The mineralogy of fly ashes is very diverse. The main phases encountered are a glass phase, together with quartz, mullite and the iron oxides hematite, magnetite and/or maghemite. Other phases often identified are cristobalite, anhydrite, free lime, periclase, calcite, sylvite, halite, portlandite, ruti See full list on en.wikipedia.org In the past, fly ash produced from coal combustion was simply entrained in flue gases and dispersed into the atmosphere. This created environmental and health concerns that prompted laws[where?] that have reduced fly ash emissions to less than 1% of ash produced. Worldwide, more than 65% of fly ash produced from coal power stations is disposed of in landfills and ash ponds. Ash that is stored or deposited outdoors can eventually leach toxic compounds into underground water aquifers. For this reason, much of the current debate around fly ash disposal revolves around creating specially lined landfills that prevent the chemical compounds from being leached into the ground water and local ecosystems. Since coal was the dominant energy source in the United States for many decades, power companies often located their coal plants nearby metropolitan areas. Compounding the environmental issues, the coal plants need significant amounts of water to operate their boilers, leading coal plants ( See full list on en.wikipedia.org There is no US governmental registration or labelling of fly ash utilization in the different sectors of the economy – industry, infrastructures and agriculture. Fly ash utilization survey data, acknowledged as incomplete, are published annually by the American Coal Ash Association. Coal ash uses include (approximately in order of decreasing importance): 1. Concreteproduction, as a substitute material for Portland cement, sand. 2. Corrosion control in RC structures Goyal, A., & Karade, S. R. (2020). Steel Corrosion and Control in Concrete Made with Seawater. Innovations in Corrosion and Materials Science (Formerly Recent Patents on Corrosion Science), 10(1), 58-67. 3. Fly-ash pellets which can replace normal aggregate in concrete mixture. 4. Embankmentsand other structural fills (usually for road construction) 5. Grout and Flowable fillproduction 6. Waste stabilization and solidification 7. Cement clinkerproduction – (as a substitute material for clay) 8. Mine reclamation 9. Stabili See full list on en.wikipedia.org Groundwater contamination Coal contains trace levels of trace elements (such as arsenic, barium, beryllium, boron, cadmium, chromium, thallium, selenium, molybdenum and mercury), many of which are highly toxic to humans and other life. Therefore, fly ash obtained after combustion of this coal contains enhanced concentrations of these elements and the potential of the ash to cause groundwater pollution is significant.In the USA there are documented cases of groundwater pollution that followed ash disposal or utilizatio Ecology The effect of fly ash on the environment can vary based on the thermal power plant where it is produced, as well as the proportion of fly ash to bottom ash in the waste product. This is due to the different chemical make-up of the coal based on the geology of the area the coal is found and the burning process of the coal in the power plant. When the coal is combusted, it creates an alkaline dust. This alkaline dust can have a pH ranging from 8 to as high as 12. Fly ash dust can be deposited o Spills of bulk storage Where fly ash is stored in bulk, it is usually stored wet rather than dry to minimize fugitive dust. The resulting impoundments (ponds) are typically large and stable for long periods, but any breach of their dams or bundingis rapid and on a massive scale. In December 2008, the collapse of an embankment at an impoundment for wet storage of fly ash at the Tennessee Valley Authority's Kingston Fossil Plant caused a major release of 5.4 million cubic yards of coal fly ash, damaging 3 homes and f See full list on en.wikipedia.org Crystalline silica and lime along with toxic chemicals represent exposure risks to human health and the environment. Fly ash contains crystalline silica which is known to cause lung disease, in particular silicosis, if inhaled. Crystalline silica is listed by the IARC and US National Toxicology Program as a known human carcinogen. Lime (CaO) reacts with water (H2O) to form calcium hydroxide [Ca(OH)2], giving fly ash a pH somewhere between 10 and 12, a medium to strong base. This can also cause lung damage if present in sufficient quantities. Material Safety Data Sheets recommend a number of safety precautions be taken when handling or working with fly ash.These include wearing protective goggles, respirators and disposable clothing and avoiding agitating the fly ash in order to minimize the amount which becomes airborne. The National Academy of Sciences noted in 2007 that "the presence of high contaminant levels in many CCR (coal combustion residue) leachatesmay create human health See full list on en.wikipedia.org United States Following the 2008 Kingston Fossil Plant coal fly ash slurry spill, EPA began developing regulations that would apply to all ash ponds nationwide. EPA published the CCR rule in 2015. Some of the provisions in the 2015 CCR regulation were challenged in litigation, and the United States Court of Appeals for the District of Columbia Circuitremanded certain portions of the regulation to EPA for further rulemaking. EPA published a proposed rule on August 14, 2019 that would use location-based crit India The Ministry of Environment, Forest and Climate Change of India first published a gazette notification in 1999 specifying use of fly ash and mandating a target date for all thermal power plants to comply by ensuring 100% utilisation. Subsequent amendments in 2003 and 2009 shifted the deadline for compliance to 2014. As reported by Central Electricity Authority, New Delhi, as of 2015, only 60% of fly ash produced was being utilised. This has resulted in the latest notification in 2015 which ha See full list on en.wikipedia.org Due to the ignition of coal deposits by the Siberian Traps during the Permian–Triassic extinction eventaround 252 million years ago, large amounts of char very similar to modern fly ash were released into the oceans, which is preserved in the geologic record in marine deposits located in the Canadian High Arctic. It has been hypothesised that the fly ash could have resulted in toxic environmental conditions.

Value in Waste: Fly Ash Reuse and Recovery Opportunities

For example, although not a reuse application, many companies have taken to conditioning fly ash prior to deposit into landfill; processing fly ash in a pugmill mixer with water or a binder can de-dust the material so it does not become windblown upon deposit. This agglomeration process may also help to make the sample more stable and less likely to leach toxic components into the surrounding environment.
