Simultaneous removal of aqueous Zn2+, Cu2+, Cd2+, and Pb2+ by zeolites synthesized from low-calcium and high-calcium fly ash
In this study, zeolites were synthesized from low-calcium (LCZ) and high-calcium (HCZ) fly ash, respectively. Subsequently, the zeolites were tested for their removal effectiveness for four aqueous cations, namely, Zn2+, Cu2+, Cd2+, and Pb2+, as a function of contact time, pH value, adsorbent dosage, and initial concentration of heavy metals. Both zeolites were characterized by X-ray ...

Fly Ash & the Lightweight Aggregate Market
In 2015, the global fly ash market was estimated to be valued at 40 billion USD. A recent industry analysis by Research Nester anticipates the market will reach an estimated 70 billion USD by the end of 2023 – a 7.1% CAGR owing to increasing urbanization and a boost in construction projects. Along with bottom ash (BA) and flue gas desulfurization gypsum (FGD gypsum, or synthetic gypsum), ...

Laboratory investigation of hydraulic characteristics of fly ash as a fill material from the aspects of pollutant transport
Depending on the usage of fly ash, it is necessary to determine its environmental parameters, such as the potential for pollutant transport/leaching after its built-in. This study presents a methodology for determination of transport parameters (filtration coefficient, effective porosity, longitudinal dispersivity, and the mean residence time) from experimental data collected from column ...

Why is Energy-from-Waste slow to catch on in the U.S.?
Nithin Coca reports in TriplePundit that Energy-from-Waste (EfW) is growing fast in Europe and parts of Asia. But it’s relatively stagnant here in the United States. In fact, the percentage of waste we burn for energy is actually slightly down in the past five years. What’s holding the U.S. back from this potentially sustainable solution? This stagnation is even more surprising when ...

Cenospheres - Case Study
The problem: A cenosphere is a lightweight, inert, hollow sphere made largely of silica and alumina and filled with air or inert gas, typically produced as a byproduct of coal combustion at thermal power plants. On average 0.5% of the fly ash generated in a coal fired power station boiler are Cenospheres. When fly ash is wet discharged in to ash ponds/lagoons cenospheres float on the water ...

Why Are CHP Closing All Over The World?
Burning of coal nowadays has become a big problem. The main reason for this is a rapid increase of mankind. So, China burns half of coal in the world. Since 2000 the share of coal in world energy production has increased from 25 to 30%, and the Chinese economy is responsible for 82% of this growth. In Beijing, it is customary to use individual heat sources such as electric heaters and the like. ...

UK Abattoir – Rotary incinerator - Case Study
Designed to process animal remains 24 hours/day, 7 days/week, with the minimum of operator attendance. To optimise the plant’s performance and to enable waste to be processed and stored, irrespective of the status of the combustion plant, the waste is crushed into 50mm cubes. The material is then conveyed into a buffer hopper, which stores sufficient material to enable the plant to be left ...

Vattenfall`s Cogeneration Power Plant Reuter West - Case Study
The cogeneration power plant “Reuter West” was erected as a base load power plant in the vicinity of the existing “Reuter” plant. The two hard coal fired 300 MW units D and E were commissioned in 1987 and 1989. Today the cogeneration units supplying electricity and thermal energy are operated by Vattenfall Europe GmbH. The heart of each power plant is the boiler where the ...

Fly Ash Treatment – Plasma Torches versus Graphite Electrodes
Background Plasma generating devices have to be designed to tolerate incredibly harsh conditions during operation and in particular very high heat loads and temperatures around the arc. However, when used in the vitrification of highly chlorinated materials the challenge is even greater than in other applications. The combination of high general furnace temperatures, extremely high local ...

Spatial differences in trace element bioaccumulation in turtles exposed to a partially remediated coal fly‐ash spill
Large‐scale releases of environmental contaminants from industrial facilities can cause considerable damage to surrounding ecosystems and require remediation. The expense and/or undesirable environmental side effects of physical removal may constrain remediation efforts. In 2008, approximately 4.1 million cubic meters of fly‐ash were released into the Emory River at a coal burning power plant ...

Case study - Fly ash concrete design for Chicago’s 100-year road structure
After years of heavy use, Wacker Drive, a major two-level viaduct in downtown Chicago, Illinois needed to be rebuilt. The Chicago Department of Transportation (CDOT) set ambitious goals for the $200 million concrete structure because of its central location and importance to downtown traffic flow. The end result is a more durable roadway with a service life of 75 to 100 years. Originally built ...
