Studies on coal flotation in flotation column using statistical technique
Flotation of Indian high ash coking coal fines to obtain clean coal has been reported earlier by many authors. Here an attempt has been made to systematically analyse factors influencing the flotation process using statistical design of experiments technique. Studies carried out in a 100 mm diameter column using factorial design to establish weightage of factors such as feed rate, air rate and ...

Environment impact from ash disposal of the thermal power plant 'Kosova A'
Mining activities impact on environment is as old as these activities themselves. It is estimated that thermal power plants in Kosova produce about 1.6 million tons of ash per year, and all ash produced is disposed as waste material. The main problems for environment pollution are the ash dumps containing more than 40 million tons of ash cover about 150 ha of land. The ash dumps sites of the ...

How can we use Biomass as an energy source?
Any Country which has Agriculture or Forestry waste available has big scope to use biomass as an energy source. We can use Biomass as fuel in its loose form but we can also bind them in solid fuel for more energy consumption. Any biomass like forestry waste, Agriculture waste or any other biomass waste can be recycled into solid biomass fuel/Bio coal/White coal/Briquette. What is Bio-Coal/White ...

Unpredictable volcanic ash plumes restrict air traffic
Volcano Alert Level: “Warning” and Aviation Color Code: “Red.” If a volcano reaches this status, there is a major eruption imminent or already underway, which poses a threat to the surrounding areas on the ground and in the air. Even with early monitoring systems in place for hundreds of volcanoes worldwide, the unpredictable nature of earthquakes, eruptions, lava flows ...

Rice Husk Carbonization Furnace To Build Energy
Throughout the world, rice is really a staple food which is very common in the diet of your huge area of the global population. But, when rice is harvested it leaves behind a great deal of waste. After extraction of the edible rice, one of the leading waste products of rice is rice husks. Previously, rice husks were discarded to landfills since there was not one other valuable use on their ...

Case study - Fly ash for California’s Olivenhain dam
The Olivenhain Dam will be the first roller compacted concrete (RCC) gravity dam in California and the tallest in North America. At 308 feet tall and 2,552 feet long, the dam used almost 1.5 million cubic yards of RCC and over 152,000 tons of fly ash. As the centerpiece of the San Diego County Water Authority (SDCWA) Emergency Storage Project, the dam is designed to survive a major earthquake and ...

Case study - Fort Mandan visitor services center
The North Dakota Lewis & Clark Bicentennial Foundation has created a unique facility for one of the most vital sites on the Lewis & Clark Trail. The new visitor services center at Fort Mandan stands as a showcase for coal combustion products, while at the same time educating visitors about the journey of Lewis & Clark in North Dakota. Three major parts of the North Dakota: economy, ...

Case study - Fly ash concrete modified strength projects
In order to remain current with sustainable concrete design and construction practices, it is becoming more important to enable ready mix producers to supply innovative performance mixes that contain optimum percentages of fly ash. These mixes can be used to meet sustainable development practices, durability and exposure requirements, associated life-cycle costs, LEED building credits, economic ...

Why ‘custom-built’ is often cheaper than off the shelf
We know that we’ve said it before, but even though we list what we call our ‘standard range’, by far and away most of the incinerators and cremators we manufacture are specially designed and manufactured to match the individual needs of each customer. Since everyone’s requirements are different, virtually every unit we produce is ‘made to order’ and the point ...

Case study - High volume fly ash for the 2 Folsom project
High Volume Fly Ash (HVFA) concrete was successfully used as the cornerstone of this project’s sustainability program. HVFA concrete was aggressively pursued because of its environmental benefits. When fly ash is used in place of cement, energy and landfill space is conserved and greenhouse gas emissions are reduced. During this HVFA project, roughly 2,800 tons of CO2 emissions were ...

Pyrolysis
Introduction: Pyrolysis is formally defined as chemical decomposition induced in organic materials by heat in the absence of oxygen. In practice, it is not possible to achieve a completely oxygen-free atmosphere; actual pyrolytic systems are operated with less than stoichiometric quantities of oxygen. Because some oxygen will be present in any pyrolytic system, nominal oxidation will occur. If ...

Leaching of milled asphalt pavement amended with waste to energy ash
The environmental suitability of using Waste-to-Energy (WTE) ash as a partial substitute for aggregate in hot-mix asphalt concrete was investigated using a series of leaching lysimeters. Eight samples of processed asphalt concrete manufactured with 25% by weight WTE ash as aggregate were leached using stainless steel lysimeters. A ninth lysimeter contained asphalt without WTE ash. Simulated ...

Biomass Briquetting Plant For Processing Agro Waste
Fuel sources are required for a number of thermal applications like boilers, heaters, dryers and usually conventional fuel sources like coal, charcoal, diesel, petrol and liquid fuel are used. However these fossil fuel sources are expensive and polluting, containing sulphur, fly ash and other atmospheric pollutants which damage the environment. So increasingly businesses are using a biomass ...

Coal-fired power on the way out?
The past two years have witnessed the emergence of a powerful movement opposing the construction of new coal-fired power plants in the United States. Initially led by environmental groups, both national and local, it has since been joined by prominent national political leaders and many state governors. The principal reason for opposing coal plants is that they are changing the earth’s climate. ...

Cleaning Up Gasification Syngas
Documento sin título Introduction By definition, gasification is the art of changing a non-gaseous substance, such as a liquid or a solid, into a gas. By this definition, processes such as combustion, anaerobic digestion and pyrolysis would be classified as gasification. However, in today’s world, gasification is defined as any process, which produces a “synthesis gas” or a ...
