Charcoal & Wood Pellet Moisture (& Ash) Matters
Welcome to Moisture Matters, the show where we take your everyday and not so everyday objects and test them to see which has more moisture. Today we’re doing something a bit different. We’ll be testing the moisture content AND the ash content of wood pellets and lump charcoal. So, which do you think will have more moisture and which do you think will have a higher ash content? The ...

Petrological characteristics of lower Gondwana coal from Singrauli coalfield, Madhya Pradesh, India
This paper entails the results of petrological studies carried out on coal samples drawn from two lower Gondwana coal bearing horizons (Raniganj formation and Barakar formation) of the Singrauli coalfield, Son basin. It emerges from this study that the coals of this basin are banded in nature and are dominated by ‘banded dull’ and ‘dull’ components. Further, vitrinite and inertinite are the ...

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 ...

Biomass Pellet Machine Fuel Can Replace Non-renewable Energy
The appearance of the biomass pellet machine makes biomass energy more fully utilized. The common straws, cottonseed hulls, peanut hulls, miscellaneous wood, various wood fragments, corn cobs, larch wood chips, rice husks, etc. in our life are very low-use and easily cause pollution, but they are all very good biomass pellet fuel raw materials. Today, there is a very good response to the use of ...

Modification of thermal and oxidative properties of biodiesel produced from vegetable oils
Trans esterification of three vegetable oils, sunflower oil, linseed oil and mixed oils as; sunflower-soyabean and olein were carried out using methanol, and potasium hydroxide as catalyst. The methyl esters of the corresponding oils were separated from the crude glycerol and characterized by physical-chemical methods to evaluate their thermal properties. This methods are determination of ...

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 ...

Characterization of biochar prepared from slow pyrolysis of Jordanian olive oil processing solid waste and adsorption efficiency of Hg2+ ions in aqueous solutions
Solid waste from Jordanian olive oil processing (OOSW) was used to prepare biochar samples by slow pyrolysis at terminal temperatures of 350, 450, 550 and 630 °C; henceforth known as BC-350, BC-450, BC-550 and BC-630, respectively. These samples were characterized by Fourier transform infrared spectroscopy, scanning electron microscopy and X-ray diffraction, ash content, moisture content and ...

Emissions and performance from a biomass boiler for different solid biomass fuels
During biomass combustion, a number of physical and chemical processes occur in time and space during the combustion. The processes include: drying and preheating of the fuel, pyrolytic release of volatile matter, glowing combustion char, etc. In general the combustion of biomass produces, next to energy, ash, carbon dioxide and monoxide, unburnt hydrocarbons, oxides of nitrogen, particulate ...
