HANDLING OF COAL DUST AT COAL HANDLING FACILITY IN COAL POWER PLANT USING SOFT SYSTEM METHODOLOGY (SSM) APPROACH

Jurnal Ilmiah SINERGI, 2019
Currently, many coal-fired powers plants are built to supply electrical energy needs in Indonesia due to relatively inexpensive raw materials and abundant in Indonesia.

Nutrition Status of Trees on Spoil Heaps After Coal Mining Can Be Inferred From Seasonal Dynamics of Foliar Nutrient Concentrations

Land Degradation &Development, EarlyView.
ABSTRACT A stable vegetation cover on given habitat conditions can be one of the possible requirements for post‐mining sites, as it can prevent erosion and dustiness of these anthropogenic surfaces and bring several practical future benefits, such as biomass production and microclimate improvement.

Compound preparation and performance evaluation of biodegradable dust suppressant agent for ultrafine coal dust

Meikuang Anquan
The problems such as poor wettability of ultrafine coal dust (mass fraction of coal dust with a particle size less than 5 μm is not less than 50%) have seriously restricted the effect of mine dust control.

Coal Mining as a Driver of Land Use and Land Cover Change and Degradation: A Case in Moatize City, Mozambique

Land Degradation &Development, EarlyView.
ABSTRACT Coal remains a major global energy source despite ongoing environmental controversies, particularly, regarding climate change and landscape transformation. This study investigates the spatiotemporal dynamics of land use and land cover (LULC) in the Moatize Coal Basin (MCB), Mozambique, between 1990 and 2024, with a specific focus on land ...

The Coal-Dust Question [PDF]

Nature, 1885
ON several occasions during the last five years, Sir Frederick Abel has referred to the history of the coal-dust question, and to my connection therewith; and as his views on this subject do not altogether correspond with mine, I desire, with your permission, to state in this place how much, and in what particulars, I differ from him.

The IceShark, an effective method for sampling plankton under sea ice

Limnology and Oceanography: Methods, EarlyView.
Abstract Seasonal sea ice plays a crucial role in shaping coastal ecosystem dynamics throughout the circumpolar region. Of particular interest to oceanographers is the ice‐ocean interface which functions as a multidimensional habitat, supporting both sympagic algae and pelagic phytoplankton in the under‐ice surface waters.

Study on the characteristics and mechanism of inert powder inhibition of gas/coal dust compound explosion

Meitan kexue jishu
Gas/coal dust composite explosion is a complex process that combines homogeneous and heterogeneous combustion. The combustion main control mechanism changes dynamically and the explosion mechanism is more complex, resulting in higher explosion ...

Recent Developments in Sustainable Composites for Printed Circuit Boards (PCBs): A Review

Macromolecular Materials and Engineering, EarlyView.
This review presents the potential of using natural plant fibers and biodegradable polymers as sustainable printed circuit boards (PCBs). This review provides future directions in innovation and sustainable PCBs development. Bio‐composites PCBs are both environmentally friendly and sustainable due to the natural fibres they contain.

Research of the coal dust size range influence on low-temperature vortex combustion based on numerical simulation [PDF]

, 2015
Low-temperature vortex combustion numerical simulation was performed using FIRE-3D software. Low-temperature vortex combustion aerodynamic and heat-and- mass transfer versus coal dust size range characteristic were analysed.
