Analysis of CO2 Emissions in the Whole Production Process of Coal-Fired

Three planning periods were set with different CO2 emission control desirability to simulate CO2 emissions of the different reduction requirements. The results can reflect the CO2 emissions across the whole production process of a coal-fired power Inhalable particulate emission, dust collection, and CO 2 emission control.

Life Cycle Modelling of the Impact of Coal Quality on Emissions

This paper presents a model combining the LCA (Life Cycle Assessment) of fossil fuel extraction with its quality parameters and related CO2, SO2 and dust emissions at the stage of the combustion process. The model which was developed aims to identify the environmental impact of the processes of electricity production from selected energy fossil fuel that causes emissions from power plants; however, in addition to emissions caused by coal combustion, mining activities also generate dust [6]. Dust emissions are measured as PM 2.5 and PM 10 in the mining industry and have been investigated by various researchers.

High-Energy Ejection of Molecules and Gas-Dust Outbursts in Coal

A distinctive feature of coal and gas emissions is the presence of finely ground—even down to the nanoscale—coal, the mass of which can be from 20% to 50% of the total outburst mass . Despite the abundance of papers discussing possible mechanisms for outbursts of coal and gas, the mechanism for generating coal dust remains unknown.Climate change and underlying global warming phenomena induced by CO 2 emissions from coal combustion and several other resources, causes the death of around 1.1–1.27 million people due to malaria each year (Gething et al., 2010).The growth of Plasmodium falciparum is highly dependent on temperature, particularly around or less Human health and environmental impacts of coal
