6 FAQs about [Coal mine air-deficient oxidation power generation]
How can coal mine ventilation air methane reduce the environmental impact?
In order to minimise the volume and environmental impact of coal mining wastes and coal processing by-products (as well as coal mine ventilation air methane, or VAM) while producing clean electric power, a new process concept, as illustrated in Fig. 7, has been proposed .
How much methane is emitted by coal mining?
The methane emitted by coal mining is called “ventilation mode”, and the concentration is as low as 1% or less 3, which is mainly divided into three parts: ( a) mine ventilation air (0.1–1.5% CH 4) 4, ( b) methane drained from the seam before mining (60–95% CH 4) 5, and ( c) methane drained from worked areas of the mine (30–95% CH 4) 6, 7.
Does oxygen concentration affect thermal oxidation of coal?
Under lean-oxygen conditions, the oxygen concentration has less effect on the mechanism function most likely to describe the thermal oxidation process of coal. Meanwhile, there was a kinetic compensation effect during the CSC under the lean-oxygen atmosphere.■
Do coal ranks affect oxidation and combustion under lean-oxygen conditions?
Based on TG analysis, the CSC process was divided into three stages and described with critical values. The results showed that the coal ranks have a negative effect on coal oxidation and combustion under lean-oxygen conditions. The difference in the critical temperature of differentcoalswassmallastheoxygen concentration varied.
How does coal mining affect the quality of coal?
In order to produce coal and upgrade coal quality, coal mining inevitably generates large volumes of low heating value wastes, including coal gangue, waste coal, and coal washery rejects, which are dumped near mine sites.
Does oxygen concentration affect kinetic behavior of high-rank coals at low-temperature oxidation?
The reaction mechanisms of high-rank coals at a low-temperature oxidation stage were more influenced by oxygen concentration than low-rank coals. Evaluations of kinetic behavior showed that activation energy decreased in a linear manner as the oxygen concentration decreased.
