Co-firing ramie residue with coal was carried out in a thermogravimetric analyzer and a cyclone furnace to evaluate the effects of coal fraction (0 to 30 wt. %) on combustion performance. Thermogravimetric analysis (TGA) results showed that devolatilisation was the predominant process when the coal percentage in the blend was below 30 wt. %. For pure biomass firing in the cyclone furnace, an op...

Background: Certain marker studies have practical importance in the biology of prostate cancer. The purpose of this study was to determine whether the quantification of certain neuroendocrine and proliferative markers obtained during transurethral resection or prostatectomy, would help in the prognostic evaluation of prostatic adenocarcinomas. Methods: The present study was performed on samples...

A series of experiments were performed to determine rock mechanical parameters related to was studied. Experimental results show that the coal seam in the study areas has a relatively low elastic modulus, high Poisson’s ratio, high fragility and is easily broken and compressed. The coal seam is considered as a transversely isotropic medium, since the physical properties in the direction of bedd...

The amount of electrical energy produced over the lifetime of coal, LWR fission, DTfusion, and wind power plants is compared to the total amount of energy required to procure the fuel, build, operate, and decommission the power plants. The energy payback ratio varies from a low of 11 for coal plants to a high of 27 for DT-fusion plants. The magnitude of the energy investment and the source of t...

X-ray diffraction (XRD) analysis is a fundamental method to evaluate the carbon stacking structure in coal and carbon materials. However, the vagueness of XRD pattern of coal, which has the low crystallinity, often makes it difficult to evaluate the stacking structure quantitatively. In a previous study [1,2], we reported the standard analysis of carbon stacking structure in coal by XRD techniq...

In this work, a system is proposed for safe Coal Mine Monitoring, which plays an important role in coal mine safe production. Wi th continuous enlarging of exploiting areas and extension of depth in coal mine, many laneways become monitoring blind areas, wh ere are lots of hidden dangers. It is very difficult to lay cables which are not reliable and not effective. For to overcome this , a new s...
