Size effect on uniaxial compressive strength of single ...

2019-3-1  Thus, the yield strength, crushing strength, and ultimate strength of a single coal particle with a fixed diameter under uniaxial compression can be approximated as follows: (23) σ dy = 4 P fy π d 2, σ dc = 4 P fc π d 2, σ du = 4 P fu π d 2 where P fy, P fc, and P fu are the forces at the yield point, crushing point, and ultimate point, respectively. It can be generally considered that the tensile strength of the

Effects of pyrite on the spontaneous combustion of coal

2017-8-28  Pyrite has a significant effect on the spontaneous combustion of coal. The presence of pyrite can change thepropensity of coal towards spontaneous combustion. The influences of various pyrite contents on the parameters ofspontaneous combustion, such as index gases, temperature and released heat etc., were investigated in this study. Coalsamples with different pyrite contents (0 %, 3 %, 5 %, 7 % and 9 %) were made by mixing coal and pyrite. The oxidationexperiments under temperature-programmed condition were carried out to test the release rate of gaseous oxidationproducts at different temperatures. Differential scanning calorimeter (DSC) was employed to measure the intensity of heatrelease during coal oxidation for various pyrite contents. The results indicate that pyrite can nonlinearly accelerate theprocess of spontaneous combustion. The coal sample with a pyrite content of 5 % has the largest CO release rate andoxygen adsorption as well. However, the coal sample with a pyrite

Numerical investigation of the effects of size

2019-1-15  Coal particle combustion behaviors are not only affected by the size segregation in the coal plume but also by variations of the coal plume itself. Images of flame recently captured in the front of the tuyere peephole from several industrial blast furnaces proved that the variation of coal plume had a strong influence on the coal combustion in the raceway as well as the activity of the hearth [ 41 ].
