Detonation Burning of Coal
Results of an experimental study of continuous spin detonation of a coal-air mixture with addition of a certain amount of hydrogen in a plane-radial vortex chamber 500 mm in diameter are presented. The tested substance is fine-grained cannel coal from Kuzbass having a particle size of 1 - 7 μm and containing 24.7 % of volatiles, 14.2 % of ashes, and 5.1 % of moisture. Stable regimes of continuous spin detonation with transverse detonation waves with velocities of 1.86 - 1.1 km/s with respect to the cylindrical wall of the chamber are obtained for the first time. The mass fraction of hydrogen is 1.5 %- 0.88 % of the air flow rate and 50% - 3.4 % of the coal consumption rate. A system for supplying the coal powder into the combustion chamber is worked out.
