Exploitation of Heat from Thermal Active Coal Tips

Article Preview

Abstract:

Burning tips of colliery spoil represent long-term ecological hazard. History of these processes in the Ostrava region is more than 20 years long. The attention in the past was in case of burning tips given to control, even to remediate underground fires. Thermal potential of burning tips has remained unnoticed. Just in last five years in Czech republic and abroad it has started to experiment with heat exploitation originating during tips burning. Trial tests with heat exploitation in the Hedvika tip in Ostrava were successful and they produced even economic contribution. Verification of marginal conditions has been already a topic of ongoing research. Hazards during heat exploitation from thermal active coal tips are as follows: migration of thermal spots, difficult temperature regulation of the surroundings from which heat is taken, aggressiveness, and from it resulted demands to materials used in this technology.
