弱粘煤低温干馏中试装置理论计算及性能评价

he article use the weakly caking coal of Xinjiang Yili area as raw material, through analysing the basis data of materia,select alumina ball as a heat carrier and dry distillation process at low temperature method .Based on the 100 kg wet coal , calculat the material balance and heat balance based on annual coal capacity of 20000 t low temperature distillation pilot plant equipment. At the same time, further calculates the carbonization furnace section strength and charge flow and residence time and other major performance indicators, analysis and evaluation of the retort furnace thermal efficiency and dry distillation energy consumption, provide the reliable theory and actual basis for the future realization of product design, process improvement, energy consumption of the minimum and the maximum economic benefit .
