Technical path analysis of clean and efficient utilization of coal in Shajingzi mining area

Abstract

In Shajingzi mining area, the coal quality is very low, and many questions will be faced in the process of exploding the area. First, the author analyzed problems in resource development and utilization, and proposed the paths of clean and efficient utilization of coal, which are clean coal power generation technology (including SC, USC and near zero emission power generation technology), CHP energy saving and emission reduction technology, technical analysis of classification and quality utilization and coal transportation technology by pipeline. The author also analyzed the main characteristics in detail, which are high volatile content, high tar content, rich oil coal-high oil coal, and an ideal raw material for low temperature carbonization, tar hydro treating, semi coke gasification and CO combustion power generation. The author also summaries the advantages and disadvantages of coal transportation technology by pipeline, which is a new and efficient way of utilization. Finally, according to the development strategy of “clean, step-by-step, timely and comprehensive”, the author proposes the comprehensive industrial chain of coal, electricity and chemical industry will be the best path.
