micro size coal
解釋
微粒度煤-
This paper consists of the following parts : firstly, the physical properties ( particle size distribution, specific area, porosity ratio and pore volume ) and pyrolysis characteristics have been studied in experiments with four kinds of coals. according to experimental results, the advantages of combustion characteristics of micro - pulverized caols are analysed on the theory. secondly, the reconstructing plan is designed in details for a conventional system of the hot air transferring pulverized coal to reduce nox emission
本文主要包括以下內容:首先,通過基礎的實驗分別對四種具有代表性煤種一、三次風所含煤粉的物理特性(粒徑分佈、孔隙率、孔容積和比表面積)和熱解特性進行研究,從理論上分析煤粉細化后,較細顆粒(即三次風含粉)在燃燒特性上的優越性,為三次風含粉用於再燃燃燒打下基礎。
