智能煤质快速分析系统的研制

Development of an intelligent coal quality rapid analysis system.

介绍了一种基于热重分析原理的煤质分析系统。系统能自动连续分析燃煤中的水分、挥发分和灰分 ,根据分析结果计算出固定碳和高低位发热量。系统的特点是设计了多温区电加热炉和自动进样系统 ,加快了测试速度 ,缩短了测定周期。系统还具有飞灰可燃物测定功能。系统可用于燃煤电站等燃煤企业 ,保证锅炉燃烧的稳定和安全。

A coal quality analysis system based on thermogravimetry is described which can analyze water content, volatile component and ash of coal automatically and continuously. The fixed carbon and heat productivity can be calculated with the analytical results. The system features its multi temp zone electric heating furnace and automatic sample introduction device which were designed to increase testing speed and shorten testing time. It has also the function of determining combustables in fly ash. The system can be used in coal fired power station and other coal fired enterprises to guarantee the stability and safety of combustion in boilors.
