由中国统配煤矿总公司主持召开的动力煤发热量计价技术研讨会,于1990年9月11日至9月18日在常州召开,会议就动力煤发热量计价方案、动力煤发热量与灰分、水分的相关关系及计算机在谋质研究中的应用进行了研讨。中国煤炭科学院煤化学所的陈文敏教授在会上讲解了计算动力煤发热量的原理和公式,论述了发热量与灰、水及其它因素的关系。姜宁工程师介绍了计算机的发展及计算机在煤质分析和发热量计价中的应用。通过研讨,大家一致认为,动力煤按发热量计价是煤炭计价方案的重大改革,它比灰分计价更合理。
The seminar on thermal coal pricing technology hosted by China National Coal Mine Corporation was held in Changzhou from September 11 to September 18, 1990. The meeting discussed the thermal calorific value pricing scheme, thermal coal heat and ash content , The relationship between water and computer in the study of the quality of the application were discussed. Professor Chen Wenmin from Institute of Coal Chemistry, Chinese Academy of Coal Science, explained the principle and formula for calculating the calorific value of thermal coal at the meeting and discussed the relationship between calorific value and ash, water and other factors. Jiang Ning engineers introduced the development of computers and computers in the analysis of coal quality and calorific value of the application. Through the discussion, we all agreed that thermal coal pricing by calorific value is a major reform of the coal pricing scheme, which is more reasonable than the ash pricing.
