煤的发热量测定中的注意事项

Attentions in measuring the coal calorific value

针对煤的发热量测定中氧弹的气密性检查、热容量的标定、搅拌器故障或搅拌速度不均匀、测定前量热仪的校准等方面应注意的事项进行探讨,并指出测定难燃煤、低热值煤、高挥发分煤的发热量时可采用包纸、添加苯甲酸或压饼等相应措施。

Notices in measuring the coal calorific value which needs attention in aspects such as gas tightness inspection of oxygen bomb, calibration of heat capacity, agitator failure or uneven mixing speed and calibration of calorimeter before the determination were discussed in this paper.Corresponding measures such as paper package, adding benzoic acid or doing cake of press were adopted when measuring the calorific value of unburnable coal, low calorific value coal and high volatile coal.
