弹式热量计是一种用于测量煤的燃烧热性能的仪器。最近人们开始意识到测量的不确定性，主要有两个原因。实验室认证一直在稳步增长，这需要对测量的不确定度进行估计，特别是在校准领域。其次，随着制造公司通过正确校准检验、测量和测试设备来关注测量的可靠性，质量体系认证的成熟度提高了。煤炭的质量是由灰分、风干水分、挥发分、总热值、硫含量等各种参数决定的。煤炭的品位决定于煤炭的品质，煤炭的品质决定着发电的性能。弹式量热仪的测量不确定度受到各种参数的影响。本文描述了方法、不确定性计算以及各个因素对其的影响。
A bomb calorimeter is an apparatus used for measuring the performance of coal in term of heat of combustion. Recent awareness has been created regarding uncertainty of measurement, due to mainly two reasons. Laboratory accreditation, which has steadily been on the rise, which requires a estimation of uncertainty of measurement particularly in the field of calibration. Second, increased maturity level of the quality system certification as the manufacturing companies looking at the reliability of measurement through correct calibration of inspection, measuring and test equipment. The quality of coal is decided by the various parameters such as ash content, air dried moisture, volatile matter, gross calorific value and sulphur content etc. The grade of coal is decided by the quality of coal which decides the performance of generation of electricity. The uncertainty of measurement in bomb calorimeter gets affected by various parameters. This paper describes the methodology, uncertainty calculations and effects of individual factors on it.
