Scope: The main content of this standard is the method for measuring the calorific value of low calorific value raw fuel materials. It also includes the determination of the combustion heat of slow quantitative filter paper, sample preparation, sample processing, reagent configuration, equipment requirements, repeatability limits, and reproduction. Conversion of sexual limits and benchmarks, etc. The key to the technology is to treat a representative sample with dilute acid to achieve the purpose of deashing, which facilitates the measurement of the calorific value of the sample. For low calorific value raw fuel materials with large ash content, the acid treatment deashing process of the sample needs to be verified. During the measurement process, factors such as the influence of the heat generated by the filter paper and ignition wire on the test results should be examined to minimize the detection error. We should also consider the practicality and applicability of the method and make it scientific and rigorous.
