4.4.1 When the measured dry calorific value of the coal is not equal to the standard calorific value, the sulfur content should be converted to obtain the converted decomposition basis content and then graded according to Table 2 or Table 3 based on the newly calculated decomposition basis content. The calculated decomposition basis content is the standard, and the actual measured decomposition basis content will be the calculated decomposition basis content =

) Adjustment of the content of sulfur content in coal
CB/T 15224.2—2004
When the ten-dryness basic high temperature heating value of the coal is not equal to the basic temperature E, and the age classification range of the basic temperature is different from the values specified in Table 2 and Table 3 in the text, it is necessary to adjust according to the measured ten-dryness basic high temperature heating value. When the lower basic temperature heating value of the coal is based on the high standard temperature heating value, the classification range values in Table 2 and Table 3 in the text should be adjusted accordingly: When the ten-dryness basic temperature heating value of the coal is lower than the full standard temperature heating value, the classification range values in Table 2 and Table 3 in the text should be adjusted lower. For this reason, this appendix lists the basic high calorific value of coal at various low temperatures, and reports the range value for the overall classification: the actual recorded drying temperature is not equal to the accurate calorific value when the whole sulfur classification standard is adjusted according to the following formula: the whole classification standard value = the actual measured calorific value of the commercial drying temperature is equal to the benchmark calorific value of the whole research classification standard value || tt|| the smoke and smoke media are not equal to the benchmark calorific value. The ear is classified according to Table A.1 of this appendix. The sample period of the high-rise calorific value of the tooth mold is not subject to the standard calorific value. The classification is carried out according to Table A.2 of this appendix: Table A:1 Smokeless and smoke-free classification quota adjustment value actual dry Huanlai
