GB/T 26126-2018Commercial coal quality—Coal for industrial pulverized coal-fired boiler (English PDF)

Foreword

This standard was drafted in accordance with the rules given in GB/T 1.1-2009.

This standard replaces GB/T 26126-2010 "Technical conditions for coal for small and medium-sized pulverized coal industrial boilers", this standard and GB/T 26126- Compared with.2010, the main technical content changes are as follows.

--- The standard name was changed to "commercial coal quality coal powder industrial boiler coal";

--- The scope was revised to "this standard specifies the quality grade and technical requirements, test methods, inspection rules, and coal quality standards for coal-fired industrial boilers. Identification, transportation and storage";

--- Increased the division of coal and pulverized coal products for pulverized coal industrial boilers, graded according to calorific value and total sulfur index, to "heat" Formal representation of the grade full sulfur grade;

--- Added Appendix A product catalog.

1 Scope
