GB/T 28398-2023Norms of energy consumption statistics for coal enterprises (English PDF)

Foreword

This document complies with the provisions of GB/T 1.1-2020 "Standardization Work Guidelines Part 1: Structure and Drafting Rules of Standardization Documents" Drafting.

This document replaces GB/T 28398-2012 "Statistical Specifications for Energy Consumption of Coal Enterprises". Compared with GB/T 28398-2012, except for the In addition to structural adjustments and editorial changes, the main technical changes are as follows:

a) The terms "gross industrial output value", "industrial added value", "comprehensive energy consumption per 10,000 yuan of output value", "comprehensive energy consumption per 10,000 yuan of industrial added value" and "waste "Other utilization of waste", "Energy consumption of coal washing (preparation)", "Loss in energy processing and conversion", "Energy processing and conversion efficiency" (see 2012 Versions 3.1~3.4, 3.11, 3.12, 3.16, 3.17);

b) Added the terms "raw coal production" and "coal consumption" (see 3.1 and 3.2);

c) Changed the terms "energy consumption of coal production", "energy processing and conversion", "energy processing and conversion input" and "energy processing and conversion output". The definition of "output" (see 3.4, 3.9~3.11, 3.6, 3.13~3.15 of the 2012 edition);

d) Changed the terms "energy consumption of coal enterprises" to "comprehensive energy consumption of coal enterprises", and "waste utilization energy saving" to "waste energy consumption". "Waste recycling energy", and its definition has been changed (see 3.3 and 3.8, 3.5 and 3.10 of the 2012 edition);

e) Changed the "Energy Statistics Type" (see 4.8, 4.7 of the 2012 version);

f) Added the principle that solid waste is not included in energy consumption (see 4.7);

g) Added the principles for statistics of physical and standard consumption of a single energy variety (see 4.10);

h) The calculation method of comprehensive energy consumption of coal enterprises has been changed (see 7.1, 2012 version of 7.1).
