GB 38263-2019The norm of energy consumption per unit throughput of cement products (English PDF)

1 Scope

GB 38263-2019 is the Chinese national standard on the norm of energy consumption per unit throughput of cement products, in the field of energy and heat transfer engineering. It carries no /T suffix, which in the Chinese system means compliance is mandatory: a product or a practice within its scope has to meet it to be lawfully made, sold or carried out in China. It was issued on 14 October 2019 by the State Administration for Market Regulation; Standardization Administration of China, and has been in force since 1 May 2020. Classification: ICS 27.010, CCS F01. This page is published from the official record of the standard held by the Chinese standards administration: the identification, the dates, the classification and the issuing body are taken from there. The clause text, the tables and the numeric limits are in the document itself, which is delivered complete in English translation.

This standard specifies the terms and definitions, norm level of energy consumption, technical requirements, energy consumption statistics, calculation methods for the norm of energy consumption per unit throughput of cement products. This standard applies to the calculation and assessment of the energy consumption of cement product manufacturing enterprises, as well as the energy consumption control of newly built (renovated, expanded) projects.

3 Terms and definitions

The terms and definitions as defined in GB/T 12723 as well as the following terms and definitions apply to this document.

3.1 Comprehensive energy consumption of cement products During the reporting period, the total energy consumption of a certain type of cement product in the entire product production process from the entry of raw materials into the plant and the metering of energy into the process until the finished product exit-warehouse.

3.2 The comprehensive energy consumption per unit product throughput of cement products During the reporting period, the comprehensive energy consumption of a certain type of cement product expressed in terms of the unit (per cubic meter of concrete) qualified product throughput.

3.3 The coal consumption per unit throughput of cement products During the reporting period, the steam (or steam-producing fuel) consumption of a certain type of cement product expressed as the unit (per cubic meter) of qualified product throughput.

6.1.1.2 The calorific value of various energy sources shall be converted into a unified standard coal. The calorific value of various energy sources is based on the caloric value measured by the enterprise during the reporting period. If there are no actual measurement conditions, it shall use the reference coefficients for converting various standard energy sources as given in GB/T 2589.

6.1.1.3 The statistics and accounting of energy consumption shall include the above-mentioned various production links; it shall not be repeated or missed.
