1 Scope

GB 29438-2012 is the Chinese national standard on the norm of energy consumption per unit product of polyoxymethylene, 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 31 December 2012 by the General Administration of Quality Supervision, Inspection and Quarantine of the People's Republic of China; Standardization Administration of China, and has been in force since 1 October 2013. 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 POM unit product energy consumption (referred to as "energy") technical requirements limit, the scope of statistics and calculation methods, as well as Energy management measures. This standard applies to the calculation methanol and ethylene glycol as the main raw material of POM energy producers, assessment, and new projects of Energy control.

5 range and statistical calculation method

5.1 statistical range

5.1.1 POM overall energy consumption statistics ranging from industrial alcohol, ethylene glycol and other raw materials and steam, water and other materials and industrial power Start metered into the polyoxymethylene means, the amount of primary energy to the finished product storage bag until the actually consumed, the amount of secondary energy, and work energy Mass (such as water, oxygen, nitrogen, compressed air, etc.). Recycled

5.1.2 polyoxymethylene means waste heat of chemical reaction heat and the like, the amount of energy should not be included. If the heat and energy and Chemical reaction heat, etc. for use in other devices, which should be deducted from the actual utilization of the energy consumption of the present system.

5.1.3 various heat value of the fuel to be equivalent to a uniform unit of measurement kg coal (kgce) or tce (tce). All kinds of heat energy Calorific value of enterprise value measured during the reporting period shall prevail. Found no conditions, can refer to Appendix A and Appendix B of various energy given off Reference coefficients of coal, various types of coal off energy working medium energy reference coefficients.

5.1.4 Energy consumption statistics, accounting should include the various production processes and systems.
