1 Scope

GB 21344-2023 is the Chinese national standard on norm of energy consumption per unit production of fertilizer industry, 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 27 November 2023 by the State Administration for Market Regulation; Standardization Administration of China, and has been in force since 1 December 2024. 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 document stipulates the energy consumption per unit product of synthetic ammonia, urea, ammonium bicarbonate, monoammonium phosphate, diammonium phosphate and potassium sulfate (hereinafter referred to as Energy consumption) limit level, technical requirements, energy consumption statistical scope and calculation method: This document is applicable to the calculation and assessment of energy consumption of production enterprises of synthetic ammonia, urea, ammonium bicarbonate, monoammonium phosphate, diammonium phosphate, and potassium sulfate: and energy consumption control in new construction, renovation and expansion projects: This document does not apply to the following manufacturing companies:
