Foreword

This document is drafted in accordance with the rules given in GB/T 1.1-2020 "Directives for standardization - Part 1: Rules for the structure and drafting of standardizing documents".

This document replaces GB 21344-2015 "Norm of energy consumption per unit product of synthetic ammonia", GB 29138-2012 "The norm of energy consumption per unit product of monoammonium phosphate", GB 29139-2012 "The norm of energy consumption per unit product of diammonium phosphate", GB 29439-2012 "The norm of energy consumption per unit product of potassium sulfate", GB 31829-2015 "Norm of electricity consumption per unit product of ammonium bicarbonate" and GB 32035-2015 "Norm of energy consumption per unit product of urea". Compared with GB 21344-2015, GB 29138-2012, GB 29139-2012, GB 29439-2012, GB 31829-2015 and GB 32035-2015, apart from structural adjustments and editorial changes, the main technical changes are as follows:

a) the scope of application of the standard has been changed (see Clause 1; Clause 1 of GB 21344-2015, GB 29138-2012, GB 29139-2012, GB 29439-2012, GB 31829-2015 and GB 32035-2015);

b) the definition of granulation of potassium sulfate has been added (see 3.11);

c) the energy consumption limit indicators for synthetic ammonia, urea, ammonium bicarbonate, monoammonium phosphate, diammonium phosphate and potassium sulfate have been changed (see Clause 4; Clause 4 of GB 21344-2015, GB 29138-2012, GB 29139-2012, GB 29439-2012, GB 31829-2015 and GB 32035-2015);

d) requirements for the energy consumption limit of synthetic ammonia produced from lignite have been added (see Clause 4);

e) an additional energy consumption allowance for winter production with the Mannheim process in cold regions and an additional energy consumption allowance for granulated potassium sulfate products have been added (see 4.6);

f) the boundaries of the production systems for monoammonium phosphate and diammonium phosphate have been changed (see Clause 6; 3.3 and 3.4 of GB 29138-2012 and GB 29139-2012);

g) the utilization rate of ammonia has been changed (see 6.2.2.3; A.3.1 of GB 21344-2015);

h) the energy-saving management and measures have been deleted (Clause 6 of GB 21344-2015, GB 29138-2012, GB 29139-2012, GB 29439-2012, GB 31829-2015 and GB 32035-2015).
