GB/T 1028-2018Industrial surplus energy resources evaluation methods (English PDF)

Foreword

This standard was drafted in accordance with the rules given in GB/T 1.1-2009. This standard replaces GB/T 1028-2000 "Industrial waste heat terminology, classification, grade and calculation method of waste heat resources". Compared with GB/T 1028-2000, the main technical changes of this standard are as follows:

--- Expanding waste heat into residual energy and perfecting terms related to residual energy (see Chapter 2, Chapter 2 of the.2000 edition);

--- Removed the terminology of common industrial waste heat recovery equipment (see Chapter 2 of the.2000 edition);

--- Improved the classification of industrial residual energy (see Chapter 3, Chapter 3 of the.2000 edition);

--- Improved the evaluation method of industrial residual energy resources (see Chapter 4, Chapter 4 of the.2000 edition);

--- Added a comprehensive evaluation table of industrial residual energy (see 4.7). This standard is proposed and managed by the National Energy Foundation and Management Standardization Technical Committee (SAC/TC20). This standard was drafted.

1 Scope

GB/T 1028-2018 is the Chinese national standard on industrial surplus energy resources evaluation methods, in the field of energy and heat transfer engineering. The /T suffix marks it as a recommended standard: it is not compulsory by itself, but it becomes binding as soon as a contract, a tender or a customer specification calls it up - which in practice is how most foreign buyers meet it. It was issued on 17 September 2018 by the State Administration for Market Regulation; Standardization Administration of China, and has been in force since 1 April 2019. 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 defines terms related to industrial residual energy and specifies the classification and evaluation methods for industrial residual energy. This standard applies to the evaluation of industrial residual energy resources.

2 Terms and definitions

The following terms and definitions apply to this document.

2.1 Yuen surplusenergy The industrial production process system consumes the input energy and outputs the available energy.

2.2 Remnant carrier surplusenergycarrier Contains residual energy.

2.3 Remaining energy quantityofsurplusenergy The amount of energy.

2.4 Theory can use the remaining energy theoreticalyavailablequantityofsurplusenergy Based on the standard environmental parameters (temperature 25 ° C, pressure
