GB 30526-2019The norm of energy consumptions for unit product of sintering wall materials and cellular glass (English PDF)

1 Scope

GB 30526-2019 is the Chinese national standard on the norm of energy consumptions for unit product of sintering wall materials and cellular glass, 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 norm grade, technical requirements, statistical range and calculation method of energy consumption for unit product (hereinafter referred to as energy consumption) of sintering wall materials and cellular glass. This Standard applies to the calculation and assessment of energy consumption of fired perforated brick and block, fired hollow brick and block, fired heat preservation brick and block, sintered solid products and thermal insulation cellular glass production enterprises, as well as the energy consumption control of the new (rebuilt, expanded) enterprises or production lines.

3 Terms and definitions

Terms and definitions determined by GB/T 2589, GB/T 4132, GB/T 12723 and the following ones are applicable to this document.

3.1 The comprehensive energy consumption for unit qualified product of sintering wall materials The sum of various energy sources that are used for the production of unit qualified product of sintering wall materials in the statistical period, which is converted according to the prescribed calculation methods.

3.2 The comprehensive energy consumption of cellular glass The total amount of various energies that are actually consumed in the production of cellular glass during the report period.

3.3 The comprehensive energy consumption per unit product of cellular glass The energy consumption, that is converted into tons, of the total energy consumption in the production process of cellular glass, which is based on the output of qualified products in the report period.

3.4 Fused glass A solid material that is obtained by mixing materials such as quartz sand, wax stone, soda ash and so on in a certain proportion, and clarifying into a glass liquid by melting in a kiln, and cooling through a cooling pool.

Note: fused glass is a raw material for the production of cellular glass.

4 Energy consumption norm grade
