1 Scope

GB 36660-2018 is the Chinese national standard on low-pressure carbon dioxide inerting protection equipment, in the field of environment and health protection, safety. 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 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 13.230, CCS C83. 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 terms and definitions, classification, model preparation, requirements, test methods, and inspection of low-pressure carbon dioxide gas inerting protection devices. Inspection rules, instructions for use in writing instructions. This standard is applicable to the preparation of coal powder in power plants, cement plants and other places and the low-pressure carbon dioxide gas used in natural gas transmission and distribution stations. Inerting protection device.

3 Terms and definitions

The following terms and definitions as defined in GB 19572-2013 apply to this document.

3.1 Inerting Explosion-proof technology that does not create an explosive atmosphere by filling the protective space with an inert gas.

3.2 Mixing a mixture of combustible gas (or dust) and air in a relatively confined space with carbon dioxide gas A device in which the oxygen content is below the explosive limit concentration to avoid explosion of the mixture.

3.3 Vaporizer vaporizer A device that converts liquid carbon dioxide directly or indirectly into gaseous carbon dioxide.

3.4 Water bath vaporizer water-bathvaporizer By heating the water in the vaporizer to exchange heat with liquid carbon dioxide, the liquid carbon dioxide is turned into a gaseous device.

3.5 Air bath vaporizer air-heatedvaporizer Air temperature vaporizer air-temperaturevaporizer The liquid carbon dioxide in the vaporizer conduit is heated by natural convection of the air to completely evaporate into a gaseous device.
