Foreword

All clauses of this standard are mandatory except 4.11, 5.1.1, 5.1.2, 5.1.11, 5.4.8 and 5.1.14.

This standard replaces GB 16543-1996, Safety regulations for explosion prevention and protection on bituminous coal injection system into blast furnace.

Compared with GB 16543-1996, the main differences are as follows:

- the non-standard format of the original standard has been corrected (the title of Clause 2, "Referenced standards", has been changed to "Normative references"; the title of Clause 3, "Definitions", has been changed to "Terms and definitions");

- the terms and definitions "multi-pipe injection process", "mixed coal", "inert gas", "raw coal storage and transport system" and "venting tube" have been added;

- the person responsible for safety in maintenance has been added (see 4.1);

- the hazard factors to be controlled in design and production have been added [see 4.3 a), l), m), n)];

- more detailed and specific requirements have been set for the design departments of bituminous coal injection systems into blast furnaces (see 4.6);

- the safety training of operators of bituminous coal injection systems into blast furnaces has been detailed (see 4.9);

- safety requirements for "mixed coal injection" and "bituminous granular coal injection" have been added (see 4.10, 4.11);

- safety acceptance requirements before trial operation of blast furnace bituminous coal injection projects have been added (see 4.12);

- requirements for drawing up accident emergency rescue plans have been added (see 4.13);

- the requirements for flow velocity in coal conveying and coal injection pipelines have been changed (see 5.3.4);

- the requirement for water spraying devices in the raw coal storage system has been added (see 5.6.7);

- the safety measures to be taken in case of fire in pulverized coal bins and coal mills have been added (see 7.5.7, 7.5.8).
