NOTE 1 The general requirements on combustion furnaces are specified in JIS B 8415-1.

This Standard deals with significant hazards, hazardous situations and events relevant to combustion and fuel handling systems as listed in Annex A, when used as intended and under the conditions foreseen by the manufacturer.

This Standard covers the following:

— fuel pipework downstream of and including the manual isolating valve;

— combustion air supply (including oxygen and oxygen enriched combustion air) and flue gas system;

— burner(s), burner system and ignition device;

— functional requirements (protective system) for safety related control system (protective system).

This Standard applies to any oxidation with air or other gases containing oxygen of gaseous and liquid fuels, or any combustion of them to release thermal energy.

For thermal or catalytic post combustion and waste incineration, this Standard applies only to auxiliary burners designed to start-up and/or support the process.

The conditions concerning the pressure hazard of piping and components covered by this Standard shall be as specified in Annex E.

This Standard gives the necessary requirements regarding information for use.

This Standard does not cover hazards from heating generated by electricity.

This Standard does not deal with the hazards created by the release of flammable substances from the products processed in the combustion furnaces.

This Standard is not applicable to the following fuel handling systems:

— welding machines;

— up-stream of manual isolating valve of furnace equipment.

This Standard is not applicable to electrical cabling and power cabling upstream of the furnace equipment control panel/protective system.

NOTE 2 The International Standard corresponding to this Standard and the symbol of degree of correspondence are as follows.

ISO 13577-2:2014 Industrial furnaces and associated processing equipment— Safety—Part 2: Combustion and fuel handling systems (MOD)

In addition, symbols which denote the degree of correspondence in the contents between the relevant International Standard and JIS are IDT (identical), MOD (modified), and NEQ (not equivalent) according to ISO/IEC Guide 21-1.

Further, this Standard specifies the requirements to secure the safety of persons and devices against serious hazards such as predictable mistakes and malfunctions which can occur in the course of commissioning, operation and maintenance.

a) equipment of metallurgic/metallic processing plant

b) equipment of glass manufacturing plant

c) equipment in ceramics manufacturing plant

d) equipment in cement/quicklime/gypsum manufacturing plant

The details of industrial combustion furnaces to be applied are shown in Annex B.

This Standard is not applicable to the following:

— equipment in chemical plant and petroleum plant;

— waste incineration equipment;

— blast furnace and converter furnace in ironmaking plant;

— ambient gas generating device generating flammable gas, and ambient gas;

— equipment for burning in open space;

— equipment supplying flammable gas generated from heated materials (e.g. coke oven)

NOTE 1 An example of list of significant hazards is shown in Annex A.

NOTE 2 The International Standard corresponding to this Standard and the symbol of degree of correspondence are as follows.

ISO 13577-1:2016 Industrial furnaces and associated processing equipment— Safety—Part 1: General requirements (MOD)

In addition, symbols which denote the degree of correspondence in the contents between the relevant International Standard and JIS are IDT (identical), MOD (modified), and NEQ (not equivalent) according to ISO/IEC Guide 21-1.

This document deals with significant hazards, hazardous situations and events relevant to the converter plant. It covers the intended use and foreseeable misuse.

This document specifies the safety requirements to be met during design, pre-assembly, transport, site-assembly, commissioning, operation, maintenance (as described in Clause 5) and decommissioning/dis­assembly of the equipment.

Assembly does not include erection because national regulations, e.g. national civil engineering laws and regulations or occupational health and safety regulations contain such information.

This document applies to:

Steel converter and its associated equipment (see Annex B, Figure B.1 for the oxygen steelmaking process

—    from charging hot metal/liquid steel and scrap;

—    via oxygen refining and stirring;

—    temperature measurement and sampling equipment;

—    up to tapping including slag retaining device;

—    cooling systems;

—    maintenance devices (e.g. relining device, tap hole repair device, device for cleaning the converter mouth);

—    process related interfaces/interactions (e.g. according to design, controls) to

—    process media,

—    primary and secondary gas cleaning plant,

—    material feeding systems and ladle alloying systems,

—    transfer cars for steel ladle and slag pot, and

—    charging/tapping equipment, e.g. crane, scrap chute, ladles and slag pots.

This document does not cover safety requirements for:

—    usage of process media other than oxygen, nitrogen, argon and compressed air;

—    primary and secondary gas cleaning plants;

—    measuring devices with radioactive sources;

—    material feeding systems and ladle alloying systems;

—    transfer cars for steel ladle and slag pot;

—    charging/tapping and de-slagging equipment, e.g. crane, scrap chutes, ladles and slag pots;

—    auxiliary winches and hoists.

For variations of converter process where other gases and process media, e.g. hydrocarbons, fuels, steam, etc. are used, additional safety measures shall be considered which are not covered in this safety standard.

NOTE      In case of revamping, this document can be used as a guideline for the specific parts to be revamped.

This document is not applicable to steel converter and associated equipment manufactured before the date of its publication.
