3 Terms and Definitions
The terms and definitions defined in GB/T 15604 and the following apply to this document.
3.1 Explosion suppression
A blast control technology that extinguishes flames in the initial stage of an explosion through physical and chemical actions, preventing unburned dust from participating in the explosion.
3.2 Automatic explosion suppression devices
Devices that automatically detect explosion information in the early stages of an explosion and use physical or chemical methods to extinguish or block flames.
3.3 Explosion detector
Instruments or devices that sense explosion information and convert and transmit available signals according to certain rules.
Note: Includes one or more explosion sensors.
3.4 Sensor and control device
Devices that detect and process combustion/explosion information and quickly trigger suppressors.
Note: Includes sensors and control instruments.
3.5 Suppressant
Substances that, upon contact with explosion flames, can absorb heat, insulate, reduce oxygen content, eliminate active groups, terminate combustion chains, etc., within a short time to prevent the explosion from continuing.
Note: Common suppressants include powder, liquid, and gas suppressants, which can be used independently or in combination.
3.6 Suppressor
Components that store and rapidly disperse suppressants.
3.7 Threshold pressure
The minimum response pressure of a sensor to a combustible dust explosion.
4 General Requirements
4.1 Enterprises shall identify and assess the risk of dust explosion propagation in production systems and select/design suppression devices based on process safety requirements.
4.2 Designers, manufacturers, and installers of suppression devices shall provide safety performance data and instructions and be responsible for the safety performance of the equipment.
4.3 Enterprises shall establish systems for installation, usage, maintenance, and operation of suppression devices, with designated personnel responsible for these tasks.
5 Technical Requirements for Explosion Suppression
5.1 General Requirements
5.1.1 Suppression devices shall disperse sufficient suppressant upon detecting an explosion signal to block flame propagation and reduce pressure in the early stage.
5.1.2 The maximum pressure in the system after triggering shall be less than the design pressure of pipelines, vessels, or equipment.
5.1.3 The installation position and spacing of explosion detectors and suppressors shall meet response time requirements without affecting normal operations.
5.2 Selection and Design of Suppression Devices
5.2.1 When selecting and designing suppression devices, the following process characteristics shall be obtained:
a) Existing explosion protection methods;
b) Potential ignition sources and their locations;
c) Design pressure of protected equipment;
d) Combustible dust concentration, gas flow, wind speed, and temperature in the suppression area.
5.2.2 The following explosion characteristics shall be understood:
a) Dust type and parameters (e.g., minimum ignition energy, temperature, maximum explosion pressure, explosion index);
b) Minimum suppressant concentration required for suppression.
5.2.3 The following installation information shall be specified:
a) Detector model;
b) Detector location;
c) Suppressor specifications and quantity;
d) Suppressor location.
