The number of combustible gas alarms installed is not static, but needs to be flexibly adjusted according to actual conditions. Otherwise, the number of combustible gas alarm installation does not match, then it will not be able to give full play to its role, therefore, we only ensure that the number of combustible gas alarm and potential risks match, in order to really play its role, better protect the safety of life and property. Do you know how to determine the number of combustible gas alarms installed? The following is an introduction to yiyuntian electronic editor:

To determine the number of combustible gas alarms to be installed, the following aspects need to be considered:

1. the size and ventilation of the inspection area

In general: combustible gas alarms should be installed at least every 25 to 100 square meters.This means that the distance between each combustible gas probe should not exceed 5 to 10 meters.

Indoor space: According to experience, the effective detection area of each combustible gas alarm is about 25 to 30 squares.

2. gas leak source and leak possibility

: in areas where there are sources of gas leakage, such as tank farms, distillery tank farms, etc., combustible gas alarms need to be installed more intensively. For example, in tank farms, combustible gas alarms are generally installed at intervals of 3 meters.

poorly ventilated area: when installing combustible gas alarm in closed place or semi-open workshop with local poor ventilation, the range covered by combustible gas should not be more than 5m from any release source.

3. Detection Gas Types and Characteristics

<: when the detection is heavier than the air of combustible gas, combustible gas alarm installation height should be from the floor (or floor) 0.3m ~ 0.6m; when the detection is lighter than the air of combustible gas, combustible gas alarm installation height should be released within 2.0m above the source.

Diffusivity: Due to the diffusivity of combustible gas, combustible gas alarms should be installed above or around possible leakage points in order to detect gas leakage in time.

4. special area requirements

Key areas: in key areas where there may be a large number of gas leaks, such as near gas equipment, gas pipelines or gas equipment, the number of combustible gas alarms should be increased to ensure that leaks are detected in time.

Multi-point detection: For large areas or complex environments, it may be necessary to set up multiple combustible gas alarms for multi-point detection to ensure that the entire area is within the monitoring range.

In summary, we can see that the number of combustible gas alarms installed should be based on multiple factors such as the size of the detection area, ventilation conditions, gas leakage sources and leakage possibilities, detection gas types and characteristics, and special area requirements. At the same time, during installation, relevant national standards and regulations should also be followed to ensure the effectiveness and reliability of the combustible gas alarm.
