The importance of installing natural gas detector in boiler room. The main component of natural gas is methane, which is flammable and explosive. If the gas leakage encounters open fire, static electricity, lightning or improper actual operation, it will cause explosion and fire, and people will be deprived of oxygen, suffocated, or even died in the confined space. The installation of natural gas alarm can reasonably and effectively prevent the occurrence of explosion and fire, thus preventing the personal safety of property and relevant staff.
The function of the natural gas alarm is to monitor the gas leakage concentration. Once it exceeds the standard, it will immediately send out a sound to prompt the relevant staff to take safety measures. From its function, we can see the importance of gas alarm. If a gas alarm is installed, if we forget to turn off the gas source, once the concentration of natural gas exceeds the alarm value set by us, the alarm will remind us of gas leakage, and measures should be taken to prevent explosion accidents to a large extent.
Combustible gas alarm shall be set according to GB50041-2008 Code for Design of Boiler House. When there is volatile vapor of alkene gas or flammable and toxic gas in the air, the detector monitoring signal will be immediately transmitted to the alarm control unit according to the cable, and the controller will display the gas concentration. When the set alarm concentration value is exceeded, the alarm controller will send out sound and light alarm signals to ensure the production safety of the factory and prevent accidents.
The natural gas explosion is a combustion process that produces high temperature (up to 3000 ℃) and high pressure at a moment (one thousandth of a second). The explosion wave speed can reach 300 m/s, causing great destructive power. If the gas leakage encounters open fire, static electricity, lightning or improper operation, it will cause explosion accidents and fires, and people will be deprived of oxygen, suffocated or even killed in the confined space, causing incalculable losses to the production safety of the unit and the life and property of the country and people.

Problems needing attention when handling gas leakage:

Organize treatment in strict accordance with relevant regulations and procedures for gas leakage in boiler room.
Timely contact with relevant departments of gas companies and heating companies, and disconnect the supply of natural gas; Natural gas must be replaced according to regulations; Those who need to go through the hot work procedures must go through the procedures according to the regulations, and those who need professional teams for maintenance must appoint qualified professional teams for construction.
For all kinds of possible leakage accidents, organize the preparation of relevant treatment plans and emergency plans, and drill the emergency plans.
Reserve special materials for handling leakage accidents, emergency fire-fighting materials, testing tools, etc.
To deal with the leakage, the full-time safety officer of the workshop shall be assigned to take charge of the site and carry out relevant technical disclosure to relevant personnel.
After processing, it is necessary to ensure that all materials are used up and the site is clear after completion of the work, and carefully fill in the information of technical data.
