Combustible Gas Detector FT - JW1: Methane Safety in Mines

Thermal power, as a core component of China's power system, continues to play a fundamental and safeguarding role in the current process of energy structure adjustment. This form of energy releases heat by burning fossil fuels such as coal, oil, and natural gas to drive generator sets. According to the latest energy statistics, the annual power generation of thermal power accounts for nearly 70% of the total national power generation. With a scale of 31.6 trillion kilowatt - hours, it maintains an absolute dominant position. Under the framework of the energy security strategy, coal, as the main raw material for thermal power production, has an annual consumption accounting for more than 80% of the total consumption of fossil energy, fully reflecting its strategic value in the operation of the national economy. It is worth noting that as of September 2024, the total national power installed capacity has exceeded 3.16 billion kilowatts, among which the installed capacity of thermal power reached 1.42 billion kilowatts, a year - on - year increase of 3.4%, and the installed capacity proportion has been steadily maintained at the level of 44.9%.

During the development and utilization of coal resources, mine safety has always been a key issue in the development of the industry. Gas explosion, as a major threat to the safe production of coal mines, accounts for more than 92% of the accident causes due to excessive methane concentration. When the concentration of methane gas in the roadway space reaches the explosive critical range of 5% - 16%, a chain explosion reaction will be triggered when encountering an open flame. Therefore, building an accurate and reliable real - time methane concentration monitoring system, achieving a detection accuracy of 0.01%vol through a distributed sensing network, and predicting risks 30 minutes in advance with the combination of intelligent early - warning algorithms has become the core technical path to improve the intrinsic safety level of coal mines. The popularization and application of such monitoring systems not only effectively reduce the incidence of major and extremely serious accidents but also promote the transformation and upgrading of the traditional mining industry to the intelligent direction through digital means.

The Combustible gas detector FT - JW1 is a gas detection device specifically designed for high - gas - risk places such as coal mines. It can monitor the methane concentration in real - time to ensure the safety of miners and workers. This detector uses a high - performance catalytic combustion methane sensor, combined with microcomputer digital technology and new electronic devices. It has high accuracy and high sensitivity, can accurately detect low - concentration methane, and timely discover potential safety hazards.

The FT - JW1 has an explosion - proof design. Its shell is made of materials with high strength and high sealing performance. It is small in size and light in weight, making it easy to carry. At the same time, it has water - proof and dust - proof functions and can adapt to various harsh underground environments. When the methane concentration exceeds the preset safety threshold, the detector will immediately issue an audible and visual alarm to remind personnel to take timely measures.

This detector supports a variety of measurement modes, including continuous monitoring and timed monitoring, to meet the needs of different scenarios. Its measurement range is CH₄: (0.00 - 4.00)%, the response time is not more than 20 seconds, and the basic error is between ±0.10% and ±0.30%.

The FT - JW1 is widely used in underground coal mines to monitor the methane concentration in real - time and prevent safety accidents such as gas explosions. It can also be used in the processes of natural gas exploration, transportation, storage, and use, as well as in fields such as chemical production, landfill, and sewage treatment.
