Application Case | GF370 Remote Laser Methane Telemetry System for Gas Power Plant Safety

Optosky's gas monitoring instrument series includes online equipment, portable devices, and gas monitoring modules, applied in urban pipeline networks, petrochemicals, power and energy, and other critical fields, building a full-coverage intelligent sensing network. This case focuses on the successful application of the GF370 Remote Laser Methane Telemetry System at Datang Wanning Natural Gas Power Generation Co., Ltd., demonstrating the effectiveness of advanced laser telemetry technology in gas-fired power plant safety management.

01  Project Overview

Customer: Datang Wanning Natural Gas Power Generation Co., Ltd.

Application Direction: Gas Leak Monitoring

With the widespread adoption of natural gas power generation, safety risks in key operation areas such as turbine zones, pressure regulating stations, and startup boilers have continued to rise. In high-temperature, high-pressure, and high-gas-concentration environments, a leak could trigger uncontrollable accidents. Traditional manual inspection methods not only suffer from delayed response and blind spots but also rely heavily on operator experience, failing to meet the high standards of intrinsic safety management required by enterprises.

 

To address this, the customer demanded a long-distance, high-sensitivity, automated intelligent monitoring system for all-weather protection of critical locations. Leveraging its technological advantages and engineering experience in laser gas telemetry, Optosky customized the GF370 remote laser monitoring solution, establishing a comprehensive, non-contact, all-weather high-level gas safety prevention and control system.

02  Application Cases

On-site installation examples

The installation points in this project include critical areas such as the turbine core zone, pre-module, startup boiler, heating boiler, and natural gas pressure regulating station—all high-risk areas in natural gas transmission, pressurization, and combustion. To improve leak monitoring coverage and response speed, the customer needed an intelligent monitoring system capable of remote detection, automated patrol, high recognition accuracy, and strong adaptability, ensuring safety and stability across the entire operational chain.

03  Product Introduction

The GF370 uses Tunable Diode Laser Absorption Spectroscopy (TDLAS) technology, accurately identifying the unique absorption wavelength of methane molecules to achieve non-contact remote monitoring of gas leaks. It has a maximum detection distance of up to 150 meters (customizable to 200 meters), with μs-level response speed and high sensitivity, issuing early warning signals upon detecting trace leaks. The laser "fingerprint" feature ensures unique response to methane, eliminating interference from dust, water vapor, and other gases, guaranteeing accurate and reliable data.

 

Multiple GF370 units were deployed in key areas of the gas power plant. The integrated design combines a laser telemetry unit, high-definition camera, and full-speed pan-tilt unit, supporting 360° horizontal and ±90° vertical rotational scanning. The system supports automated patrol, power-off memory, remote control, as well as linkage with control systems, recording alarm information and automatically generating inspection reports. The equipment meets explosion-proof standards with IP68 protection rating, suitable for high-temperature, high-humidity, high-corrosion industrial environments.

 

Since commissioning, the equipment has operated stably with high sensitivity, building a solid line of intelligent inspection and risk prevention for the gas power plant, earning high recognition from the customer.
