Customer Case | Optosky Pan-Tilt Laser Methane Telemetry System Enhances Safety Prevention and Control at Natural Gas Power Plant

01  Application Background

User Unit: Datang Wanning Natural Gas Power Co., Ltd.

Application Focus: Gas leak monitoring.

With the widespread adoption of natural gas power generation, safety risks in key operational areas such as turbine zones, pressure regulating stations, and start-up boilers continue to rise. Particularly in high-temperature, high-pressure, and high gas concentration environments, any leakage can potentially lead to uncontrollable accidents. Traditional manual inspection methods not only suffer from delayed response and blind spots but also heavily rely on personnel experience, making it difficult to meet the enterprise's high standards for intrinsic safety management.

In this context, the customer required a higher level of gas safety monitoring, necessitating an intelligent monitoring system capable of long-distance, high-sensitivity, and automated operation to provide round-the-clock protection for critical sites. Leveraging its technical expertise and engineering experience in laser gas telemetry, Aopu Tiancheng customized a GF370 remote laser monitoring solution for the customer, establishing a comprehensive, contactless, and 24/7 high-level gas safety prevention and control system.

02  Case Study

Installation points for this project included key locations such as the core turbine area, front-end modules, start-up boilers, heating boilers, and the natural gas pressure regulating station—all high-risk areas within the natural gas transportation, pressurization, and combustion processes. To enhance leak monitoring coverage and response speed, the customer required an intelligent monitoring system capable of remote monitoring, automatic cruising, accurate identification, and strong adaptability to ensure the safety and stability of the entire operational chain.

03   Product Introduction

GF370 Pan-Tilt Laser Methane Telemetry System utilizes Tunable Diode Laser Absorption Spectroscopy (TDLAS) technology. By precisely identifying the unique absorption wavelength of methane molecules, it achieves non-contact remote monitoring of leaking gas. The device offers a maximum monitoring distance of 150 meters (customizable up to 200 meters), with microsecond-level response speed and high sensitivity. It can detect trace leaks and quickly issue early warnings. The laser's "fingerprint identification" characteristic ensures exclusive response to methane, eliminating interference from dust, moisture, and other gases, guaranteeing accurate and reliable monitoring data.

This project involved the deployment of multiple GF370 systems in critical areas of the natural gas power plant. Featuring an integrated design, the system combines a laser telemetry unit, a high-definition camera, and a fully adjustable variable-speed pan-tilt mechanism, supporting 360° horizontal and ±90° vertical rotational scanning. The system not only supports automatic cruising, power-off memory, and remote control but can also integrate with control systems, record alarm information, and automatically generate inspection reports. The equipment meets explosion-proof standards and possesses an IP68 protection rating, making it suitable for complex industrial environments with high temperature, high humidity, and high corrosion.

Since deployment, the equipment has operated stably and responded sensitively, establishing a robust line of defense for intelligent inspection and risk prevention and control at the natural gas power plant, earning high recognition from the customer.
