Thermal Camera for Flame Detection in Flare Stack
Flare stacks, commonly known as a flare tower is a vertical structure commonly found in oil and gas industries, petrochemical industries, and chemical processing plants. These are mainly used to safely burn off or combust hazardous gases that cannot be processed or stored. 
They act as an essential safety measure to prevent the release of harmful gases in the environment. In the flare stack, the excess gases are transferred to the flare stack and burnt in a very controlled manner by converting them into carbon dioxide and water vapour.
As the burning of the hazardous gases is a very critical process in nature, government and environmental authorities regulate strict laws to monitor this process continuously and have regular fault detection and monitoring mechanisms to ensure smooth running of the system. The authorities also force industries to implement up to date technologies that can reduce or capture the emissions accurately.
Pyrosens Solution:
Infrared Flare Stack Monitoring System from Pyrosens is a high-resolution Thermal Imaging based solution for main as well as for pilot flame monitoring. In this solution, Pyrosens Thermal Imaging camera is coupled with a suitable lens and is put inside a weather-proof stainless-steel enclosure or ATEX enclosure to prevent the camera from dust, rain, sunlight and other hazardous environment conditions. 
This can also be equipped with automated alarm systems. If the temperature exceeds predefined thresholds or if any anomalies are detected, the system can trigger alarms, notifying operators or emergency response teams.
System Composition:
A Thermal Imaging flare stack system comprises the following components.
- High Resolution Thermal Imaging Camera(640 x 480/384 x 288 pixels)
