Hot Spot Detection for Critical Vessels

Provides a Continuous, Accurate and Reliable Solution for Process Monitoring and Fault Detection


Throughout the Power Generation and Chemical/Refining industries, many vessels operate at high temperature and pressure. This makes them susceptible to risk of failure as the refractory lining degrades or the process changes. The consequences of undetected refractory breakdown can be catastrophic – fire, explosions, loss of life – causing major monetary losses due to spoiled product and production downtime.

Viper's System Solution

The illustration portrays a typical design for Viper’s Hot Spot Detection System (in this example, a Gasifier) using FLIR A-series cameras. Viper’s design places 2 – 32 cameras around the vessel ensuring the most complete heat map possible. The camera’s digital data stream is connected via Ethernet to the ViperVision control system. The ViperVision software controls all camera functions, collects temperature data, displays thermal images and analyzes data.


Key Benefits

  • Maximum protection greatly reduces risk to plant personnel and equipment
  • Early Detection of refractory breakdown
  • Reliable and rugged system designed for harsh environments
  • Increased revenue with consistent production
  • Easy integration into existing plant control system

System Solution Components

FLIR cameras are integrated with the ViperVision software which directly communicates with most industrial platform controllers. The software will analyze and compare the data against predefined parameters and will trigger an alarm if warranted. These parameters can be adjusted based on the specific application needs.

Every thermal imaging camera is mounted in an industrial camera enclosure that uses the appropriate purge and pressurization to protect the camera equipment. Viper Imaging provides solutions for Class I and Class II environments that are Division I or II.

Some Examples of Viper’s System Solution

In this process, fuel is converted to hydrogen using heat. Viper’s system is beneficial for monitoring the collection header by seeking refractory degradation. See the corresponding image for how this degradation is evident by the “hot spot.” Prevent unsafe conditions and product loss!

Viper’s approach to Hot Spot Detection for critical vessels eliminates or minimizes the installation of point contact temperature sensors such as thermistors, thermocouples, RTDs, or solid-state devices. Avoid the guessing game of whether contact sensors are placed in the correct location relative to process flows and reaction locations. Viper’s design eliminates this concern by monitoring the entire vessel and its surface, providing instantaneous non-contact temperature measurements. FLIR cameras’ digital data stream is connected to the ViperVision control system. The ViperVision software controls all camera functions, collects temperature data, displays thermal images and analyzes data. Engineers now have the data they need to make critical decisions about vessel repair and renewal.

Viper’s systems utilize a wavelength optimized infrared optical system to see through the smoke, ash and haze produced within high temperature kilns. The system is typically installed on the hot end of the kiln with fiber optics or the plant network which transmits video and data from the kiln to the control room. The operator will have real-time video of the process interior displayed on high resolution monitors.
