Fired Heater Thermal Surveys

Fired Heater Thermal Surveys
Fired heater tube metal temperatures (TMTs) are a critical process variable. Measurement errors are common, resulting in producers running at sub-optimal loads where false-high readings are taken, or reliability issues and tube failures with false-low values.

    A unique service for the thermal optimisation of furnaces, the In-Furnace Glass Survey produces real-time and recorded images for analysis, supplementing traditional refractory inspections.

    The survey helps to improve glass application productivity with optimised pull rates, and increases thermal and combustion efficiency, lowering fuel costs. It protects the refractory from damage, extending campaign life, and optimises the flame pattern to reduce energy consumption. It also helps ensure energy compliance.

    Combining near-infrared borescope thermal imaging with portable multi-gas analysis, the In-Furnace Glass Survey is carried out by an experienced engineer at a specified number of furnace locations. 

    Tailored to specific application requirements, the In-Furnace Glass Survey is suitable for refractory processes in the glass industry, including the manufacture of float, borosilicate, and container glass, as well as melt furnaces and fibre glass production.

    Optimised for measuring high temperatures between 1000 to 1800°C (1832 to 3272°F), the NIR-B Glass creates detailed and live high-resolution images from within the furnace. Dedicated image processing software ensures accurate data analysis. The Lancom 4 portable multi-gas analyser measures up to eight flue gases for the optimisation of combustion and emissions processes.

    Using a negative image, the In-Furnace Thermal Glass Survey reveals where there is too much or insufficient cooling. Excessive cooling increases emissions and leads to refractory wear, as the batch piles drag along the lining. A software-based isotherm function identifies refractory areas below 1388oC (2530oF), where sodium hydroxide can condense, corroding silica refractory.
    Small rat holes and other damage can be identified and located before they become apparent on the exterior, making them easier and less costly to repair than larger holes. A further survey will be able to confirm the success of the repair, reducing the need for any re-work.
