Case Study 1: Replacement and Repair of Thermal Fluid Heating System at a Biomass Mill
Sigma Thermal engineered a temporary blind while still giving them access to the damaged equipment so it could be replaced. This allowed the customer to run half of their process and maintain
production with the other half of their system.
This project consisted of replacing 2 natural draft burners with 2 forced draft burners, along with all the required supporting parts required to make the change. Once the project was installed, the service group went on site to fine tune the new burners. This change greatly reduced the start-up time for the heaters – as the purge time for a natural draft burner is near 15 minutes – where the forced draft is closer to 2 minutes.
Sigma Thermal made required modifications to the heater lid, fuel train, electrical system, and controls, all of which were included in this project.
