Customer case:

Improving recovery boiler safety

Jul 18, 2023

A North American pulp mill was looking to improve the operations and safety of their recovery boiler. They invested in a Valmet Furnace Imaging System, IR (Portable Mid-IR mobile inspection camera) with off-axis lens to safely manage the firing rate of their boiler. The Portable Mid-IR mobile inspection camera kit contains everything needed to inspect a boiler from any accessible port. The mobility kit is housed in a single wheeled case and includes an air filter and connection hose, rechargeable batteries and charger, and a heat shield to protect the user.
