Walsn Energy Furnace CO Monitoring System: Protecting Boiler Water Walls at the Source

In the daily operation of thermal power plant boilers, water wall corrosion, furnace wall slagging, and sudden tube ruptures remain major challenges for on-site operators and maintenance engineers. Often, incomplete combustion generates local high CO concentrations near the water walls, creating a reducing atmosphere. Over time, this leads to gradual tube wall corrosion, increased slagging, wall thinning, and eventual sudden tube ruptures — resulting in unplanned outages, high maintenance costs, and significant losses in power generation.

Walsn Energy’s furnace CO online monitoring system is engineered specifically for the harsh conditions inside boiler furnaces — high temperatures, heavy dust, and strong corrosion. The system arranges fixed monitoring points at designated locations to continuously collect CO concentration data in the near-wall regions of the water walls, enabling precise detection of abnormal local reducing atmospheres.

The system incorporates wear-resistant, anti-clogging sampling probes designed for reliable long-term operation in boilers. Monitoring data integrates directly into the plant’s Distributed Control System (DCS), giving operators immediate visibility into the furnace combustion atmosphere.

With real-time CO insights, operators can fine-tune air distribution, optimize local combustion conditions, and reduce high-CO accumulation near the walls. This delivers multiple benefits:

- Reduces high-temperature corrosion and slagging on water walls

- Lowers the risk of water wall tube ruptures and unplanned shutdowns

- Improves overall combustion efficiency and cuts energy losses from incomplete combustion

The solution effectively balances unit safety and economic performance. By shifting from traditional reactive, post-failure repairs to data-driven proactive adjustments, the system aligns with the industry trend toward refined, predictive operations and maintenance in thermal power generation.

Grounded in real power plant needs, Walsn Energy’s furnace CO monitoring solution provides robust technical support for the long-term safe and efficient operation of boiler water walls, helping plants achieve greater stability and productivity.
