Aluminum Recycling Plant Emergency Service & Burner Tuning
At an aluminum smelting plant outside St. Louis, production was running at full demand when one of their furnace burner systems suddenly stopped lighting. With a large automotive manufacturer relying on a steady supply of molten aluminum, every hour of reduced throughput created mounting pressure to get the system back online.
The facility operates six large furnaces, each pulling roughly 10,000 pounds of aluminum per hour at full capacity. When one burner system failed to light, output on that furnace dropped to 5,000–6,000 pounds per hour — threatening their contractual obligation to a major automotive manufacturer next door. With the customer physically on site asking for a repair timeline, the pressure was immediate and very real.
MOST’s internal team tried to troubleshoot, but like many modern plants, they didn’t have an in-house combustion specialist. As BDC has heard from countless customers, the days of having a burner expert on staff are long gone — most maintenance teams are generalists now, stretched thin and expected to keep dozens of systems afloat at once.
What Was Actually Wrong with the Furnace?
At first glance, the issue looked like the burner simply wasn’t lighting. But the problem ran deeper. The furnace wasn’t getting enough gas flow through its ratio regulator — a critical component that matches gas pressure to combustion air pressure at a 1:1 ratio. When the regulator is sized wrong or becomes degraded by heat and age, it can’t keep up.
The air valve opened the way it should, but the gas pressure never followed. The regulator was not opening fully, so the furnace simply couldn’t generate the heat required to reach operating temperature.
The plant had contacted the OEM for the part and got a quote: $15,000 per regulator with a 14-week lead time. Waiting three and a half months wasn’t an option. They needed to restore full, reliable burner operation immediately.
Emergency Response: How BDC Restored Full Production in Under 24 Hours
BDC sent a technician right away. In emergency service scenarios like this, response time is often the difference between maintaining production and shutting down an entire product line.
Once onsite, our tech diagnosed the undersized ratio regulator as the root issue. Without enough gas flow, the industrial burners were starving, and the furnace temperature couldn’t recover.
Because BDC represents all major brands, and isn’t limited to a single equipment line, the technician had options. Instead of waiting on a specific like-for-like part with a multi-month lead time, he was able to replace the failed regulator using valves and actuators that BDC already had in stock.
This flexibility is a major differentiator for BDC. In emergency situations, you don’t have the luxury of waiting for OEM timelines. You need a compatible solution that gets you operational now.
Results: No Lost Contract, No Shutdown, and a Safer, More Stable Furnace
This situation highlights a challenge many industrial facilities know all too well: OEM parts are expensive, backordered, or simply not available within a production-friendly timeline. With a failed ratio regulator and a 14-week lead time from the original manufacturer, the plant faced the risk of prolonged reduced throughput, and the contractual consequences that come with it.
Because BDC represents all major brands, the technician wasn’t limited to a single product line or constrained by OEM delays. Once installed and tuned, the furnace immediately returned to its full 10,000-pound-per-hour melt rate. The facility avoided interruption to its supply flow, stayed on pace with Toyota’s production needs, and preserved the stability of its smelting operation. The plant team could shift their focus back to running the process, not fighting equipment limitations.
