At their board meeting on May 7, Southwest Georgia Technical College (SWGTC) recognized Cleaver-Brooks (Thomasville Plant) as the Thomas County representative for the 2013 Manufacturer of the Year Award.
Theoretical Efficiency Is Not the Proper Gauge of Actual Efficiency
Today’s published boiler efficiency ratings are calculated by manufacturers using a 15% excess air level, regardless of a burner’s actual ability to operate at that condition throughout the firing range
In recent years, burner technology advancements have led to the development of higher efficiency, lower emissions products. Burner engineers have made great strides in increasing burner turndown and lowering excess air levels even at the lower firing rates. At the same time, they have engineered ways to reduce NOX to single-digit levels.Burner Turndown.
The burner is the true driver of fuel use and costs in a boiler. Over time, linkage joints, cams, and other moving parts wear out, and a burner loses its ability to keep tight control of fuel-air ratio.
