Save energy with a high-turndown boiler

A food processing plant replaced bent-tube atmospheric boilers (maximum efficiency 75% to 80% at 100% output) with a high-efficiency, high turndown boiler (efficiency 85% or higher at loads from 35% to 100%).

In a year-over-year comparison, from November, 2004 to November 2005 the plant cooked 46% more product with 12% higher fuel consumption, resulting in a 30% increase in per-therm productivity and 23% decrease in gas usage per pound of product.
