Getting the most out of your combustion system means focusing on higher productivity, lower costs, reduced environmental impact and increased product quality. Readers have seen how thermal capture can save costs and increase productivity, but what environmental impact does this technology have? Is there any effect on product quality? The good news is that the development of energy-efficient industrial burners can now meet air-quality standards while giving operators better control of how and where the heat is delivered.
Let’s take an in-depth look at the technical basis details for enabling the use of preheated air burners that meet environmental and quality standards. We’ll look first at methods for controlling NOx emissions, with details from simple Excel burner models in downloadable workbook NOxControl.xlsx. Then we’ll look at ways of using burner controls to enhance heat transfer to a furnace’s load and maintain temperature uniformity in a furnace.
