Secondary Heat Recovery from Exhausts and Oxidizers

Does it make sense to add secondary heat recovery systems to your thermal process to capture and repurpose the BTUs you have created before they escape out the top of the stack? An economic analysis can help you determine whether it is justified at your plant.

Secondary heat recovery systems capture excess energy in the exhaust stream of processes or oxidizers. On the surface, heat recovery makes good sense: Capture the waste energy and repurpose it rather than throwing it out an exhaust stack. The concept sounds relatively straightforward. As with most things, however, the proof lies in the details.

Improved NOx Limitation Standard to Reflect Combustion Efficiency

In many locations throughout North America, nitrogen oxide (NOx) emissions of gas-heated furnaces are limited by law or code. This is typically the case in urban areas or in places where special topographical characteristics intensify the negative local and regional effects of NOx emissions.

While the approach of limiting hazardous emissions is for the benefit of the environment and society, the method used to define the limitation can significantly alter its outcome (e.g., if it does not account for the full extent of influencing factors).
