As a follow-up to our previous posts regarding St Louis HVAC service near Overland and some of the heat recycling methods out there, we are going into more detail about bottoming cycles. “Bottoming cycles are mostly used in industrial facilities in the chemical, paper, and primary metals sectors, as these industries often have high-temperature waste streams that are favorable for waste heat recovery. As much as 20-50 percent of the energy consumed in some industrial processes is ultimately lost through waste heat contained in streams of hot exhaust gas and liquids and through heat conduction, convection, and radiation from hot equipment surfaces and heated product streams.”
The goal, so to speak, is a simple one that applies to only some processes as others may not be safe enough when it comes to the waste they produce. The overall energy efficiency of some industrial processes can be improved by capturing and reusing the waste heat, however, in situations where it makes sense from a safety and function point of view. In our recent research on behalf of your St Louis HVAC installation near Overland MO, we discovered many facts surrounding the process to share here and in posts to follow.
“In some cases, such as industrial furnaces, efficiency improvements resulting from waste heat recovery can improve energy efficiency 10-50 percent. A study by the U.S. Department of Energy’s (DOE) Energy Efficiency and Renewable Energy office (EERE) identified research, development, and demonstration efforts to expand waste heat recovery practices in the U.S. industrial sector.” In the aforementioned study, the waste streams analyzed showed that roughly 60 percent of unrecovered waste heat is low quality (i.e., temperatures below 450°F). We will explore more regarding what this means as we further our research into heat recycling and HVAC in St Louis.
