With an ever-increasing focus on energy efficiency and improving system performance, industrial processors are looking for ways to achieve these goals while reducing costs and material usage wherever possible. One proven way to increase energy efficiency and reduce fuel usage is to recover heat from industrial processes. Waste heat is unused heat given off by a process or equipment in the form of thermal energy — that is, heat not being captured to heat some other product or process. Waste heat can be thought of as free energy. Though, of course, there is a cost to create it, waste heat is thermal energy you would otherwise let escape up the stack rather than using in your process. Implementing ways to capture waste heat energy can improve efficiency while helping processors save money.
Even when fuel prices are low, companies in energy-intensive industries can see a benefit and enjoy a relatively short payback from utilizing some type of heat recovery system to improve the efficiency of their processes.
