| Abstract Scope |
Heat recovery technologies have long been applied to industrial furnaces. Historically, their implementation has been concentrated on larger, high fuel-consumption furnaces, notably those employed in melting processes. Regenerative, as well as recuperative burner technologies have demonstrated substantial effectiveness across diverse furnace configurations, resulting in marked improvements in thermal efficiency. While natural gas prices may reduce the immediate economic imperative for fuel savings on lower-temperature, lower fuel consuming furnaces, the adoption of heat recovery systems offer additional significant benefits, including reductions in carbon emissions (CO2) and reduced gas volumes to downstream filtering equipment. Furthermore, with some consideration of hydrogen as an alternative fuel, given its likely much higher cost, maximizing furnace thermal efficiency remains an important objective for sustainable industrial practice. This presentation will examine the range of heat recovery options applicable to low-temperature furnace operations, and their resulting benefits. |
