Environmental Benefits and Energy Savings from Gas Radiant Heaters’ Flue-Gas Heat Recovery

This paper demonstrates the need and potential for using waste heat recovery (WHR) systems from infrared gas radiant heaters, which are typical sources in large halls, due to increasing energy-saving requirements buildings EU powerful wide-spread development of e-commerce market. The types heaters discussed classification WHR these devices is performed. article also presents first time our innovative solution, not yet available on market, exhaust gases ceramic heaters. energy analysis an industrial hall shows that this solution allows environmental benefits at different levels, depending heater efficiency, by reducing amount fuel emissions domestic hot water (DHW) preparation (36.8%, 15.4% 5.4%, respectively, case low-, standard- high-efficiency heaters). These reductions, considering both DHW heating, 16.1%, 7.6% 3.0%, respectively. key conclusion can spectacularly improve effect achieve highest level savings existing heated with lowest efficiency.
