Effect of steam injection into incinerator on thermal destruction of waste refrigerant (HFC-134a).-.
The reuse of hydrofluorocarbons (HFCs) with a global warming potential (GWP) of >150 is prohibited in developed countries. Decomposition and subsequent neutralization of the produced hydrogen fluorides is currently widely used for the treatment of high-GWP waste HFCs. However, there is the need to reduce the high auxiliary energy consumption of the utilized incinerator. For this purpose, we developed two versions of a burner for injecting fuel, oxidizer, refrigerant, and steam into the incinerator. The simultaneous supply of the waste HFCs and steam into the incinerator was expected to enhance the destruction of the former, thereby reducing the energy consumption. The following were determined from the results of experiments that were performed to evaluate the effectiveness of the developed type-1 burner.
