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. The simultaneous supply of
steam and waste HFCs into the incinerator increased the internal temperature of the incinerator when using either version of
the type-2 burner. With the simultaneous supply of steam and the HFCs, the internal temperature of the incinerator increases
with increasing steam supply, regardless of the version of the burner used. When using the type-2 burner, by which steam is
supplied to the incinerator in the same direction as the flame, the NOx concentration decreases from 71 ppm to 62 ppm with
increasing steam feed rate. In the case of using the type-1 burner, there is no decrease in the NOx concentration. The HFCs
decomposition rate is 100% for a HFCs feed rate of up to 2.8 kg/h with no steam supply, while the 100% decomposition is
maintained up toHFCs feed rates of 3.0 and 3.4 kg/hwhen using the types 1 and 2 burners with steamsupply.The decomposition
rate of the HFCs for the two types of burners are the same for steam
feed rates above 0.5 kg/h.
