Inlet piping 2 of the flammable gas concentration control system recombination device 1 shown in FIG. The outlet pipe 3 is connected to the inlet pipe 2, and the processing gas containing hydrogen and oxygen gas in the reactor containment vessel is connected to the inlet pipe 2.
After passing through the gas inlet flow rate control valve 4 and raising the pressure with the blower 5 and raising the temperature with the coil-shaped heating tube 7 heated by the heater 6, the hydrogen and oxygen reaction in the recombiner 8 causes After being reduced to steam and cooled in a cooler 9, steam and water are separated in a steam separator 10, and the water is returned to the reactor containment vessel through an outlet pipe 3. If the hydrogen concentration contained in the inlet gas exceeds the specified value, a part of the treated gas is returned to the inlet and diluted. A recirculation operation is performed to dilute the hydrogen concentration in the inlet gas. (Japanese Unexamined Patent Publication No. 49-126593 is a prior art document.) [Problem to be Solved by the Invention] By the way, the above-mentioned combustible gas concentration control system recombination device has a coil-shaped coil on the outside of the recombiner 8.

This is one of the factors. Furthermore, since a high-voltage power source is required, the cost of ancillary equipment is also high.
