<p>The present invention relates to a combustible gas combustion controller of a pressurized light water reactor of a nuclear plant and, more specifically, to a combustible gas combustion controller which is installed at a rear stage of a pipe generating the combustible gas or a rear stage of a filtration ventilation system in a pressurized light water reactor of nuclear plant to convert the combustible gas such as hydrogen, carbon monoxide, etc. to water vapor, carbon dioxide, etc. and stably discharge the converted gas, and installed on the nuclear power plant which autonomously operates without an external power source. The combustible gas combustion controller according to the present invention comprises: a combustible gas inlet hole (100) wherein the combustible gas is introduced at a lower end thereof; a quenching mesh (200) which is positioned above the combustible gas inlet hole (100); an air inlet hole (120) which is installed above the quenching mesh (200), wherein air is introduced to the air inlet hole; and a recombiner (300) of a honeycomb structure which is installed above the air inlet hole (120). The combustible gas inlet hole (100) is installed on a nuclear power plant chimney (700) such that the combustible gas introduced into the combustible gas inlet hole (100) reacts with the air introduced into the air inlet hole (120) in the recombiner (300) and is converted into the water vapor and carbon dioxide and then discharged. The combustible gas combustion controller according to the present invention is installed on the chimney, performs a stable combustion control with no hydrogen explosion probability through the recombination reaction of the combustible gas, prevents toxic carbon monoxide from being discharged, and prevents a backflow of the flame through the quenching mesh (200).</p> |
