The present invention provides a solid fuel particle emission intensity measuring device for the high-temperature high-pressure gasification reactor. Such a solid fuel particle emission intensity measuring device for the high-temperature high-pressure gasification reactor according to the present invention can accurately and precisely measure the light intensity of the solid fuel particles to the combustion reaction in the high-temperature high-pressure conditions, used in this via Integrated Gasification Combined under high temperature and high pressure conditions, the ignition temperature of the coal char particles, solid fuel be precise and accurate detection becomes possible to derive the char combustion reaction rate.
Solid fuel particles, the emission intensity measuring device for the high-temperature high-pressure gasification reactor according to the present invention, the dark-shaped casing having a closed space with the outside light entering the block; Is fixed to one side surface of the darkroom type casing is exposed to the outside, becomes focused on the solid fuel particles placed in the predetermined position, passing the released solid fuel particles, the light emitted from the solid fuel particles emitted by the combustion reaction darkroom type measuring lens that enters the enclosed space of the casing and; Away from the lens measuring light detection sensor that is installed in the closed space of the casing dark, detecting the released solids is passed through a measuring lens introduced into the closed space the casing of the darkroom type fuel particles and the light; Connected to the light detecting sensor detects the solid fuel particle-emitting intensity of the light, and a controller which is to measure the solid fuel particles, the temperature of the combustion reaction of the detected solid fuel particle-emitting intensity of the light.
