Rotary hybrid radiation boiler

The invention discloses a rotary hybrid radiation boiler. The radiation boiler comprises a pulverized coal furnace and a heat recovery device, wherein the heat recovery device comprises a smoke inlet, a radiant heat exchange component and a convective heat exchange component, wherein the smoke inlet side of the smoke inlet is connected with the outlet of the pulverized coal furnace, the smoke outlet side of the smoke inlet is connected with the radiant heat exchange component, and the radiant heat exchange component is arranged on the upper end of the convective heat exchange component; the radiant heat exchange component comprises a radiation water wall and a radiation screen, the radiation water wall is of a cylindrical structure spliced by multiple vertical elongated pipes, and the radiation screen is positioned in the cylindrical structure of the radiation water wall; the radiation screen comprises multiple radiation sub-screens, the radiation sub-screens are dispersedly distributed by taking the central axis of the radiation water wall in the vertical direction as circle center. radiant heat exchange is performed on high-temperature smoke by virtue of the radiant water wall and the radiation screen, so that a radiant heat exchange section easily crosses over an easily-contaminated smoke temperature region and can not be condensed and adhered to a convective heated surface, and the problems of in-furnace coking, a heated surface and the like of a high-alkalinity coal power generator set are thoroughly solved.
