Steam reheating equipment of coal-fired power generating unit

The utility model discloses steam reheating equipment for a coal-fired power generating unit, which relates to the technical field of coal-fired power generating units and comprises a boiler body, a reheating mechanism is arranged outside the boiler body and comprises a fire grate, a first steam pipeline and a second steam pipeline, and the fire grate is fixedly connected with the boiler body. The boiler body, the fire grate, the first steam pipeline, the second steam pipeline, the air pump, the first steam temperature detector, the high-temperature reheater, the third steam pipeline and the second steam temperature detector are arranged in a matched mode, low-temperature steam formed by power generation acting can be reutilized, and the low-temperature steam becomes condensate water after being cooled; the condensate water flows into the high-temperature reheater and forms high-temperature steam again after being heated through the high-temperature reheater, the high-temperature steam formed again is conveye
