Industrial steam supply system and method based on pressurized water reactor

The invention provides an industrial steam supply system and method based on a pressurized water reactor, the steam supply system comprises an air inlet flow channel and a first branch flow channel, the air inlet flow channel is used for receiving low-temperature and low-pressure steam of the pressurized water reactor; the first branch flow channel communicates with the air inlet flow channel, a heat pipe pile is arranged on the first branch flow channel, and the heat pipe pile is used for heating steam circulating in the first branch flow channel; and at least one second branch flow channel is arranged at the downstream of the heat pipe pile, and the second branch flow channel is used for pressurizing steam flowing out of the heat pipe pile or mixing the steam with the steam in the air inlet flow channel to obtain output steam with different qualities. According to the industrial steam supply system based on the pressurized water reactor, low-temperature and low-pressure steam provided by an existing pressur
