Problems solved by technology

Due to the large water consumption on the secondary side of the steam generator, the hot water required for heating cannot be continuously filled at one time, and can only be realized by heating and injecting water in sections by a large heating water tank tank car. The equipment occupies a large space and has low heating efficiency. lower

Abstract

The invention belongs to an electric heating water tank, particularly relates to a high power density electric heating water tank for secondary pre-service hydraulic pressure test of a steam generator, which comprises a cylinder, an electric heater, a water inlet pipe and a water outlet pipe; the heating end of the electric heater is located inside the cylinder, the water inlet pipe is arranged at one end of the bottom of the cylinder, and the water outlet pipe is arranged at the other end of the bottom of the cylinder. The water tank has smaller volume, high heating power and high thermal efficiency and can realize quick temperature rise of a secondary shell of the steam generator.

Description

technical field [0001] The invention belongs to an electric heating water tank, and in particular relates to a high power density electric heating water used for heating the secondary side casing of the steam generator before the hydraulic test of the secondary side of the steam generator of the pressurized water reactor nuclear power plant (station). . Background technique [0002] The pre-service hydraulic test of the secondary side of the steam generator is an important node and milestone in the installation process of the nuclear island equipment of the PWR nuclear power plant. According to the test procedure of this test, the secondary side shell of the steam generator must be raised to a certain temperature before the pressure boost test, and the temperature during the pressure boost and pressure relief test of the steam generator secondary side must not be lower than that of the shell. The temperature at which the bulk material becomes embrittled. [0003] In the pa...
