The second phase 2 × 1000MW units re-heater emergency exit of Taishan Power Plant is electrical control, and has adjustment function. This emergency exit can realize quick opening under unusual service condition, and protect the re-heater. This system also has some shortcomings, such as the pressure switch is a single point protection, which is easy to maloperation; The air compressor running unstable; Can't replace the proportional electromagnetic with fault online. Conduct optimization and improvement against these prob?lems, and achieve the desired effect.
