THE DEGREE OF A VACUUM CONTROL APPARATUS OF POWER PLANT CONDENSER

摘要

An apparatus for controlling the degree of vacuum of a power plant condenser is provided to improve efficiency of a power plant by maintaining optimum degree of vacuum of the power plant condenser. An apparatus for controlling the degree of vacuum of a power plant condenser(1) is mounted on a pipe(3) for interconnecting the condenser and an air ejector(2). The apparatus includes a main valve(4a) for adjusting the degree of vacuum of the power plant condenser, and an auxiliary valve(4b) arranged in parallel to the main valve. The main valve and the auxiliary valve are adjusted through a condenser vacuum adjusting unit(5). The degree of opening of the main valve and the auxiliary valve is adjusted in consideration of a wide variety of parameters.
