ABSTRACT:
A system for concentration of waste cooling tower blowdown in a steam turbine power plant. The cooling tower blowdown feed is withdrawn from a main power plant condenser and is recirculated through an auxiliary cooling tower and an auxiliary condenser. The auxiliary condenser utilizes waste heat steam drawn from the main condenser as an energy source. Evaporation continuously takes place in the auxiliary cooling tower concentrating the cooling tower blowdown so that it may be withdrawn and sent to a concentrating pond or other slurry handling station for final disposal.
