boiler manufacturers and water treatment companies recommend
boiler water TDS be maintained at certain levels. The
purpose of continuous blowdown is to continuously take
boiler water from 4" -6" under the surface
where the TDS is at its highest concentration so that
it can be replaced with fresh water. While continuous
blowdown is the best way in controlling these solids
in the boiler the heat lost to drain over time can be
tremendous. Penn Crossover or Shell & Tube Continuous
Blowdown Heat Recovery Systems can recover up to 95%
of this heat normally lost. Two stages provide the recovery.
The first stage uses a Penn Flash Separator where the
high pressure condensate flashes to a low pressure steam
use such as a feedwater heater or deaerator. The second
area a separate heat exchanger that transfers the remaining
heat to boiler Make-up water.
