G.CONDENSATE REMOVAL AND TREATMENT
The condensate generated during normal boiler operation must be
removed in accordance with local codes and regulations. The
condensate can be piped to a local treatment system or run into the
optional condensate treatment assembly. Regardless of the method
used, a trap (Figure 2-27) must be installed on the condensate
outlet to prevent discharge of the flue gases from the boiler.
H.CONDENSATE TANK INSTALLATION
A boiler condensate collection tank or gravity drain is required. The
condensation piping must incorporate a water trap approved by the
local authorities. The water trap must be filled with water prior to
commissioning and checked or refilled at each required
maintenance interval. The water trap is required to prevent discharge
of flue gases into the boiler room.
Notice
The condensate occurring during operation in both the boiler and the flue
gas pipeline has to be neutralized and piped to a safe drain. The conditions
for the discharge of condensates into public drain systems are determined
by the local authorities and municipalities.
The responsible authority will inform you of any requirements for
raising the pH value from 4.3 to the frequently prescribed higher
value. The CFC neutralization system contains the granulate
NEUTRALAT which comprises natural components and brings
about an increase in pH of the condensate flowing through it. The
neutralization system comprises the plastic neutralization tank with
condensate inlet, a base screen plate, filter mat, granulate chamber
and condensate outlet (see Figure 2-28). The system is installed in
the CFC lower collection area.
