ENVIRONMENTALLY FRIENDLY TECHNOLOGY SUPER ABSORPTION
The flue and stack must be heat-insulated and provided with a damper
and a condensate drain.
The flue should never be connected to an incinerator stack.
Locate the top end of the smoke stack at a sufficiently large distance
away from the cooling tower.
Figure 29. Typical flue and stack installation
Flue & stack connection
If the same stack is used for discharging exhaust from two systems, the
back flow of exhaust should be prevented from going into the one which
is out of operation.
Provide a draft regulator if fluctuations in static pressure are expected
inside the flue.
As illustrated, the steel stack should be lined on the interior surface as a
protection from corrosion due to exhaust gas.
Typical steel stack
Municipal codes in many areas may regulate large capacity chillers con-
suming oil or gas as fuel.
Such regulations should be strictly abided by.
Compliance with local regulation
NOTES :
Please design the draft pressure at flue flange of the chiller/heaters with
negative pressure 0 thru -29.4Pa (0 thru -3mmH2O).
