Certainly during the first and subsequent haating intervals, excessive air condensation on the boiler surfaces may occur; in the ash
section, a dark fluid may appear. This is due to the low water temperature in the boiler (below the condensing point of 65 °C) and
the low flue gas temperature. The condensing will cease after partial burning of the combustion products on the walls and after
melting above 65 °C. In any case, this is not a leakage of the boiler. Every boiler is thoroughly tested with overpressure and the
possibility of leackage is virtually eliminated.
Air condensation occures:
•
at low draft of the chimney. If this is permanently low, it is removable only by a structural modification. If temporarily
low, it is due to weather conditions
•
with wet fuel
•
when the low-temperature operation is permanently at a low temperature below the air condensing point of the flue
gas, ie 65 °C
•
Incorrect boiler size due to heat losses of heated space
•
During ingnition when chimney flap is not opened
•
in case of improper handling.
When combustion of wet or damp fuel, nominal power may not be achieved, the boiler becomes excessively clogged.
This results in considerable economic losses, which are reflected in increased fuel consumption and reduced boiler life.
There are several important principles that need to be observed to ensure that the boiler function is safe and economical.
•
customer conscience
•
adequate chimney draft operation
•
clean boiler (drafts and vents)
•
tight boiler - properly installed and sealed cleaning, stoking and ash door
•
Correct boiler output selection for a given heated object
•
Properly dried fuel
