Based on the analysis of the varnish materials and measurements performed over extended
period of time, it is certain that the materials and concentrations processed during the
measuring gave a representative cross-section of the production activity. Table 18.1.4
shows a summary of the varnish and solvent amounts processed per day, which were emitted
from chimneys 1 to 4.

At the chimneys, the following exhaust air parameters were established:
Chimney diameter mm
Exhaust air flow rate m/s
Exhaust air temperature °C
Humidity %
Volume flow (operation) m³/h
Volume flow Nm³/h
Heat flow MW
Table 18.1.5 contains a summary of the established emission values expressed in mg C
total/Nm³ as well as the mass flow g C/h.
