emission data is given for:
– Ambient combustion air (~70°F, 21°C)
– Less than 1000°F (540°C) firing chamber
– Minimal process air velocity
– Low fire input adjusted to minimum input On-Ratio, see page
– Neutral chamber pressure
emissions from the burner are influenced by:
– Chamber conditions
– Fuel type
– Firing rate
– Ratio regulator adjustments
– Combustion air temperature
CO emission is largely influenced by chamber conditions.
Contact your Honeywell representative for an estimate of CO emission
on your application.
