Datasheet 110-58/22/2012
Version 5
1 Maximum inputs for packaged blower versions are given for the standard combustion air blower without an inlet airfilter.
2 For proper performance, this pressure must be kept constant across the burner operating range.3 See Design Guide 110 for more information about typical fuel composition and properties.4 All weights are approximate.• All information is based on laboratory testing. Different chamber conditions will affect the data.• All inputs based upon gross calorific values and standard conditions; 1 atmosphere, 70°F (21°C).• Eclipse reserves the right to change the construction and/or configuration of our products at any time without being
obliged to adjust earlier supplies accordingly.

Performance Graphs
NOx Emission data is given for:• Ambient combustion air ~70°F (21°C)• Less than 700°F (370°C) firing chamber• Minimal process air velocity• Low fire input adjusted to 40,000 Btu/h (12 kW)• ppm volume, dry @ 3% O2
• Neutral chamber pressure
Emissions from the burner are influenced by:• Chamber conditions• Fuel type• Firing rate• Ratio regulator adjustment• Combustion air temperature
CO emission is largely influenced by chamber conditions. Contact your local Eclipse representative for an estimateof CO emission on your application
