Eclipse AirHeat Burner, V2, Design Guide 135, 6/16/2010
System Design
Design
When selecting an AirHeat burner, choices are available
to define a burner that will be safe and reliable for the
system in which it will be installed. The design process is
divided into the following steps:
1.
Burner Option Selection:
• Burner Model / Size Selection
• Burner Style
• Air Supply
• Fuel Type
• Manifold Type
• Mounting Flange
• Burner Configuration
• Gas Pipe Connection
• Control Valve
• Ignition Type
• Flame Supervision
• Control Motor
• Air Flow Switch
2.
Blower Option Selection:
• Power Supply Frequency
• Blower Motor Type
• Blower Inlet
• Motor Orientation
• Remote Blower Sizing
3.
Control Methodology:
• Burner Control
4.
Ignition System:
• Ignition Transformer
• Trial for Ignition
• Ignition Gas Piping
5.
Flame Monitoring System:
• Flame Sensor
• Flame Monitoring Control
6.
Main Gas Shut-Off Valve Train Selection:
• Component Selection
• Valve Train Size
Step 1: Burner Option Selection
This section describes how to select burner options to suit
an application. Use the AirHeat Price List 135 and
Datasheet, 135 when following this selection process.

if you have special conditions or questions.
Burner Model / Size Selection
Consider the following when selecting the burner size:
•
Heat Input -
Calculate the required heat input to
achieve the required heat balance.
•
Process Air Temperature -
Upstream process air
temperature will determine the housing material
required.
•
Combustion Chamber Pressure -
Consider the
effects that large or varying chamber pressures
have on burner performance.
•
Altitude -
Data supplied is based on burner
operation at sea level.
•
Combustion Air Supply -
Combustion air should
be fresh (20.9% O
2
) and clean (without corrosives).
•
Combustion Air Temperature -
Changes in air
supply temperature can affect the burner
performance. The combustion air supply
temperature should not exceed 250° F.
•
Fuel Type -
Variation in calorific value and density
will affect burner performance.
Burner Style
AirHeat burners are available in straight sections only.
The standard housing material is steel, but for upstream
process temperature above 500°F (260°C), the stainless
steel housing option should be chosen.
Air Supply
AirHeat burners can be ordered with or without a
combustion air blower directly mounted to the burner. For
remote blower applications, see "Remote Blower Sizing".
