System Design
Design
When selecting an AH-MA DualBlock 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
• Air Filter
3. Control Methodology:
• Burner Control
4. Ignition System:
• Ignition Transformer
• Trial for Ignition
• Ignition Gas Piping
6
5. Flame Monitoring System:
• Flame Sensor
• Flame Monitoring Control
6. Main Gas Shut-Off Valve Train Selection.
• Component Selection
• Valve Train Size
7. Process temperature control system.
NOTE: Information in Datasheet 163 is necessary to
complete some of the procedures.
Step 1: Burner Option Selection
This section describes how to select burner options to suit
an application. Use List 163 and Datasheet 163 when
following this selection process.
■ Consult
EFE-825,
Engineering Guide, or contact Eclipse Combustion
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
• 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.
