Eclipse AH-MA DualBlock Burner, V2, Design Guide 163, 6/19/2012

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

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, 

Eclipse 

Combustion

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

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.
