Description
The RAGH type regulator has been designed for burner with preheated air. It is able to maintain
a constant ratio between air and gas flow during the different phases of burner working. In a
regenerative or recuperative burner with the same air inlet pressure, the air flow changes during
burner working and aging. Air flow depends on air preheating grade and the presence of dirty
on recuperator or regenerator. RAGH is able to supply a gas pressure proportional to Air
differential pressure, which is directly linked with air flow.
