During the experimental measurements the same combustion conditions were secured, that is, uniform supply of primary, secondary and tertiary air, the same pressure in chimney (12 Pa), and a maximum dose of 1.5 kg of fuel.
These temperature variations were caused by the location and configuration of the tertiary air system and by the operation of the six-on-six interlaced secondary air system.
The tertiary air ports were moved to a higher elevation.
The main combustion air side of the dual air zone burner is divided into secondary and tertiary air passages.
