1.4. Operation Concept and Configuration
1.4.1. Burner Components
The burner includes the following components
:
– burner housing;
– trailing furnace grates;
– fuel firing system;
– burner with ceramic ejector nozzle;
– pellet supply system with driving gear;
– driving gear for furnace grates;
– pressurized air fan;
– electric system
.
The burner housing is the basic unit, also serving as the base for the equipment
installed inside, including the trailing furnace grates and the ignition system
.
The combustion chamber has the air injection holes inside
.
Their diameter is selected
in such a way to ensure the open air flow makes possible the optimal air dosing in the volume
required for the optimal burning of pellets
.
Primary air enters through the pumping holes
located in the trailing elements of the grate
.
The design of the burner and its basic elements are shown on Pic.
