Firing rate

The burner delivery must be selected within area of the diagrams
(Fig. 2). This area is called firing rates and provides the maximum
delivery of the burner in relation to the pressure in the combustion
chamber.
The work point may be found by plotting a vertical line from the
desired delivery and a horizontal line from the pressure in the
combustion chamber. The intersection of these two lines is the
work point which must lie within the firing rates.
