Burner Notice when buying

Notice when buying:
The entire diagram was made by the effective standard in the experimental boiler. The real condition may be different because of the
following factors:
a. the pressure of boiler may not be the same. So the capability of which the burner overcomes the boiler pressure is different a ccording
to the different standard working pressure.
b. the motor of the burner may not reach all of the power range when the heating output (the ratio-kcal/m3of the combustion chamber
output power and the relevant Capacity:)of the burner capability reach to a high level.
c. When the real conditions were different with the referring conditions (pressure and temperature). The output of the burner should
be adjusted.
