QUESTIONS WITH CORRECT ANSWERS
A pulsating effect in the furnace of an oil fired boiler could be caused
by? -correct answer-Insufficient combustion air supply
The burner assembly sprayer plate controls the
. - correct
answer-Flow of the fuel in the whirling chamber
The primary air flow through the burner register provides air necessary for
. -correct answer-Sustained combustion in the
furnace
The boiler superheater raises the temperature of the .-
correct
answer-Steam leaving the boiler
When the boiler firing rate increases, combustion control does what? -
