How your FBR Burner operates
As soon as burner takes the order from D.B. control
to fire :
· Burner's Gas pressostat : (Gas low pressure pressostat)
checks the gas incoming (supply) pressure to burner to be
higher than the pressostat's regulated value. If pressure
is not sufficient, gas pressostat will "lock out"
the burner or will complete the testing cycle waiting for
the gas pressure to rise over pressostat's regulated value.
- Burner's Fan starts air washing the combustion chamber to
secure absence of concentrated gas
before Ignition.
- Burner's Air pressostat (Air low pressure pressostat) checks
the air pressure to be higher than the
pressostat's regulated value to secure appropriate combustion.
If air pressure is not sufficient, Air pressostat will "lock
out" the burner.
· After ~30 secs, Ignition starts.
· Two seconds later, the 2 Gas valves (Operating and
Safety) are ordered to open (see description how the valves
operate).
· During the next 3 secs, Ionization probe checks for
flame presence. If there is no flame, burner will "lock
out".
Burner's Electronic Control box, controls all above checks.
When testing cycle is completed satisfactory, burner will
keep firing .Otherwise will "lock out" (see trouble
-shoot information).
Adjust your burner's capacity (heating value) according to your
barn size i.e. according to your fan's motor size (i.e. amount
of air circulating in the barn).
Consult your VCU's manual for the recommended capacity (heating
value).
Small variations on supplied Btus (+5 -10 percent) are acceptable.
Small differences in Gas pressure at your pressure regulator
are acceptable.
Serious Gas pressure fluctuations at your pressure regulator
will affect burner's capacity (supplied Btus/hr).
*Note : Gas pressure increase of decrease at your pressure regulator
will accordingly increase or decrease Burner's capacity.
Gas pressure at your pressure regulator 8"-12" is
acceptable as long as burner's Operating Valve, Air damper and
Combustion Head are properly adjusted for the required capacity.
It is not recommended to exceed 12" pressure with the burner
in operation.
