Defective flame with sparks

Flame badly shaped with smoke and
soot

Defective pulsating escaping flame
or receding from the combustion ori-
fice

Corrosion inside the boiler

Soot at the chimney exit

1) Atomizing pressure too low
2) Too much combustion air
3) Inefficient nozzle, either fouled up

or worn out

4) Water in the fuel

1) Insufficient combustion air flow
2) Inefficient nozzle, either fouled up

or worn out

3) Combustion chamber unsuitably

designed or too small

4) Delivery nozzle inadequate in re-

spect to the combustion chamber
size

5) Refractory lining unsuitable or ex-

cessive

6) Boiler or chimney ducts clogged
7) Low atomizing pressure

1) Excessive draught (only when there

is a suction fan in the chimney)

2) Inefficient nozzle, either fouled up or

worn out

3) Water in the fuel

4) Dirty disk
5) Excessive combustion air flow
6) Air passage between disk and blast

tube

1) Boiler operating temperature too

low (below the dew point)

2) High sulphur content in the fuel
3) Smoke temperature too low (below

180  °C)

1) Excessive cooling (below 180°C) of

smoke before exit outflow, for an out-
side chimney not adequately heat in-

1) Re-set it at the required rating
2) Reduce combustion air flow
3) Clean it or replace it

4) Remove it from the tank using a

suitable pump (never use the
burner pump for this job)

1) Increase combustion air flow
2) Clean or replace it

3) Reduce the nozzle delivery rate to

suit the combustion chamber ca-
pacity or replace the boiler

4) Increase nozzle delivery rate by re-

placing it

5) Modify it or make it lighter accord-

ing to boiler manufacturer’s in-
structions

6) Clean them
7) Rectify and re-set at the required

value

1) Adjust the suction fan speed by

changing the pulley diameter

2) Clean or replace it

3) Remove it from the tank with a suit-

able pump (never use the burner
pump for this job)

4) Clean it
5) Reduce combustion air flow
6) Rectify the position of the blast tube

1) Increase the operating temperature

2) Change grade of fuel
3) Increase the nozzle delivery rate by

replacing it

1) Improve insulation and close any

gap letting cold air in
