PUTTING BOILER IN OPERATION
•
Before the liquid/gas fuel heater boiler is operated, the existence of
the following conditions should be controlled:
•
The liquid fuel in main fuel tank or the daily fuel tank should be heated
to the required temperature turning on the heater circuit.
•
The valves on the liquid fuel circuit should not be opened fully.
•
Burner nozzle should be selected to suit burner and boiler capacity.
•
The pre-heater on the burner should be filled with liquid fuel and any
air in it should be discharged.
•
The boiler thermostats should be adjusted to the suitable value.
•
It should be made sure that the heating system is filled with water.
•
The system should be filled with water and all the valves should be
checked to be open. Air should be discharged from the air valves and
purgers in the system. Circulation pump should not be operated during
air discharge.
•
Circulation pump should be started.
•
The burner should be started from the switch on burner power panel.
•
After the burner is running, nozzle pressure should be adjusted to
burner and boiler power.
•
When the boiler is in steady state (1-1.5 hours after the burner has
started), burner air adjustment should be made using the chimney gas
analysis device.
•
In the case of gas fuel burner, fuel cut-off valves are opened and the
burner is started. In fuel-oil usage, the burner is started after the fuel
is heated in the pre-heater tank.
•
Hourly fuel consumption is calculated with the formula of
B=Qk/(Hu*v).
B : Fuel quantity per hour [kg/h],[Nm

/h]
Q
k:
Boiler output [kcal/h]
H
u:
Fuel lower heating value [kcal/kg],[kcal/Nm

v : Boiler efficiency must be obtained from table on page 9.
•
In liquid fuel applications, appropriate nozzle (45°), pump pressure
(see burner catalog) should be selected.
•
In gas fuel applications, the type of fuel (Natural gas, LPG) and gas
consumption according to line pressure must be checked from the
relevant gauge.
•
If the boiler water is overheated, the circulation pump should be
checked. (It may be turning in reverse due to misplaced connectors.)
If that does not bring a solution, the burner should be stopped and the
installation should be checked.
•
Open the boiler door carefully.
•
Protect the front door and the front smoke chest fire cement surface
from collusion with hard objects (skewer, brush arm, turbulence
makers, etc.).
•
During the initial firing of the boiler after manufacturing, run it at a 25-
30% capacity setting for about 2 hours to let the moisture in the cover
fire cement be disposed.
