    The document provides instructions for heating up a kiln line. It describes adjusting the pressure at the kiln hood and firing the flame with a device or fuse cord. It recommends adjusting the flame to be short and compact, burning in the first part of the sintering zone. The amount of fuel needed for heating depends on the kiln size, starting at 500-1000 liters per hour. It provides a schedule for rotating the kiln as it heats up over 36-48 hours. Proper lubrication of supporting roller bearings is also important during heating.

    1 HEATING UP THE KILN LINE

    Before firing the flame the pressure at kiln hood has to be adjusted to 0 mbar, in case of
    heavy oil combustion pay attention to an oil temperature of at least 120C (spray viscosity2E).

    The firing of the flame takes place with a firing device or with the traditional fuse cord.

    With the primary air (axial and radial air) the flame is to adjust in a short and compact way,
    burning out in the first part of the sintering zone. The amount of fuel for heating up the plant
    depends on the plant size and should be 500 to 1000 l/h at the beginning of heating up.

    Rotation of the kiln during heating up with auxiliary drive, beginning with the cold
    condition:

    Time Rotation
    After ca. 3 hours 180
    4th to 12th hour Every 2 hours 120
    13th to 26th hour Every hour 120
    27th to 34th hour Every 40 min 120
    35th to 40th hour Every 20 min 120
    41th to 46th hour Every 10 min 120
    47th to 48th hour Continuous with auxiliary drive

    While rotating the kiln, the supporting roller bearings have to get enough oil at any time. If
    necessary, the bearings have to be extra lubricated.

    NOTE: If there is no Lagerumlaufschmierung (bearing circulation lubrication?)


    installed, oil must be pumped onto the Lagerzapfen , especially after a longer
    period of stoppage.

    In the first 2 to 3 hours the initial amount of fuel is not being modified.
    When reached a constant kiln inlet temperature, the amount of fuel is increased step by step.
    The whole heating up process should last 36 to 48 hours. (See Heating up-
    Diagram rotary kiln).

    NOTE: During heating up the instructions of the refractory (brick) supplier


    are to be followed!

    Until the first feed of material, the pressure conditions in the kiln have to be adjusted in a way,
    that the fuel burns without formation of CO at the lowest amount of combustion air, and the heat
    is kept in the sintering zone
