  • Page 5: General Features

    PART I: SPECIFICATIONS PART I: INSTALLATION GENERAL FEATURES This particular burner series has been studied to use compressed air or alternatively steam, to atomize heavy oil. In this way we have achieved higher efficiency compared to mechanical atomization. These burners are equipped with a low pressure nozzle which permits to save fuel and, above all, to preserve the whole system.

  • Page 18: Connecting The Pump

    OIL TRAIN CONNECTIONS About the use of fuel pumps Do not use fuel with additives to avoid the possible formation over time of compounds which may deposit between the gear teeth, thus obstructing them. After filling the tank, wait before starting the burner. This will give any suspended impurities time to deposit on the bottom of the tank, thus avoiding the possibility that they might be sucked into the pump.

  • Page 22: Electrical Connections

    ELECTRICAL CONNECTIONS Respect the basic safety rules. make sure of the connection to the earthing system. do not reverse the phase and neutral connections. fit a differential thermal magnet switch adequate for connection to the mains. ATTENTION: before executing the electrical connections, pay attention to turn the plant’s switch to OFF and be sure that the burner’s main switch is in 0 position (OFF) too.
  • Page 23 Rotation of electric motor Once the electrical connection of the burner is executed, remember to check the rotation of the electric motor. The motor should rotate according to the “arrow” symbol on the body. In the event of wrong rotation, reverse the three-phase supply and check again the rota- tion of the motor.

    ADJUSTMENT FOR OIL OPERATIONS Before starting up the burner, make sure that the return pipe to the tank is not obstructed. Any obstruction would cause the pump seal to break. ATTENTION: before starting the burner up, be sure that the manual cutoff valves are open. Be sure that the mains switch is closed.
  • Page 32 Compressed air adjustment ATTENTION: set the pressure value about 1 bar, at the pressure gauge 47 (see Fig. 17). check it before open valve 16! To start the burner set the oil and atomisation medium pressure at about 1 bar, as first trial. then, regulate the burner checking the com- bustion values at the chimney, according to the paragraph "operation", and adjust the starting point according to the regulation.

  • Page 85 Actuators references An incremental transducer is used to ensure position feedback. Referencing of the actuators must be performed after power-on. In addition, at the end of each shutdown in phase 10, the actuators are referenced to ensure that individual stepping errors, which could lead to shutdown, do not accumulate.

  • Page 86: Commissioning The Burner

    COMMISSIONING THE BURNER The LMV2x complete programming must be performed on units that has never been set before or reset units (e.g. spare parts). The programming procedure is performed by setting the following main parameters: if LMV.. is a spare part, insert burner ID (parameter 113) at least 4 digit. type of fuel train (parameter “201”) air/fuel ratio curvepoints (Block “400”) maximum load percentage (parameter “546”)

  • Page 88 Lo 3-stage In the example the Gmod gas train has been set (Configuration “1”). Choose the fuel train by pressing ENTER, then press “+” / “-”. Press ENTER to confirm: number “1” will appear on the right side of the display.
  • Page 89 CAUTION: at the first burner adjustment, it is recommended to set the maximum output P9 at the same value (or little higher) of the ignition point, in order to safely reach point P9 next (see next paragraph). By pressing “+” the display will show: The burner is ready to startup.

  • Page 90: Warm Setting

    Warm setting Once pressed button “enter” and the chain thermostats open (X5-03 terminals), the LMV.. show Ph12.Then close the chain termostat and the unit performs the prepurge cycle (see “Phases List”) and stops at the ignition point P0 without ignition anyway. By pressing “+”, the burners lights abd the air/fuel ratio can be properly set in presence of flame.

  • Page 92 BURNER STARTUP WITH LMV2x ALREADY PROGRAMMED Once the LMV turns on, the AZL display will show The burners is basically factory set. The air/fuel ratio curve is set with the maximum output point P9 a little higher or equal to P0. To adjust the burner on the plant site, adjust the maximum output point to the flow rate values really requested.
  • Page 93 Set the air/fuel ratio curvepoints as described on chapter “Programming the LMV2x” Note: the other phases are Ph60 = operation (OP= in modulation) Ph62 = travelling to shutdown Ph70 = off but in prepurge after the burntime Ph72 = travelling to postpurging Ph74 = postpurge (countdown is displayed) Press ESC the parameter “546”...
