Positive, this mode of operation is acceptable in an emergency if economizer or boiler tube got leakage.
Following precautions should be followed:

  • The exhaust gas temperature at the outlet of the Main Engine is 400 deg C or less
  • Avoid starting the boiler circulating pump while Main Engine is in operation and no water in economizer. If water will be suddenly supplied by mistake, the thermal shock will damage the economizer.
