Burner model identification
Burners are identified by burner type and model. Burner model identification is described as follows.
Technical Specifications
Heavy oil net calorific value (Hi): 40.4 MJ/kg (average value).
z
Burners provided with Siemens LMO44 control box: the control box automatically stops after 24h of continuous working. The con-
trol box immediately starts up, automatically.
z
Burners provided with Siemens LAL25 control box: for safety reasons, one controlled shutdown must take place every 24 hours of
continuous working
