Abstract

PURPOSE:To maintain a liquid fuel burner by eliminating anxiety and discontent for operators in the preheating time by a method in which output values are judged and processed in a controller and then preheating conditions are displayed in order in plural display sections. CONSTITUTION:In the signal discriminater of a controller 1, drive signals A-D for the values of preheating signals 5a are sent out. When the temperatures at which a liquid fuel is sufficiently vaporized are considered to be 100%, only the display section 61 is driven by drive signal A when 25% temperature is reached, display sections 61-63 are driven by drive signals A-C when 75% temperature is reached, and display sections 61-64 are driven by drive signals A-D when 100% given temperature is reached, showing the completion of preheating. Since the process of temperature rise in the preheating mechanism 4 is displayed in real time in this way, the preheating condition of a burner can be soon notified to operators, thereby eliminating anxiety and discontent for operators during preheating. Disorder in the preheating mechanism can also be notified to make maintenance of the burner easier.
