Abstract

PURPOSE:To improve safety by making a burner-motor stop immediately when the burner-motor and its detecting line for a rotating speed are abnormal by installing a malfunction detecting means for the rotating speed of a motor for a burner and a malfunction detecting means for the signal of the rotating speed of the motor for the burner sending a stop command to the drive circuit of the motor for the burner. CONSTITUTION:A rotating speed detected by a rotating speed detector 2 discovering the rotating speed of a motor 1 for a burner in which rotating speed is controlled, with two or more pieces of rotation detecting elements 5A, 5B is compared with the rotating speed in a specified range and when the detected one does not exist in the range and continues for a fixed time or more, a malfunction detecting means 3 for a rotating speed sends a stop command to the drive circuit of the motor 1. When the transmitting signal of the detector 2 is judged to be abnormal based on the fact that one of the elements 5A, 5B at least does not send a detecting signal and the abnormal condition continues for a set time or more, a malfunction detecting means 4 for the signal of the rotating speed sends a stop command to the drive circuit of the motor 1. In any case, combustion operation can be therefore stopped immediately.
