<P>PROBLEM TO BE SOLVED: To provide a combustion equipment capable of appropriately conducting a block detection operation even in the case that action/stop is repeatedly used at relatively short time intervals, in the combustion equipment with a block detection means 18 for conducting the block detection operation for detecting a degree of blocking of an air supply passage and an air exhaust passage based on an electric current value detected by a current detection means when a target rotation number is set to be a predetermined block detection rotation number, a fan is operated by a fan controlling means 173 and a rotation number detection means detects a rotation number of block detection. <P>SOLUTION: The block detection means 18 has a timer memory means 184 for integrating and storing measurement time of an operation timer 181 for measuring time when a burner is burning and the fan is operating every time the fan is operated and an integration time determination means 186 for conducting the block detection operation for detecting the degree of blocking of the air supply passage and the air exhaust passage of the burner which burned immediately before in the case that the integrated time stored in the timer memory means 184 reaches predetermined time. <P>COPYRIGHT: (C)2006,JPO&NCIPI |
