Title:
CONTROL SYSTEM FOR COMBUSTION DEVICE
Document Type and Number:
Japanese Patent JP3655206
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide a system for controlling a combustion device to eliminate variance in the number of revolution, which is caused by the variation of temperature around a fan in a combustion device.
SOLUTION: In a hot air heater x employing the control system, the fan 22 is controlled so as to have 'the reference number of revolution' according to the burning rate of a burner 21 with the application of a 'reference current' in terms of data in an EEPROM 24. A correction data preparing means 6 in the system prepares correction data to eliminate the difference of the number of the revolution corresponding to temperature difference from the reference temperature by using the number of revolution of the fan 22 measured by a Hall IC 22c and the reference number of revolution based on the ambient temperature measured by a thermister 29. A data correction means 27 corrects the data concerning the reference current in the EEPROM 24 on the basis of the correction data.
