Title: Control device of burner
Inventor: KASADA TOSHIO
IPC: F23N5/26
Filed: 1989-04-17
Abstract: PURPOSE:To obtain a control device of a safe burner which is not operated for a long time under an abnormal combustion state by counting and storing the number of emergency fire extinguishing operation conducted when the output of a flame detector drops below a specified value during combustion, and turning combustion based on normal operation unable to be conducted. CONSTITUTION:When the ion current If of flames is virtually stabilized in the lapse of time from the start of combustion, a microcomputer 15 compares the ion current value If of that time with a threshold of ion current value Io by emergency combustion preset in memory, and sets an emergency fire extinguishing flag stored in memory if If < Io, and judges as emergency combustion and increments an emergency extinguishing counter. When the emergency fire extinguishing counter indicates a value, say, less than 3, the value of the emergency fire extinguishing counter is displayed on an indicator 25, thereby conducting fire extinguishing activities. When the emergency fire extinguishing counter indicates 3, the operation of the microcomputer 15 will be brought to a halt after fire extinguishing operation is conducted. Therefore, combustion will be impossible to carry out.
