Abstract
1528827 Burner controls SONY CORP 18 May 1976 [28 May 1975] 20517/76 Heading F4T A burner control system comprises a flame detector 2, disposed in the flame 1. a transistor Q 1 , D.C. voltage biasing circuits D 1 , C 1 , R 1 , for supplying a control signal to the transistor, which latter is in the “ON” condition when a flame is present, and an A.C. signal is supplied to the transistor via a transformer T 1 through a capacitor C 2 and an amplified A.C. signal EC is derived when Q 1 is “ON”. In operation, when a flame is present and Q 1 is “ON”, pulse-like signal EC is fed to an SCR S 1 , which forms a switching element through a capacitor C 3 . A relay 12 is energized when S 1 is “ON” and this relay opens fuel valve 13 to thus supply burner 3. If the flame goes out, transistor Q 1 is brought to the “OFF” state and signal EC does not appear; relay 12 is de-energized, and valve 13 is closed. An auxiliary electrode 5 may be provided, connected to a negative voltage source, so as to increase the sensitivity of the system. SCR, S 1 may be replaced by a transistor, and an emitterfollower stage may be added to the circuit (Q 4 , SCR S 2 , C 5 , P 9 -R 13 , and C 5 ), Fig. 4 (not shown). A flame indicator I may be provided.
