Burner with automatic fuel and air adjuster - has oxygen sensor in flue actuating servomotors of fuel mixt. regulator

摘要

The burner system is regulated by automatic regulators fitted into fluid fuel channels. Fuel is saved by automatic system which responds rapidly to changing operating conditions. The flue channel (3) of heat generator (2) has oxygen sensor (12) for producing actual value signal. Each regulator (14, 17, 20) has servomotor (15, 18, 21). These motors are connected by signal generated on comparison of an actual oxygen content signal with a reference oxygen content signal.
