An automatic air-fuel ratio control apparatus for use in a combustion system of a type in which combustion air is preheated, which is so arranged that a push rod depresses one end portion of a rocking lever in accordance with temperature of preheated combustion air and consequently the other end portion of the rocking lever depresses a valve member to correct pressure of working fluid for controlling a flow of fuel so as to obtain best air-fuel ratio, and further that a bearing member for pivotally supporting the rocking lever can be diagonally shifted to change the air-fuel ratio.

Automatic air-fuel ratio control apparatus

A proportional regulation oil burner of low-pressure air type, wherein a second separate air nozzle is disposed between the oil nozzle and the first air nozzle, and a small amount of low-temperature air is fed into the second air nozzle to prevent the oil nozzle from becoming higher in temperature, whereby heavy oil can be used even when the preheating air of high temperature is used.
