Abstract
The 'fuel-air pressure ratio' combustion control system for maintaining a selected fuel-air ratio for a combustion apparatus supplied with air at a substantially constant volumetric rate is improved by means for adjusting the flow rate of fuel in relation to temperature fluctuations of the air. A temperature sensor positioned in the air stream before it mixes with the fuel is connected to a converter which transmits converted temperature signals from the sensor as adjustments of a remote control, secondary valve in the fuel line downstream of a primary valve regulating the flow of fuel. Fuel temperature fluctuations can also be converted into adjustments of the remote control, secondary valve.
