Abstract
A liquid or gaseous (fluid) combustible is mixed with a combustion-sustaining gas and fed under pressure into a chamber where the mixture is burned. The mass flow of the combustible (fuel) is normally maintained constant for a combustion chamber of given thermal power output. The pressure in the chamber is continuously detected and the ratio of the mass flow of recirculated exhaust gas to the mass flow of the oxygen-containing gas (air or oxygen), which together constitute the combustion-sustaining gas, is increased when this pressure increases above a predetermined limit and the ratio is decreased when the pressure decreases below a predetermined limit. The ratio is varied by increasing or decreasing the proportion of exhaust gases and thereby decreasing or increasing, respectively, the partial pressure of oxygen in this combustion-sustaining gas.
