Abstract
A continuous combustion device of the type having a combustion chamber and an outer casing forming with it an annular air delivery passage for distributing a continuous supply of compressed air into the combustion chamber, and a fuel injector at one end of the combustion chamber. The combustion chamber has a pattern of holes connecting the air passage with primary and secondary combustion zones within it. The invention provides adjustable means for controlling the flow of delivery air in the annular passage to proportion the relative air distribution to the primary and secondary zones so as to reduce polluting emissions under varying load conditions. Preferably, the hole pattern is designed to provide a lean primary zone fuel-air ratio at full power conditions and early quenching of the flame in the primary zone. The regulating device may take the form of adjustable baffle means and for proportioning the distribution of the flow of air in the annular passage.
