Combustion Chambers with Microdiffusion Combustion of Gas

Problems connected with a quality of combustion process take place in several industries where hydrocarbon fuel is used as a source of heat. Among these problems, the most important are relatively high concentration of NOx, CO, CnHm in combustion products, low thermal-power density of combustion chamber, hardly controllable distribution of the temperature of combustion products at chamber outlet, and complexity of safe cooling of combustion chamber walls. In this paper a novel chamber with single-stage gaseous fuel combustion is proposed [1, 2]. The chamber is of straight-flow type. Distributed fuel feeding over entire cross-section of the chamber is used. Gas combustion is established in short diffusion flames stabilized on fuel manifolds. All the above-listed problems have been solved by ideas used in the combustion chamber design.
