SINOPSIS

Investigations were carried out of combustion of premixed air–fuel mixtures and of diffusion fuel jets. Dependences of combustion process parameters on Reynolds number, air–fuel ratio, and the length of combustion zone have been obtained. Investigations were carried out for swirling and nonswirling flows, with cocurrent and countercurrent flows of fuel and oxidizer. Combustion parameters were investigated on fuel ejection into the mixing area with swirling flow of the main air supply. The method of "lean" mixture (1.8 ≤ α ≤ 2.3) combustion at low pressure gradient countercurrent flow is described. The method provides combustion of fuel with high efficiency and low emissions of NOx and CO.
