PRECHAMBER OF COMBUSTION CHAMBER Russian patent published in 1997 - IPC

FIELD: power, transport and chemical engineering; combustion chambers of gas turbines and other fuel-burning devices. SUBSTANCE: prechamber contains two circular coaxial bladed air swirlers 1 with opposite twisting of flow and circular fuel manifold 2 arranged between them; fuel distributing devices 3 are mounted on end of fuel manifold. Circular deflectors 4 fitted with baffle plates 5 axially and radially inclined towards manifold are mounted at outlet of swirlers 1. High efficiency of mixing the fuel with air is achieved due to optimal relationship of radial distance between deflectors at swirler outlet, relative height of fuel manifold and angle of twist of flow at minimum length of combustion chamber. EFFECT: enhanced efficiency of mixing fuel. 2 dwg
