ABSTRACT:
Combustion equipment designed to reduce smoke levels and the production of nitrogen oxides has a fuel burner mounted in the upstream wall of a combustion chamber, the fuel burner comprising a central duct partially surrounded by an annular duct, each of the ducts having an array of swirl vanes at their upstream ends and fuel inlet apertures downstream of the respective arrays of swirl vanes. The fuel supply to each of the ducts can be controlled to apportion the fuel flow between the two ducts in dependence of an engine parameter, such as speed, so that at low speeds a majority of the fuel is injected into the annular duct while at higher engine speeds, a majority of the fuel is injected into the central duct.
