Abstract
A lean-burn combustor for a gas-turbine engine has a radial inflow pre-mixing, pre-swirling burner with a central burner face which forms the upstream wall of a pre-chamber of the combustor. A circular recess is formed in the burner face, the recess having at least one pilot fuel injector for introducing pilot fuel tangentially into the recess, whereby the burner runs cooler and combustion characteristics are improved.
