A fuel swirler has a swirler housing defining an interior chamber having a fuel outlet at a downstream end. A swirler core is mounted inside the interior chamber. The swirler core has a downstream end portion with one or more fuel channels disposed thereon. The one or more fuel channels is in fluid communication with the fuel outlet. An internal bore extends longitudinally through the swirler core. The internal bore has an inlet connectable to a source of fuel. One or more exit holes fluidly connects the internal bore to the one or more fuel channels. An annular air gap is provided radially between the swirler housing and the swirler core for thermally shielding the internal bore.
