摘要：
A premixing device is provided. The premixing device includes a fuel inlet configured to introduce a fuel within the premixing device and an air inlet configured to introduce air within the premixing device. The premixing device also includes a plurality of swirler vanes configured to provide a swirl movement to the fuel and/or air to facilitate mixing of the fuel and air to form a gaseous pre-mix, wherein a shape of each of the plurality of swirler vanes is selected to control an axial velocity profile of the fuel and/or air within the premixing device.
