Arrangement for preparation of a fuel for combustion

摘要

An arrangement for preparation of a fuel for combustion including a burner is provided. The arrangement includes a combustion chamber associated with the burner and in which combustion of a fuel is to take place, as well as means for supplying liquid fuel to the arrangement through an internal passage in the burner for the combustion, solid portions of the burner body being heated by the combustion, wherein the internal passage is located inside the solid portions of the burner body for receiving heat energy evaporating the fuel from these body portions, and that it includes means for conveying vaporized fuel to the combustion chamber to take part in the combustion.

主权项

1. A premix burner arrangement for a gas turbine engine, comprising:
a liquid fuel supply device that supplies a liquid fuel to the arrangement; a combustion chamber; a burner associated with the combustion chamber that combusts a fuel wherein the burner has:
a solid burner body member including an end face that receives heat from the burner operation,an internal passage arranged within the solid burner body member that connects to the liquid fuel supply device to convey the liquid fuel within the burner where the received heat of the solid burner body member is conveyed to the liquid fuel to create a vaporized fuel, wherein the internal passage has a portion that follows a path that spirals inwardly with respect to a longitudinal axis of the burner and that swirl is provided to the evaporated fuel and air by a swirler arranged upstream the combustion chamber, anda vaporized fuel conveying device that conveys the vaporized fuel for combustion within the chamber,wherein the end face of the solid burner body member forms a base of a burner space of the combustion chamber, where the flame of the burner is operatively located and which extends from the base of the burner space towards the combustion chamber.
