Abstract: A cooktop and appliance is provided that may include a first hob zone having a fixed gas receptacle, a first interchangeable burner, a second interchangeable burner, and a first gas flow switch. The first interchangeable burner may be selectively positionable at the first hob zone and define a fuel output area. The second interchangeable burner may also be selectively positionable at the first hob and may define a fuel output area smaller than the fuel output area of the first interchangeable burner. The first gas flow switch may be disposed at the first hob zone to selectively engage one of burners. The first gas flow switch may include a valve upstream of the fixed gas receptacle to selectively restrict gas flow upon engagement of the first gas flow switch with one of the first interchangeable burner or the second interchangeable burner.

Abstract: A combustor assembly including a combustor liner defining therein a combustion chamber for the downstream flow of a main fluid. At least two annular trapped vortex cavities are located on the combustor liner and staged axially spaced apart. A cavity opening is located at a radially inner end of each of the at least two annular trapped vortex cavities spaced apart from a radially outer wall and extending between an aft wall and a forward wall of each cavity. A plurality of injectors are configured tangentially relative to the circular radially outer wall to provide for an injection of air and fuel to form an annular rotating trapped vortex of a fuel and air mixture within a respective annular trapped vortex cavity. The annular rotating trapped vortex of the fuel and air mixture at the cavity openings is substantially perpendicular to the downstream flow of the main fluid. A gas turbine engine including the combustor assembly is disclosed.

Abstract: Apparatus for the combustion of vanadium-containing fuels that makes use of the extremely high reactivity of the vanadium-containing fuels for combustion in a dust furnace. To avoid disadvantageous slag caking in a combustion area and in particular in the vicinity of the feed nozzles, e.g. for the pulverized fuel-air mixture and for combustion air, in a dust furnace, a top burner is placed in a roof of a combustion area and at least one dust nozzle is so positioned for the supply of the pulverized fuel-air mixture that a return flow of liquid slag particles to the top burner is prevented.
