Abstract: An appliance is provided with a cavity wrapper defining a cooking chamber therein. An embossment is formed in a wall of the cavity wrapper and protrudes within the cooking chamber. The embossment has a leading sloped portion. A shroud is located adjacent the wall and includes an outer perimeter edge that is spaced from the embossment thereby defining an exhaust port therebetween. A bracket is disposed outside the cavity wrapper and includes a pair of mounting tabs affixed to an external surface of the wall of the cavity wrapper. The pair of mounting tabs straddling the embossment in a staggered formation.

Abstract: Gasification cooling systems provided herein may include a housing having a fluid passage extending in a flow direction lengthwise along the housing and an annular wall disposed about the fluid passage and having one or more annular steps. Such systems may also include a plurality of heat exchanger tubes downstream of the one or more annular steps and adapted to cool a syngas in the gas passage as the syngas flows in the flow direction.

Abstract: Embodiments of gasification cooling systems provided herein may include a housing, an annular wall, and one or more tangential fluid jets circumferentially disposed about the annular wall. The housing includes an inlet, an outlet, and a fluid passage disposed between the inlet and the outlet. The annular wall is disposed about the fluid passage, and a fluid stream is configured to flow in a flow direction from the inlet toward the outlet. The one or more tangential fluid jets are adapted to inject fluid into the fluid passage to annularly circulate the fluid stream throughout the fluid passage as the fluid stream flows in the flow direction.
