A bottom assembly unit for a vaporizing burner combustion chamber assembly unit, especially for a vehicle heater, includes a bottom part (24) with a bottom wall. A porous evaporator medium (44) at least partially covers the bottom wall on a front side (42) positioned such that it faces a combustion chamber (20). A ring-shaped holding part (34) has a contact area (40) touching the porous evaporator medium (44). The contact area has a holding section (62) extending radially inwardly from a holding part circumferential wall (36) and extends over the porous evaporator medium (44) in a radially outer area (66). A plurality of contact projections (68) are arranged at spaced locations from one another about the longitudinal axis and extend in the direction of the porous evaporator medium. The porous evaporator medium (44) is pressed by the contact projections (68) in a radially outer area (66) against the bottom wall.

A portable fireplace is disclosed. The portable fireplace may include a receptacle and a refractory liner. The receptacle may have a base and a wall, and the wall may extend upward from the base. An interior side of the wall and an interior side of the base may define a burn chamber that is open to an environment external to the receptacle. The refractory liner may be positioned within the burn chamber, and the refractory liner may engage the interior side of the base and the interior side of the wall. The refractory liner may be configured to receive and absorb at least a portion of a flammable substance.

Dishwasher appliances and vents for dishwasher appliances are provided. The dishwasher appliance includes a chamber for the receipt of articles for cleaning, and a door for selectively opening and closing the dishwasher appliance, the door having an interior wall and a bottom. The dishwasher appliance further includes a conduit disposed within the door. The dishwasher appliance further includes a vent for controlling the egress of fluid from the chamber through the first end, the vent received into the door. The vent includes a generally planer body, and a plurality of aperture assemblies defined in the body. Each of the plurality of aperture assemblies extends generally radially within the plane. The vent further includes a plurality of ribs extending from the body.

A combustion apparatus is provided. The combustion apparatus includes a fuel reservoir storing fuel therein, and a main body connected to the fuel reservoir by a flexible tube. The main body receives fuel from the fuel reservoir and combusts the fuel therein. The main body is partitioned into an upper space and a lower space by a partition plate. The main body includes a combustor that is provided in the upper space and combusts fuel supplied from the fuel reservoir, a blower that is provided in the lower space to supply air to the combustor, and a heating unit that is removably coupled to the combustor and completely combusts air incompletely combusted in the combustor. The combustion apparatus completely combusts liquefied animal and vegetable oil, thus reducing a tar generation rate.
