The vertical arm is substantially vertical in an operative position of the steam generator.

A device for converting a liquid into vapor includes an enclosure, a heating surface with a downward slope arranged in the enclosure, and a liquid inlet port connected to an upper portion of the heating surface so that a liquid introduced from the liquid inlet port flows on the heating surface. The device also includes a vapor outlet port formed through a wall of the enclosure. The heating surface includes a heat transfer pipe configured to allow the flowing of a heat transfer fluid to heat the heating surface, and a corner piece including a U-shaped cross-section with a semi-circular portion arranged around the heat transfer pipe and an upper portion forming an opening on the enclosure.

A boiler has a shell surrounding a vertical centerline. The shell defines an inner surface having an inner diameter and an inner length extending between an upper upstream end and a lower downstream end. The inner surface defines a hollow interior, the boiler having a pre-combustion zone, a combustion zone downstream from the pre-combustion zone, and a post-combustion zone downstream from the combustion zone. The shell is tapered outward along its length in at least a portion of the combustion zone. An oxidizer inlet is in fluid communication with the pre-combustion zone, and a fuel nozzle introduces fuel into the combustion zone. A tube assembly is mounted in the hollow interior of the shell for transferring heat to fluid flowing through the tube assembly. A flue duct is in fluid communication with the post-combustion zone for transporting flue gases from the hollow interior.

An instantaneous heater (51) is mounted in a casing (20) of a smoke machine (10). The instantaneous heater (51) includes a heating rod (52), a flow guiding member (131) mounted around the heating rod (52), and an outer tube (64) mounted around the flow guiding member (131). The flow guiding member (131) includes an inner periphery (137) abutting an outer periphery (58) of the heating rod (52). A shallow, rectilinear heating passage (151) is defined in the inner periphery (137) of the flow guiding member (131) to permit a small amount of oil to pass therethrough. The oil can be directly and completely heated and vaporized by the heating rod (52) into smoke.

An electronic cooking apparatus having a steam supply device for supplying steam to a cooking chamber of an oven is provided. The electronic cooking apparatus may include a steam generating device including a steam supply portion that generates steam and supplies the steam to a cooking chamber, and a water level sensing module that senses a level of water inside of the steam supply portion using a low water level sensor and a high water level sensor. In addition, the electronic cooking apparatus may include a water supply pump that supplies water from a water tank to the steam supply portion; a drain pump that collects condensed water from the steam supply portion to the water tank; and a controller that controls on/off operations of the water supply pump or the drain pump according to a change in the level of water in the steam supply portion sensed by the water level sensing module.

A MEMS vaporizer is described which can be used for electronic cigarettes. The vaporizer mainly composes: a silicon substrate, a micro-channel array, a membrane suspending over the micro-channel array and supported by the silicon substrate, a resistance heater and a resistance temperature sensor are disposed on the membrane. Since the vaporizer is a silicon-based integrated actuator which provides advantages including small size, compact structure, lower power consumption, lower cost, increased reliability, higher precision, and more environmental friendliness.

A steam generator system for a cooking appliance includes an in-line heating element coupled to a heating tube, wherein water from a water reservoir is gravitationally fed into the heating tube for heating by the in-line heating element to produce a hot water and steam mixture. A first supply line is coupled to the heating tube to carry the mixture to a separator without the need for moving or complex pump parts. The separator separates steam and hot water from the mixture of the two. A second supply line is coupled to the separator at a first end and opens into the cooking cavity of the cooking appliance at a second end. The second supply line is configured to supply steam separated at the separator to the cooking cavity via a steam outlet disposed in the cooking cavity.

The present disclosure relates to atomizers for an aerosol delivery device such as a smoking article. The atomizer may include a liquid transport element and a wire extending along at least a portion of a longitudinal length thereof. The wire may define contact portions configured to engage heater terminals and a heating portion configured to produce heat. The heating portion may include a variable coil spacing. In other atomizers, the wire may extend at least partially through the liquid transport element proximate the contact portions. Related inputs, cartridges, aerosol production assemblies, and methods of forming atomizers are also provided.
