摘要： The present invention relates to an apparatus and method for the generation of directed vapor from a liquid source. Vaporization takes place within a device capable of confining boiling to a geometrically small volume, and expelling it as heated vapor via capillary vaporization. The foregoing is accomplished through the use of a lightweight compact and portable personal vaporization device that generates heated vapor by the flash boiling of small volumes of aqueous liquid in a safe and energy-efficient manner. The flash boiling takes place at the interface between a disk heater and a non-fibrous wick that receives liquid at one surface and generates vapor that is collected and pressurized in grooves at an opposing surface. In an alternate configuration, a heat distributor may be used between the heater and wick. The apparatus and methods are directed toward personal humidification for comfort and therapeutic purposes in the case of aqueous liquids, but may also be used with other, non-aqueous liquids.

摘要： A process for in situ thermal recovery of hydrocarbons from a reservoir is provided. The process includes: providing an oxygen-enriched mixture, fuel, feedwater and an additive including at least one of ammonia, urea and a volatile amine to a Direct-Contact Steam Generator (DCSG); operating the DCSG, including contacting the feedwater and the additive with hot combustion gas to obtain a steam-based mixture including steam, CO2 and the additive; injecting the steam-based mixture or a stream derived from the steam-based mixture into the reservoir to mobilize the hydrocarbons therein; and producing a produced fluid including the hydrocarbons.

摘要： A combustion system and process of operating the combustion system incorporating an electrostatic precipitator, an optional flue gas desulfurizer, and a temperature swing adsorptive gas separator, for post-combustion emission abatement is provided. A very low pressure steam stream may be employed as a first regeneration stream for the temperature swing adsorptive gas separator where the very low pressure steam stream may optionally be recovered from, a very low pressure steam turbine or an auxiliary boiler. A fluid stream at a suitable temperature for regeneration of at least one adsorbent material in the temperature swing adsorptive gas separator may be employed as a second regeneration stream where the fluid stream may optionally be recovered from an electrostatic precipitator, an oxidant preheater, or an auxiliary heater.

摘要： The invention relates to a system and process for hydrogen combustion for industrial or steam generation applications, and more particularly to a hydrogen combustion burner or retrofit kit combustion system and process using a primary pure hydrogen fuel source. The burner or retrofit kit combustion system and process may also use one or more secondary fuels, such as natural gas, methane, propane, or the like, to reduce emissions of CO2. Additionally, the inventive burner, system and process can use a flame temperature reducing fluid for lowering the bulk flame temperature of the burner to increase equipment life and decrease equipment failure. The flame temperature reducing fluid can include flue gas recirculation (FGR), water injection, steam injection, and a combination thereof.

摘要： The present disclosure relates to an L-shaped header of a steam generator including a spiral heat transfer tube, and a coupling structure between the L-shaped header and the heat transfer tube, wherein an upper end and a lower end of a heat transfer tube assembly configured with a plurality of heat transfer tubes are vertically formed, and the upper and lower ends of the heat transfer tube assembly are vertically coupled to a bottom side or a top side of the header. Therefore, the heat transfer tubes constituting the same concentric circle may use the heat transfer tubes formed with the same shape, thereby improving the manufacturability of parts and reducing the manufacturing cost.

摘要： On-demand, hand-held vaporizer that operates primarily by convection. The vaporizer is configured to permit very rapid (e.g., within a few seconds) heating of air drawn through an oven chamber to a predetermined or selectable vaporizing temperature to vaporize a material (e.g., loose leaf plant material, etc.) that is held in the oven chamber. The vaporizer provides efficient transfer of air being heated as well as rapid delivery of vaporizable material to a user.
